When you’re working at your PC it can be a chore to plug it in to transfer photos form it, or to find it and pick it up to read and respond to text messages. Windows now comes with an app called Your Phone which you can search for in the Start Menu that will allow you to drag and drop photos from your phone to your PC and to read, respond to, and send SMS text messages.
It’s helpful if both the phone and the PC are connected to the same Wi-Fi network, though Your Phone can also connect to your phone over its cellular network.. Through the Your Phone app you can perform the following tasks.
Read and Respond to SMS Text Messages – You can type text messages and replies from your PC keyboard. You can even insert emojis, GIFs, photos and more into messages.
Choose which SIM card to use – If your phone supports more than one SIM card, you can choose which to use for call and messages in the Your Phone app.
View and Copy your Photos – Any photos you have taken on your phone will be viewable in the Your Phone app. You can then simply drag and drop them from the app onto your PC, say to File Explorer, to copy them directly.
View and Receive Notifications – With your Phone connected to the Your Phone app, you can choose to receive any notifications on the device, such as calls and received SMS Text Messages, as pop-up notifications on your PC’s desktop. You can also view outstanding notifications on the phone from within the Your Phone app.
Make and Receive Phone Calls – This feature is rolloing out, and not every handset supports it yet. Once complete you will be able to make and receive phone calls directly from your PC, without needing to find and use your phone itself.
The app works with both Android and iOS smartphones and the setup process talks you through how to get started with the app when you first run it. Keep an eye on this app too, as its functionality will be expanded over time to include being able to run apps from your phone in windows on your PC’s desktop.

|Press Release 12-15. April 1999, Turtle Bay Resort, Oahu,
Consortium (TINA-C) of 46 carriers, suppliers and technology companies meets in Hawaii
this month to present the telecom industry with a modern, forward-looking software
architecture to address ever-increasing customer demand for innovative new services.
The TINA Conference '99 will hear feedback from major
carriers such as Sprint Corp., NTT Corp., Deutsche Telekom and France Telecom about real
TINA deployments in their networks. Specialist manufacturers such as Expersoft, Iona, and
Starvision are expected to present their latest TINA-compliant products, and carriers will
present tough new requirements for the real-time control and management that only TINA can
"We believe TINA concepts and principles are
mainstream now. We're beginning to see some real products built to these
specifications," said Deb Guha, Chief Executive Officer, TINA-C.
After an initial day of tutorial and workshop sessions,
TINA '99 kicks off with panel discussions and technical paper presentations from Alcatel,
BT Labs, CSELT, Hewlett-Packard, Korea Telecom, Lucent Technologies and many others.
Subjects explored include the TINA Service Architecture; the integration of TINA with
legacy Intelligent Networks, agents for Advanced Telecom Services, and distributed billing
The conference will hear keynote speeches from Stagg
Newman, chief technologist at the Federal Communications Commission, and Thomas Rowbotham
of BT Labs. The concluding day and a half is set aside for a meeting of TINA-C members who
will hear reports from consortium Working Groups, discuss the latest research and
demonstrate products based on the TINA architecture.
"In the current telecom industry environment of rapid
mergers and equally rapid dissolution of alliances, TINA results are particularly useful
in helping cushion technology differences," said Hendrik Berndt, Chief Technology
"We need to deploy ubiquitous services level
over POTS, mobiles, and multimedia/voice over packet: the best approach is to port
intelligence from legacy networks to new networks through common call servers and common
Intelligent networks. TINA provides tools to make this decoupling of control and transport
", says Martine Lapierre, TINA-C President and Alcatel Switching and Routing Division
Deutsche Telekom and France Telecom will present the
conference with results of their joint project, SATIN (Software Architecture using TINA
for IN). The two carriers recently completed the design and implementation of a service
platform reaching across both their networks, integrating TINA concepts with their
existing Intelligent Network architectures.
NTT will also report on its work over the past three years
on integrating the TINA architecture into its network technologies in Japan.
US operator Sprint recently announced it will reengineer
its combined voice, data and video network, ION (Integrated On-demand Network),
incorporating TINA architecture and specifications. Representatives from Sprint will
describe a TINA-compliant provisioning system based on ATM, and explain how
standardization will help them better manage multivendor relationships.
"The biggest single issue for the TINA Consortium has
been 'when will it be real?' Sprint's ION announcement and projects like SATIN indicate
that the time is now," said Joe Sventek, General Chair of the Conference and
Hewlett-Packard's TINA-C Technical Forum member. "The industry has realized for some
time that more complex services require a more sophisticated control plane than that
provided by the Intelligent Network. TINA provides a conceptually clean platform and
appears to be ready for primetime."
Since its formation in 1993, TINA-C has developed sophisticated software specifications
addressing the urgent need to migrate networks from the 'switch-centric' model to a
Distributed Processing Environment (DPE). In the TINA model, intelligence is sited
increasingly at the edge of the telecom network. The TINA DPE concept builds on the
computer industry's research into distributed processing, applying it to a range of
network devices and user terminals. Ultimately, in the TINA model, even the humble
cellphone becomes an intelligent network device.
Now TINA-C is ready to promote its work aggressively by
bringing TINA products to the attention of the wider industry. By year-end 2000, the
Consortium aims to ensure the availability of large-scale deployments of TINA-compliant
products and TINA-based services.
The need for TINA
In a world already replete with a multitude of services, the addition of even more
sophisticated end products can be a nightmare for those who create, deploy and manage the
service - compounded by a tradition of legacy, multiple-vendor architecture.
In the face of the current rapid changes, there are several
questions to be answered: How can the industry harness the new technical opportunity? How
can it provide versatile multimedia services over the Internet and traditional telecom
networks? How can it keep in check the cost of creating, deploying and managing these
services? And, how can it incorporate flexibility in the service software for current and
future network technologies?
Many believe that a new approach is needed, but one which
can also interwork with existing systems and standards. The answer is to define a new
software architecture that capitalizes on the latest advances in computer and telecom
technologies, to rationalize complex software for services and network management. The
answer is TINA.
TINA is an object-oriented software architecture designed to separate high level
applications from the underlying physical telecom infrastructure.
Control and management functions that are normally sited at the switch are migrated onto
servers, using a unified TINA architecture based on a distributed processing environment
(DPE). This allows control and management features to be deployed flexibly within the
network, instead of being forced to reside on a particular system at particular
geographical locations. The TINA DPE can be based on the Common Object Request Broker
Architecture developed by the Object Management Group (OMG), which is a member of TINA-C,
and also runs over JAVA or DCOM at the terminal side. By migrating intelligence from the
core network to user terminals, TINA combines the distributed character of the Internet
with the inherent reliability, quality of service and security of telecom networks. When
integrated, these two technologies offer an unprecedented opportunity to enable versatile
multimedia and information services and to innovate the way these services are created and
A number of Reference Points are defined within TINA. These
provide for clear separation between the roles of each player in the industry (for
instance between retailer and consumer), enabling new entrants and established companies
to expand their businesses with maximum flexibility.
The TINA Consortium (TINA-C) was formed in 1993 by 40 telecom carriers, suppliers and
computer manufacturers as a co-operative body to define a common software architecture for
telecommunications. Since then, and through interaction with industry bodies such as the
Object Management Group, the ATM Forum, DAVIC, ITU-T and the TeleManagement Forum, TINA-C
has assisted the telecom industry in improving the way services are designed.
At the end of 1997, TINA-C delivered its completed set of
validated architectural specifications. At this point the consortium decided to
restructure to drive forward the adoption of TINA in the marketplace, forming separate
interest groups to address Intelligent Networks, Mobility, Service Management, Service
Access and Provisioning, Electronic Commerce, Security, Application of TINA, the
Distributed Processing Environment (DPE), IP control and Management, and Compliance and
The 46 TINA-C members include: Alcatel, AT&T, BT, Cable
and Wireless, Cegetel, China Ministry of Information Industry, CSELT, Deutsche Telecom,
Eurescom, Expersoft, France Telecom, Fujitsu, Hewlett-Packard, Hitachi, IBM, Iona, Korea
Telecom, KPN, Lucent Technologies, Marconi Communications, MCIWorldcom, NEC, Nortel
Networks, NTT, OKI, OMG, Sharp, Siemens, Sprint, Starvision, Sun Microsystems, Swisscom,
Tadiran, Telcordia (Bellcore), TeleDanmark, Telenor, Telia, Telkom, Telstra, Toshiba.

Expérience ICE – Instrument Champ Electrique
ICE Experiment – Electric Field Instrument
1- Scientific Objectives.
The main objective of the ICE experiment is to detect and characterize the electromagnetic perturbations in the ionosphere that are associated with seismic activity. As a secondary objective, this instrument also aims at characterizing the electromagnetic effects that can be generated by tropospheric storms in the ionosphere. In addition, it will provide real time observations that can be of use for space weather purposes.
In the last twenty years a number of papers have reported the detection of electromagnetic signals related to earth's seismic activity. The corresponding measurements cover a large range of frequencies, from ULF to HF, and were obtained by ground-based instruments as well as from satellite probes. In many cases, not only the understanding of the phenomena but also their proper characterization has proven to be difficult due to the weakness of the signals, the relative paucity of observations and hence their subsequent lack of meaningful statistics and the difficulty of removing other natural signals that can mix with, and indeed sometimes mask, those induced by seismic activity.
The objective of the ICE instrument on DEMETER is thus to perform a continuous survey of the DC and AC electric fields over a wide frequency range and with a high sensitivity in order to search for possible electrostatic and/or electromagnetic waves in the ionosphere that might be induced by seismic activity. The instrument and the onboard data processing have been designed to provide an optimum set of data in the various frequency ranges, emphasizing full characterization of the 3 components of the waves at frequencies below 1 kHz and single axis waveform transmission and spectrum measurements at higher frequencies.
2- Description of the experiment.
The ICE experiment consists of 4 spherical sensors with embedded pre-amplifier electronics mounted on the ends of 4 booms or antenna “arms” and associated electronics, included in the BANT module, to fulfill the onboard signal processing requirements. When measuring the potential difference between two of these sensors, ICE operates as a double probe instrument in which the component of the electric field is determined along the axis defined by the two sensors. Any pair of sensors among the four can be used for this objective which enables the 3 components of the DC and AC vector electric field to be obtained. The electronics encompasses an analog part with a set of filters and amplifiers to process the analog signals from the sensors and a digital part to carry out the waveform digitization, power spectra computation and telemetry interfaces.
Four frequency ranges have been defined, DC / ULF [0-15 Hz], ELF [15 Hz-1 kHz], VLF [15 Hz-17.4 kHz] and HF [10 kHz-3.175 MHz]. Depending on the frequency range and on the spacecraft and ICE modes of operation, the data that are stored in the mass memory can be the waveform of the signal obtained from either the voltage difference between two sensors or that measured by a single sensor and the spacecraft potential, and/or the power spectra of the signal obtained from the voltage difference between two sensors. The data management scheme is described in more details in paragraph 2.2 below.
Figure 1: Position of the ICE sensors on the spacecraft
The 4 sensors, labeled S1, S2, S3 and S4 in Figure 1, are spherical aluminum electrodes 60 mm in diameter each mounted at the end of a 4 meter deployable boom. With such a length and the proper orientation of the booms as shown in Figure 1, the sensors are kept at a sufficiently large distance of the spacecraft and its wake which is induced by the motion of the spacecraft within the ionospheric plasma at meso-thermal orbital velocities. Disturbances in the measurements that can arise from either the extended plasma sheath or the wake of the spacecraft should therefore be negligible under the plasma conditions that are expected along the orbit of DEMETER. Due to the remote position of the sensors with respect to the spacecraft body, electromagnetic interferences generated by the spacecraft subsystems or other payload instruments are significantly reduced. Finally, the orientation of the 4 booms have also been chosen so that the 3 components of the electric fields that can be obtained from the voltage differences between individual sensors, as indicated below, are close to a three axis orthogonal configuration.
The sensors are coated with a thin layer of carbon filled epoxy in order to minimize the variations of the surface potential over the surface and improve the quality of DC electric field measurements. The spherical shell of each sensor includes a small electronics board consisting of a unity gain preamplifier and a polarization current source. The current intensity, which is the same for all 4 sensors, can be adjusted by telecommand in order to keep the sensor sheath impedance to a sufficiently low value irrespective of the varied plasma conditions that are anticipated along the orbit. A low impedance is desirable to maintain negligible phase shifts for the signals in the ELF range where the electric field data are used to determine the wave propagation vector.
2.2- Data management.
Signals from the 4 sensors can be combined to provide 3 components of the electric fields. The nominal configuration of these 3 components is the following:
- E12 (≈ along the Y axis of the spacecraft) = S1-S2
- E34 (≈ along the Z axis of the spacecraft) = S3-S4
- ER = E13 = S1-S3
As seen from above, the S1 and S3 sensors are used to measure 2 components of the electric field vectors. In order to minimize the detrimental effects that might arise should any of them fail, a telecommand order is available to replace them by respectively S2 or S4 in the ER component. Thus E12 and E34 are sent to telemetry irrespective of the sensors status and the third component ER can be changed to E23 (=S2-S3) if S1 fails or E14 (= S1-S4) if S3 fails.
The onboard data processing and data storage in the mass memory depend on frequency range and on the mode of operation of the spacecraft, Burst or Survey, as well as, to a lesser extent, on the sub-mode of operation of the ICE instrument.
2.2.1- DC and ULF measurements.
In both the Burst and Survey modes, signals from each of the 4 sensors, filtered and amplified in a 0-15 Hz bandwidth, are digitized with 16 bits and stored in the mass memory.
2.2.2- ELF measurements.
The 3 ELF electric field components that will be used to derive the detailed propagation characteristics of the electromagnetic waves are only available in the Burst modes. They are filtered and amplified in a 15Hz-1kHz bandwidth, digitized with 16 bits and stored in the mass memory.
2.2.3- VLF measurements.
Only one of the electric field components is processed. In the nominal configuration this is the E12 component, but a telecommand order allows one of the 2 other components, E34 or ER, to be selected.
The electric field waveform is filtered and amplified in a 15Hz-17.4kHz bandwidth and digitized with 16 bits. In addition, the power spectrum is computed with frequency and temporal resolutions that depend on the spacecraft and ICE modes of operation. Simultaneously, data are analyzed by a neural network to detect the occurrence and characteristics of whistler emissions.
In the Burst mode, both the waveform data and the power spectrum, with a 19.53 Hz frequency resolution and averaged over 2.048 s, are stored in the mass memory.
In the Survey modes, only the power spectrum is stored in the mass memory and there are 3 ICE sub-modes. In the first one, labeled , the frequency and temporal resolutions are identical to those of the Burst mode, in the second one  the temporal resolution is increased to 0.512 s and in the third one  the frequency resolution is decreased to 78.125 Hz by averaging over 4 consecutive frequencies.
2.2.4- HF measurements.
The same electric field component used for the VLF range is processed in the HF range. The waveform is filtered and amplified in the 10 kHz-3.175 MHz bandwidth and digitized with 8 bit. The HF data acquisition is performed on 40 data snapshots each 0.6144 ms long and evenly spaced in the 2.048 s elementary interval of the VLF channel acquisition. Individual power spectra are calculated for each snapshot with a frequency resolution of 3.25 kHz and averaged to provide a power spectrum every 2.048 s.
In the Burst mode, the average power spectrum and waveform data for a single 0.6144 ms interval are stored in the mass memory. The selected interval is either the first of the 40 intervals or the one with the maximum total power over the entire HF bandwidth.
In the Survey modes, only power spectra information are stored and there are 3 sub-modes similar to those in the VLF Survey mode, with varied frequency and temporal resolution:  and  provide a 3.25 kHz frequency resolution with respectively a 2.048 s (average over 40 spectra) and 0.512 s (average over 10 spectra) temporal resolution while  provides a 13 kHz frequency resolution (averaging over 4 consecutive frequencies) and 2.048 s temporal resolution.
3- Instrument Performances
Figure 2 summarizes some preliminary calibration results showing the variation of the ICE gain in the frequency range from DC to 3.125 MHz.
Figure 2: Frequency variation of the gain of the electric field channels. In the ULF range the gain applies to the direct measurement of the voltages of individual sensors. From ELF to HF, the instrument provides a differential measurement between 2 sensors.


Unit: CyberQ Wifi
Manufacturer: BBQ Guru
Whilst the first part of this review (Review Part 1) focused on the general operation of the CyberQ Wifi, this part of the review focuses on the Wifi capabilities and its usage. The second part of this review examines the communications protocol and to be fair is a bit geeky (you have been warned!).
The CyberQ Wifi supports two modes of connectivity:
Ad-Hoc - This is the default behaviour of the CyberQ. In this mode, you do not need a router, simple connect your device to the existing SSID (Defaults to - "My CyberQ Wifi" & WPA2 password of "1234abcdef"). Open your browser and connect to http://192.168.101.10. As an aside, both my Android tablet and Windows Phone 7.5 could not connect to the Ad-hoc network, but I had no problem with my laptop and an Android phone.
Infrastructure Mode - This requires an existing Wifi network and a little more effort. On my network, the device connected with no issue and picked up its IP address from my router, which I browsed to using a web browser.
1.) User Interface
When you connect to the device (through a web browser) and you are presented with the home page. This shows the temperature of the cooker, the 3 probes and the fan output. In addition to this the main page allows the user to set the values and update the the head unit. This page refreshes ever 5 seconds (but this can be updated in the units settings)

2分快3高手计划_Smart home, network security take center stage at IoT expo
Int2分快3高手计划e2分快3高手计划rnet 2分快3高手计划of things appli2分快3高手计划cations in the fields of security and smart home solutions are receiving greater attention on the world stage than ever before, and they feature as a highlight of this year's World Internet of Things Exposition that gets under way today.
Security risks related to IoT are increasing, according to Han Yonggang, vice-president of 332分快3高手计划00 Enterprise Security Group, who emphasizes that it's the responsibility of internet security enterprises, smart device manufacturers, software system suppliers and industrial enterprises to uphold IoT security.
At the expo, 3300 Enterprise Security will showcase its latest internet security projects which feature greater network breach detection and protection for the industrial internet and IoT than is currently available.
"IoT-based smart systems are not capable of providing strong security defense due to the lack of a unified standard and sufficient experience of security developers. Invasion of the systems can lead to leaks of users' personal data or even threaten safety," Han said.
As the birthplace of China's IoT industry, the Wuxi city government is paying a great deal of attention to data security and cooperated with 3300 Enterprise Security in July to build a national demonstration center for internet security.
Smart applications across a range of industries will also be showcased at the World IoT Expo.
Renowned Chinese home appliance manufacturer, Haier Group, will showcase its intelligent smart products ranging from refrigerators to air conditioners at the expo based on its U+ smart home platform.
Using the platform, customers can access real-time information about their home appliances on their mobile devices via a dedicated mobile app, allowing them to monitor and control appliances remotely.
"Users are able to enjoy customized and instant services in the age of IoT with Haier," said Li Fusheng, chief information officer of the global information platform of Haier Group.
One example of Haier's latest platform are its intelligent air conditioners, which can compare indoor and outdoor temperatures and humidity changes in real time and then automatically make adjustments while adding purification functions. The appliances can also forecast future weather conditions and environmental information for the specific area where the user is located.
Voice control will be one of the features of Haier's showroom display with fast responses given to spoken enquiries.

Telecoms and broadcasting infrastructure provider Cellnex opted for Synamedia’s virtual digital content manager (vDCM) to support Spanish public broadcaster RTVE in Spain.
Cellnex is moving to a software-only environment with vDCM running on-prem as it goes live across all regions of Spain through the second quarter of 2023. vDCM also supports regional content, enabling RTVE to switch between broadcasting national and regional content using splicing and digital programme insertion features.
Xavi Redon, Product Manager at Cellnex, said: “When we renewed our five-year contract to support RTVE’s TV signal transmission, distribution and broadcasting service earlier in 2023, we turned to Synamedia knowing that its solutions and services will meet our and RTVE’s evolving needs over the long-term.”
Meir Lehrer, Senior Director of Storage and Processing Product Management at Synamedia, added: “Cellnex’s high service level agreement with RTVE means it can’t take any risks when it comes to technology reliability. As the de facto industry standard for content delivery, vDCM has proven in countless deployments that it can meet customers’ requirements for availability.”

The Market Exposure of Three UK Mobile Company Essay
The Market Exposure of Three UK Mobile Company - Essay Example As computed in 2013, the number of registered customers of 3 telecommunication brand across the world is over 23.5 million. Ã There are a number of factors in the internal and external business environment of the telecommunication industry of the United Kingdom which leads to the vulnerability and added costs for the company, Three UK. The changes in the way people use mobile and internet technologies and the development of electronic commerce businesses are seen as opportunities for the telecommunication businesses, including Three UK. Ã Licensing of spectrums is an important business cost incurred by Three UK. The processes of the licensing of frequency bands for the telecommunication operators have high associated costs. The cost of spectrum licensing is the biggest cost incurred by Three UK. The company has to incur the costs of widening the network coverage through more spectrum allocation. For this, the company has set up numerous mobile network towers in various locations in the United Kingdom. For this purpose, either the company has to incur the fixed cost of setting up a new tower or it has to lease these operations to a third party company (Anselin, 2008). In both these cases, Three UK has to invest sufficient amount of money for the ultimate aim of a wider spectrum and network coverage. Also, the company has to continuously ensure that the licensing of frequency bands is acquired in an efficient manner so that the benefits of this kind of limited resource for the telecommunication business can be extra cted in the best possible manner.


An e-mail alias is an e-mail that shares a mailbox with a different email address. For instance, you could have firstname.lastname@example.org and also email@example.com and emails sent to either one of them will be received in a single mailbox. This option will make it simpler and much more convenient to handle a lot of e-mail addresses since you will need to log in only one mailbox if you use webmail as well as configure just one address in an email client on your computer. If you create an alias, you will not only be able to get e-mails, but you'll also be able to send out messages from the various addresses and they will share the Outbox, so you'll still have all communication in one place. Using aliases is a substitute for making use of different mailboxes for a variety of purposes or forwarding one e-mail address to another to be able to control the communication of both in a single location.
E-mail Aliases in Web Hosting
Creating an alias for every email address will be quite simple when you've got a web hosting plan with us. You can do this in the Emails section of the Hepsia Control Panel, used to control the website hosting accounts plus it will take only a few mouse clicks. It is easy to add or delete tens of aliases whenever you want and save valuable time when you take care of the emails for a few email addresses that you use - for instance, various departments in a company or different areas of a web site. If you get messages from multiple email addresses in one email address, but different people must have a duplicate of particular messages, it is possible to combine the aliases with e-mail forwarding and/or mail filters, which could also be set up with Hepsia.


PC TO PHONE
What Is Internet Telephony?
Internet calling is an exciting, new technology, which makes it possible to place domestic and international calls from a personal computer to any telephone in the world.
Using a sound-equipped PC, you can place a call through one of the growing number of call providers, commonly referred to as Internet Service Telephony Providers
When you place an Internet call from your pc, your call is then transmitted over the Internet into local telephone networks and finally, passed on to the regular telephone you are calling. The result is real time, uninterrupted, full duplex voice communication, generally as good as traditional phone calls, and in some cases, even better
Simply put, Internet telephony lets you make real-time voice, fax and even video calls over the Internet. Many small businesses are experimenting with Internet telephony, mainly because it can significantly reduce telecommunications costs.
You might also hear it called voice over IP (VoIP) or voice over the Internet
(VoI). A somewhat synonymous term, IP telephony most commonly refers to voice calls routed over a private intranet or wide area network (WAN), as opposed to the public Internet.
The Basics for PC-assisted telephoning
- Of course, the first thing you’ve got to have is a computer.
Your computer must have a soundcard and speakers, though many prefer plugging in a headset. Without a headset, you may encounter echoing or feedback.
- Your computer must have a good-quality microphone, or your headset may have one instead.
- You’ll need an Internet connection – the faster the better. Don’t even bother trying Internet telephony unless you have a 28.8 connection, and 56K is remarkably better.
- And, finally, you’ll need a telephony program. NetMeeting by Microsoft is by far one of the most popular and is fairly easy to use, but there are many up-and-comer’s that might have features that appeal to you more.
- Making Calls over the Internet
There are some major differences between making a regular phone call and an Internet call.
- First, to make a phone call over the Internet, you need a multimedia computer with at least a 28.8 Kbps Internet connection, a sound card, speakers and a microphone.
- Second, with regular phone calls, your voice travels over the Public Switched Telephone Network
(PSTN), a circuit-switched network that creates a dedicated, and thus high-quality, connection between you and the person you’re calling. With Internet telephony, your voice travels over the Internet, which is a packet-switched network. And since packet-switched networks were designed to carry data (as opposed to real-time communications), calls might experience delays and distortion.
- Third, when making a regular telephone call, you're charged according to the distance and duration of the call. When you make a call over the Internet, distance and duration are not important — your Internet service provider merely charges you a low, fixed-rate price for your Internet bandwidth. For this low price, it's not surprising that you get a lower-quality call than over the telephone.
- Advantages of Internet Calling
- Save Money
One of the greatest benefits of Internet calling is the savings you can realize when you call long distance - sometimes up to 95% off the cost of traditional long distance calls. Because calls are carried over the Internet, rates are determined by the call destination, and not the origin.
- Call Anywhere
Another advantage of Internet calling is that any regular telephone can be reached via a PC. Unlike PC-to-PC technology, such as voice-chat, where both caller and receiver must be online, Internet calling offers the freedom to reach any regular telephone, without requiring any extra effort on the part of the receiver.
- Toll-Free Access
While US toll-free numbers are generally not accessible from outside the US, Internet calling enables users to reach toll-free numbers (800, 888 or 877), from anywhere in the world.
- Call and Surf
If you only have a single phone line for your calls and your computer's Internet access, Internet calling allows you to enjoy both at the same time. Because Internet calling uses your online connection, you can talk and still surf the net!
Telephony Software and Services
you need specialized software to make Internet
calls, there are a number of free or inexpensive
Internet-telephony products. Internet-telephony
software traditionally used proprietary techniques,
which meant that both you and the person you were
calling needed to have the same software, but
some vendors are now adopting a standard protocol.
Still, unless you have a dedicated connection
to the Internet and continuously run your telephony
software, you have to schedule the call ahead
It’s also possible to call someone’s telephone
from your PC through an Internet-telephony gateway
service, such as Net2Phone. Such services carry
as much of your call as possible on the Internet
and use the PSTN to carry only a small part of
the call, allowing the provider to charge relatively
low per-minute rates for long-distance calls.

Not all desktop motherboards have built-in Wi-Fi. The by default built-in Wi-Fi are available in the motherboards of expensive and selected desktops. While the average price range desktops do not offer it but the manufacturer has variants of some motherboards which do have built-in Wi-Fi when extra dollars are paid.
When we talk about notebooks and laptops, their motherboard almost always comes with the cards and thus is enabled. The necessity of a built-in Wi-Fi laptop motherboard is very obvious because these are carried along everywhere, thus a static LAN connection could not be made available to the user everywhere. However, an Ethernet connection is preferred by a PC user because of its stable and fast connection and bandwidth.
Because of slow-speed connection of a motherboard built-in Wi-Fi card, people might not prefer to go such a motherboard. One solution is to buy a router and install and then distribute the broadband to more than one PC. However, this is a costlier solution. Thus, a built-in Wi-Fi card serves better in such a situation.
In this article, we will discuss how you know If a motherboard has built-in Wi-Fi or not. Let’s get started!
What Is A Motherboard With An Integrated Wi-Fi System?
A motherboard with inbuilt Wi-Fi is one that includes pre-configured connection to a wireless connection without the need for extra hardware.
The Wi-Fi modem is often physically connected into the motherboard. These motherboards’ Wi-Fi is situated near the rear I/O panel, with antennae protruding from the chassis.
So, Do Motherboards Include Wi-Fi?
Both yes and no. By default, a typical desktop motherboard, especially a cheap one, does not have built-in Wi-Fi. However, there are a plethora of models available that have built-in Wi-Fi.
How Do I Tell If A Motherboard Has Built-In Wifi?
The built-in Wi-Fi motherboards are those motherboards that connect readily to a wireless network on a plug-and-play feature. Such a Wi-Fi facility is often constructed of modem soldered on the motherboard through wires. One can locate such modem on the motherboard near the back of the I/O panel and the antennae are protruded out of the casing.
Another option is to look at your PC options. Click “Control Panel.” After selecting “Network and Internet,” click “Network and Sharing Center.” In the left pane, click “Change Adapter Settings.” The desktop may connect to a wireless network if Wireless Network Connection is shown as an available connection.
The easiest way is to check the specifications on the manufacturer’s website or in the product handbook.
How Do I Know if My Motherboard Supports Wi-Fi?
The built-in Wi-Fi modem is factory fitted and thus is quality checked and compatibility checked before releasing for the sale in the market. Such motherboards are bound to be supporting Wi-Fi.
However, an extension of a PCI card or Wi-Fi USB Dongle is to be checked for motherboard support. The PCI card needs a dedicated slot which if not available in your motherboard then note that it is not going to work for you.
While a USB dongle used for Wireless internet capturing is usually a plug and play device and the USB compatibility of the motherboard is automatically checked by the operating system when plugged in.
The Windows checks every component installed internally or externally and then loads its driver to run the hardware. But if the motherboard is not compatible with that external component, then the functionality is stopped and a message is popped up that this device is not working properly.
Is Built-in Wifi On Motherboard Better?
There are various advantages which suggest that built-in Wi-Fi on motherboard better.
Portability is the main benefit of a built-in modem in the motherboard. Whenever you want to move, you can move your PC with very ease. So, this mobility allows you to move your desktop anywhere you like and you do not bother about an Ethernet connection.
- Speed is More than Sufficient
The high-end PCs come with a great modem and provide you with a good speed on wireless. This speed is sufficient enough to cater to your internet browsing speed. Even they are very much fine for the commercial users too.
- Great for Office Use
It is a very important benefit of built-in Wi-Fi in a motherboard that it is independent of a Local Area Network Router and thus with very ease one can connect with a router without any tech help. It is beneficial where many PCs are required to be connected with one Internet Connection and it is done with the help of a Router.
Nowadays many offices are converting all their PCs on the built-in modem to get the user free from hassles of wiring and the location bounding. The connection is free of problems when the installation is in question because they are plug and play and only a router password is needed to run the internet on your PC in the office.
Motherboards come with a Wi-Fi modem and yes, we are talking about desktop motherboards here which are slightly expensive than routine PCs. To find such motherboards you need to search a little or actively talk with the high-end PC manufacturers.
It is also to be noted that by adding part you can upgrade your existing motherboard to a Wi-Fi-enabled one. A USB dongle with a built-in Wi-Fi modem in it and antennae furnishes your need to have a wireless facility.
We found that Wi-Fi facility has vast benefits in some cases like multiuser in closed premises. The Ethernet is still the first choice of PC motherboard because of the stationery characteristic of the desktop. However, the manufacturers also manufacture motherboards with built-in Wi-Fi to cater to the needs of the users mentioned above.

Cloudwash is our take on what a connected washing machine should do. But we knew that, to understand and design for this type of device, we needed to have a working technical prototype in-front of us, so we could experiment and experience.
So before creating the Design Prototype, we set out to make a Technical Prototype of adding connectivity to a washing machine. When we started we didn’t know exactly what intervention we would make in the real machine. We thought there might be three approaches:
- To modify and control the main sensor/actuator board in a washing machine, by removing the microcontroller on the board for example and interfacing directly to the rest of the circuitry – the relays, TRIACs, sensors etc.
- To use a machine that used a main board with a connection for external communications (either for a separate controls/display board or for remote diagnostics). If we could work out the communication protocol being used, we could then control the machine through this protocol with a microcontroller.
- To ‘hack’ the buttons, dials and LEDs on the board behind the physical interface of a machine, by using a microcontroller to control relays to fake button pushes and to sense whether voltage was on or off at the LEDs to detect state changes, for example.
Approach 1. seemed quite high risk and the most complicated, albeit with the potential to offer the greatest control of the machine. Approach 3. seemed limited and too ‘hacky’. Approach 2. seemed the cleanest solution, involving only a minor physical intervention, and offered the potential for a good degree of control of the machine. It also meant the majority of the work would be in code (which is easier to iterate over) and that no physical modifications would be needed to the electronics of the machine (meaning we were less likely to damage the mechanics or electronics of the machine or make it unreliable or hazardous in any way).
Approach 2. also felt like the most likely place a manufacturer would make a change to the electronic design within a washing machine if connectivity was added – they would be less likely to change the main board but rather the controls/display board and just extend the protocol between the two boards to include messages relating to the new functionality brought by connectivity. The most that might be needed at the main board would be a firmware upgrade. Most manufacturers already use this approach when creating a range of different washing machines – the main board is the same in each machine and only the controls/display board is adapted to offer a number of board variants for different machines with different user interfaces. For example, some have more buttons and dials to adjust more features on the machine or they might have a display to show wash times.
Having tentatively chosen Approach 2. we selected a suitable machine. One that was low to mid range, had a separate main board and controls/display board, and that also had a fairly basic physical user interface, and thus potentially a simpler or less extensive communication protocol to work out.
We then searched the web and found whatever user and service manuals, external and internal photos and video clips we could for the chosen machine, to gather as much technical detail as possible. General arrangement of components, system descriptions, wash programme data, circuit diagrams etc.
Next we pieced together a rough idea of how the overall electronic system worked within the machine. There was a main board – with sensors and actuators to control the electromechanical parts of the machine such as valves, pump, motor, heating element, pressure switches, temperature thermistor, tachometer and door interlock – and a controls/display board – with a physical user interface made up of controls such as a dial, buttons and LEDs. Each board had a microcontroller, and these talked to each other via serial communication.
Feeling confident we understood our chosen machine fairly well, and with a preferred approach for controlling it, we went out and bought a couple of machines – always good to have spare parts! Once they had arrived we disassembled the upper part of one of the machines to expose the boards and confirm the layout of the components and the general electronic system used.
The next task was to identify the wiring arrangement between the main board and the controls/display board. We used a multimeter to find the grounds on the edge connector of each board. Then using these grounds as a physical reference point we compared against the circuit diagram in the service manual to figure out the connector pin-outs and thus the wiring arrangement between the boards. The relevant wiring was a group of three wires – 5V, Ground and a shared TX/RX (serial transmit and receive).
Now we had the wiring worked out we needed to find the hardware layer of the communication protocol between the two boards. To find this we used a logic analyser to ‘sniff’ the communications being transmitted between the boards, by clipping probes to the connector pins on one of the boards. The logic analyser allowed us to view and record the signals being transmitted between the boards in real-time as we operated the machine. The software for our logic analyser is able to interpret the signals into data – for example, as decimal numbers such as 66, 69, 82, 71 or as ASCII characters such as ‘B’, ’E’, ’R’, ’G’. To do this it must know the type and properties of the hardware protocol you want it to try to match against – CAN, I2C, Asynchronous Serial, SPI etc. By experimenting with different software settings we were able to find the correct protocol – when we started to see intelligible data, we knew we’d found the right one! We discovered the protocol was Asynchronous Serial at 9600 bits-per-second (baudrate), 8 bits per transfer, 1 stop bit, even parity, LSB (least significant bit first) and inverted.
At this point we were doing pretty well and were feeling confident that our approach might actually work out (although we still had to understand enough about the messaging protocol to be able to read and control the machine).
So we moved on to trying to understand this protocol, or at least enough of it to start playing around with the machine. To do this we needed to start recording the data being sent between the two boards and look for patterns in the communication. We had to move beyond the logic analyser that had got us this far and on to a method for capturing the data and logging it back to a computer. The best job for this was a microcontroller. We chose the Arduino platform as it is a microcontroller board we know and love and also works great with our Devshield (which would be needed once we start to add connectivity). We used an Arduino Mega as it has four hardware UARTs for serial communication – we used one for serial-USB communication to a computer for logging and two more to communicate with the two boards inside the washing machine. We needed a few additional components and connectors to interface the Arduino to the washing machine boards, so to make the electronics more robust we moved off of a breadboard and made a small PCB that plugged onto the end of the Arduino.
We now had a way for the Arduino to listen to the communication from both of the washing machine boards and relay everything it heard from one board out to the opposite board. This kept the boards happily talking away (as far as the boards knew they were talking directly to each other over the wires), allowing us to continue to operate the machine fully. But as well as relay the communication from and to the boards the Arduino could also send everything it heard out of its serial-USB port to a computer. The blocks of data were sent as comma separated values so we could save the serial monitor output on the computer as CSV files and open them directly into something like Excel to pore over.
After studying the log files for a while we saw that messages from the main board always started with 201, 42, 33 and that messages from the controls/display board started with 201, 33, 42. These first bytes were then followed by three bytes that described the message type, which in turn were followed by a variable number of bytes that described data for that message – for example it might list the temperature, spin speed, delay and so on if the message was about the wash programme dial changing. Each message ended in a single byte that was the exclusive or (XOR) of all the preceding bytes. This is an example of a simple checksum for detecting errors that may have been introduced during the transmission or storage of the message.
We didn’t understand all of the codes for the different message types, but all we really needed was to identify those that were sent when actions happened that we were interested in – such as the programme dial being changed, the start button being pressed or the wash programme ending. So we singled out the messages that related to a set of actions we wanted to know about and stored the relevant bytes that identified each message type in the memory of the Arduino (EEPROM). The Arduino could then use this block of memory as a lookup table each time a message was received from one of the boards or when a command from the Berg service arrived, to either respond to an action or make the machine do something.
At this point we were able to read and control a reasonable amount of the machine’s operation, to the same kind of degree as the machine’s own physical interface. So we moved on to adding connectivity to the Internet! This is where the Berg cloud services and prototyping hardware accelerated things massively. Using the Devshield and Arduino client library, in a short time we were able to start sending events up to the cloud in response to actions happening on the machine, or receive commands down from the cloud to make the machine do things.
We made a simple web service to capture and store the events coming from the washing machine, and to send commands down to it. This web service was built with Node, Sails (a simple MVC framework), and a MySQL database. The database held a virtual representation of the machine’s state, which was updated every time an action happened on the machine and consequently a Berg event was received by the web service. The virtual state of the machine could in turn be retrieved from the web service at any time by some other application (a web app, desktop app, iOS app).
In our case, this was an iOS app that displayed various properties of the washing machine, such as it’s current programme setting, the wash temperature and spin speed, whether various washing options like ‘spin reduction’, ‘rinse hold’ and ‘extra rinse’ were on or off, and the number of hours it would delay before the wash. The app also showed the stage a wash programme had reached (delaying, washing, finished etc.) and a start time, estimated end time and a progress bar. All of this updated almost immediately each time something happened on the real washing machine. The app also had a button to start and pause/unpause the wash. The web service and database also managed multiple machines and registered iOS devices that had installed the app so that they could receive push notifications, for example when a wash had finished.
To complete the physical modification to the washing machine we made a clear plastic box to contain the Arduino, Devshield and our custom PCB, and mounted this within the top panel of the machine.
I’ll wrap up with something that happened just after we hooked up the washing machine to Berg. It only took an hour or two. We made it so we’d get an iPhone push notification when a wash finished.
And the wash finished. And the push notification came through. And at that moment, it was clear: This is a feature I want!
Let’s recap what made that possible. The main board in the washing machine sent out a message to say that the wash was done. Our Arduino was listening and heard that message. It passed it on to the controls/display board. But it also sent an event up to the Berg service. Berg sent that on to the Node web service which updated the virtual state of the machine in the database and at the same time posted a message to the Apple Push Notification Service (APNs) which in turn sent a push notification to the iPhone.
To do the push notification, we didn’t need to know all the details of how Apple’s servers worked. They just got the notification to where we wanted it. And like the APNs, the Berg service made a whole chunk of the Technical Prototype just work!


Smart technologies have become the preferred choice of city governments for traffic management. These solutions are saving billions in infrastructure costs while improving safety and reliability for citizens.
Smart technologies reduce congestion using the latest Internet of Things(IoT) to optimize traffic flow, and improve safety. These systems integrate hardware, software, and cloud technology in order to dynamically change traffic lights, on-ramp meters for freeways, bus rapid transit lanes and highway message boards.
Intelligent traffic signals can adjust the lengths of green and yellow signals in real time to maximize efficiency, and protect pedestrians and bicycles from collisions. They can also alert drivers of pedestrians and other road users, allow emergency vehicles priority access and support lane changes in an intersection. data rooms providers for international companies
These systems can react quickly to changes in traffic patterns. They can reduce waiting times at intersections as well as fuel consumption and vehicle emissions. These sensors, cellular technologies and other components can be integrated in existing or new infrastructure.
Adaptive Traffic Control can also improve the air quality by reducing engine emission and energy consumption due to idling while keeping cars moving. This is achieved by using a combination of data from cameras, sensor networks and cellular technology to dynamically adjust traffic lights, entry alarms and express bus lanes.
Network connectivity is crucial to ensure that this information reaches its destination. It must offer high bandwidth and ultra-low latency as well as 100% reliability to handle the large amount of data needed by traffic management solutions.

All traffic signals in NOIDA city, a part if National Capital Region (NCR) will run on solar power in a fortnight. Noida Authority and the district traffic police have decided on this as an addition to the current 38 signals powered by solar energy of the total 79 signals.
The decision was taken in the Authority’s board meeting after being proposed about five years back. Around 25 traffic signals maintained by the Authority were powered by solar energy at that time and the decision was taken after the massive grid failure late last month to ensure a “100 percent power back-up arrangement.”
“Frequent power disruption in Noida often leads to non-functioning of traffic signals at various intersections causing inconvenience to both commuters as well as the traffic police. Once all signals are run by solar energy, this problem will be solved,” Sanjiv Saran, CEO, Noida Authority said.
The cost of converting a traffic signal to solar power is between Rs12 lakh to Rs15 lakh, much more than the cost of installing a regular traffic signal. However, in the long run, installing solar panels would facilitate significant savings on energy consumption and costs. “These are easy to maintain and eventually they turn out to be more economical,” Saran said.

The year is 2023 and chargers have gotten incredibly complex and powerful. As I was browsing the web, trying to get my hands on a good one that would allow me to charge any device, I though it deserved an article and some explanations.
USB 1.x, USB 2.x, USB 3.x, USB4
From Wikipedia, these are specifications of "an industry standard that allows data exchange and delivery of power between many various types of electronics".
USB 3 is notoriously known for its blue port. "USB4 mandates the exclusive use of the Type-C connector and USB Power Delivery (USB-PD) specification", says Wikipedia.
USB-C 1 & USB-C 2
Two different revisions of the "new" USB-C connector. The revision 2 comes with newer capabilities (for instance enhanced power delivery). See Wikipedia for more information.
PD (Power Delivery)
The official page says it best:
USB has evolved from a data interface capable of supplying limited power to a primary provider of power with a data interface. Today many devices charge or get their power from USB. USB has become a ubiquitous power socket for many small devices such as cell phones, tablets, portable speakers and other hand-held devices. Users need USB to fulfil their requirements not only in terms of data but also to provide power to, or charge, their devices simply, often without the need to load a driver, in order to carry out “traditional” USB functions.
The USB Power Delivery (USB PD) Specification enables the maximum functionality of USB by providing more flexible power delivery along with data over a single cable. Its aim is to operate with and build on the existing USB ecosystem.
Announced in 2021, the USB PD Revision 3.1 specification is a major update to enable delivering up to 240W of power over full featured USB Type-C® cable and connector. Prior to this update, USB PD was limited to 100W using a solution based on 20V using USB Type-C cables rated at 5A. The USB Type-C specification has also been updated to Release 2.1 to define 240W cable requirements, and with the updated USB PD protocol and power supply definition, this extends the applicability of USB power delivery to a large number of applications where 100W wasn't adequate.
In other words, it's a capability to deliver more power through USB, so as to charge devices.
PPS (Programmable Power Supply)
The USB Power Delivery specification revision 3.0 defines an optional Programmable Power Supply (PPS) protocol that allows granular control over VBUS power, allowing a range of 3.3 to 21 V in 20 mV steps to facilitate constant-current or constant-voltage charging.
iQ3 / PowerIQ 3.0 / PIQ 3.0 (or version 4...)
PowerIQ 3.0 is Anker's version of Quick Charge 4+
Also from another Reddit page:
Power IQ 4.0 means that the device supports USB power delivery 3.1 and all Power IQ 4.0 devices include PPS.
Quick Charge (QC)
Quick Charge (QC) is a proprietary battery charging protocol developed by Qualcomm, used for managing power delivered over USB, mainly by communicating to the power supply and negotiating a voltage. Quick Charge is supported by devices such as mobile phones which run on Qualcomm SoCs, and by some chargers; both device and charger must support QC, otherwise QC charging is not attained.
GaN, GaN 2, GaNPrime
Different generations of Gallium Nitride chargers from Anker, from oldest to newest. Those chargers are generally smaller and cooler (less heat) than other non-GaN chargers. More info on Reddit. Other brands manufacture GaN chargers, not just Anker.
What do buy
Anker USB C Charger (Nano II 65W) USB-C 65W Pod 3-Port PPS Fast Charger, Compact USB-C Power Supply seems to be a good option, price-wise and feature-wise.
For some extra euros, one can get PowerIQ 4: Anker USB C Charger, 735 (GaNPrime 65W) Fast and Compact 3-Port
Ugreen is another great brand I would have considered.
