Even as India gears up to roll out fifth-generation (5G) mobile networks, as many as 90% of Indian consumers surveyed face frequent disruptions or speed issues with their 3G or 4G mobile data connection. Also, due to poor 3G or 4G network quality, every month, two in three consumers surveyed, who use digital payments, have one or more of their transactions disrupted, shows a survey. It also highlights how telcos are still providing 3G networks to customers while charging them for 4G networks. None of the telcos offers any tariff plan for 3G and has plans only for 4G.
LocalCircles, which conducted the survey, says, "...a major concern arises as 92% of consumers of 3G and 4G mobile data services surveyed face either frequent disruptions or speed issues on a regular basis when conducting their transactions or browsing. Almost 66% of the consumers surveyed who use digital payments confirmed that they faced disruption with one or more of their digital payment transactions each month due to poor quality of 3G and 4G networks leading them to use alternate means for such payments."
The survey findings indicate that 46% of 3G and 4G customers are using mobile data services to access the internet for four hours or more each day and 62% are using them to conduct one or more banking or payment transactions every month. The survey received over 38,000 responses from more than 352 districts of the country.
92% of consumers of 3G/4G mobile data services face either frequent disruptions or speed issues on a regular basis
The survey sought mobile data customers' feedback about their top issues when browsing the internet or making a financial transaction using 3Gor 4G or data dongle connections. In response, 48% said they face 'frequent disruptions due to poor network', and another 44% said 'low speed' is their top issue. Furthermore, 4% of mobile customers cited 'other reasons', and another 4% could not say anything.
On an aggregate basis, 92% of consumers of 3G/4G mobile data services face frequent disruption or speed issues regularly when browsing the internet or making a financial transaction, LocalCircles says.
66% of consumers surveyed who use digital payments say that 1 or more of their transactions get disrupted each month due to poor 3G/4G network quality
The next question in the survey sought feedback from consumers who use mobile data to make digital payments about the percentage of their digital payment transactions each month that get disrupted due to poor 3G or 4G network quality. These are digital payments which consumers do not end up making digitally but have to resort to an alternate payment mechanism (cash, cheque, and card).
In response, 5% said that over 50% of their digital payment transactions get disrupted each month due to poor network; 9% said 20%-50% of their digital payment transactions were getting disrupted each month due to it. Around 18% of the respondents said that somewhere between 10%-20% of their digital payment transactions were getting disrupted due to poor network, while for 34% of respondents up to 10% of their digital payment transactions were disrupted due to bad 3G or 4G network.
"On an aggregate basis, 66% or two in three consumers surveyed who use digital payments have confirmed facing disruption at least once or more each month with a digital payment transaction due to poor 3G or 4G network quality," LocalCircles says.
62% of 3G/4G mobile data customers are using their connections to conduct 1 or more banking or payment transactions every month
The next question in the survey asked mobile data customers about the number of times in a month they use their 3G, 4G or data dongle connection to conduct financial transactions like payments or banking.
In response, 9% said they do 'more than 30' financial transactions in a month using their 3G, 4G or data dongle connection. About 12% said '16-30', 24% said '5-15', and 17% said '1-4' times in a month and 34% said 'none', or do their transaction using broadband or DSL or fibre connection, while 4% could not say anything.
LocalCircles says, on an aggregate basis, the poll findings indicate that 62% of 3G or 4G mobile data customers use their connections to conduct one or more banking or payment transactions monthly.
46% of 3G/4G mobile data customers are using them to access internet for 4 hours or more each day
The next question in the survey asked mobile data customers about the time they generally spend each day on their mobile/tablet/computer accessing or browsing the internet via 3G, 4G or data dongle connection.
In response, 15% said they spend 'more than 8 hours' each day browsing the internet via 3G, 4G or data dongle connection. About 31% said they spend '4-8 hours', 25% spend '2-4 hours', and 28% spend 'up to 2 hours' each day. On an aggregate basis, 46% of 3G or 4G mobile data customers are using them to access the internet for four hours or more each day.
Fuelled by an increase in the usage of technology in people's day-to-day life, such as smartphones, tablets and laptops, India's internet user base crossed the 830 million-mark in 2021 while the volume of wireless internet data usage in India has surged seven times, as per Economic Survey of India 2021-22. The report further states that India's average internet data usage has increased to 14.1GB in 2021 from 1.24GB per month in 2018.
As per data from the Telecom Regulatory Authority of India (TRAI), Jio recorded a 10% rise in average 4G data download speed while Vodafone and Airtel's speed increased by 8.9% and 5.3%, respectively. Another recent report by Nokia stated that 4G data traffic in India grew 6.5 times in the past five years, with the highest-ever shipment of more than 160 million smartphones.
This has prompted the telecom operators of India like Airtel and Vodafone to increase the tariff for pre-paid and post-paid subscribers. The last tariff hike was made in November 2021 after a gap of two years. Bharti Airtel, Vodafone Idea and Reliance Jio had increased their tariffs in November 2021 by 20%-25%.
Analysts opine that Indian telcos could further increase tariffs in the range of 20-25% this year. Airtel and Vodafone Idea have already said in their post-earnings call that they are looking at tariff hikes during 2022 to boost their average revenues per user.
Finance minister Nirmala Sitharaman has announced in her Budget 2022 that the spectrum auction for the next-generation telecom network will be completed in 2022 so that the telecom operators are in a position to roll out services by 2022-23.
Last month, Union minister for communications Ashwini Vaishnaw tested a 5G call at IIT Madras. While the government is getting ready to launch 5G, telcos in India are still providing 3G services while charging customers for 4G network.

IoT: Connect Physical and Digital Worlds for New Business Models
The Internet of Things (IoT) represents the vision that every object and location in the physical world can become part of the Internet...
Objects and locations are generally equipped with network, storage and computing capacities and so they become smart objects that can take in information about their environment and communicate with the Internet and other smart objects. So, smart things are hybrids, composed of elements from both the physical and digital worlds.
The key layer connecting both worlds is the connectivity layer. The physical world is not just about hardware, but also more and more software nowadays (think cars). However, a physical thing becomes “smart” when it connects to the digital world. [...]

Legally it technically is possible for the provider to give voice to voicebanks for both software.
However, Vocaloid voicebanks are not allowed to be transfered between the two softwares, so they can only be used with the software they are released for. You would not be allowed legally to use a Vocaloid voicebank for UTAU software, though could continue to use the UTAU voicebank in the software. So while the provider could provide for both, the voicebanks would always be only be able to be used for what they were made for.
Both UTAU and Vocaloid's licensing agreements do not support the transfer for voicebanks into each others software.

Checkout the first smartphone powered by Google's Android operating system. This also happened to be the first hardware device with the Google Trademark on it.
Teaming up with the mobile carrier, T-Mobile, the specifications Google has laid out for devices suggest that manufacturers include cameras for photo and video, and built-in Wi-Fi technology to access the Web at hot spots such as airports, coffee shops and hotels. It also is recommending that the phones be designed to work on carriers’ fastest networks, known as 3G, to ensure that Web pages can be downloaded quickly. Google suggests the phones could include Global Positioning System technology that identifies where people are.
It would be interesting to see how iPhone will respond to this :-D


Many of the core Fedora / Redhat commands and configuration files covered in this chapter can be used in Debian based operating systems, but there are some key differences.
The /etc/network/interfaces File
The main network configuration file is the /etc/network/interfaces file in which all the network interface parameters are defined. The file is divided into stanzas:
The auto Stanza
The auto stanza defines the interfaces that should be automatically initialized when the system boots up.
The mapping Stanza
This stanza maps configuration parameters for an interface depending on the output of a script. For example, on booting the script could prompt you as to whether your laptop Linux system is at home or work with the mapping statement using the answer to configure the appropriate IP address.
By default the much simpler hotplug system is used which assumes that the interfaces will have only one purpose. Typical hotplug configurations simply assign each physical interface with a matching logical interface name (nick name).
mapping hotplug script grep map eth0 eth0 map eth1
In this case interface eth0 is specifically given the logical name eth0, while the logical name for eth1 is implied to be the same.
The iface Stanza
The iface stanza defines the characteristics of a logical interface. Typically the first line of these stanzas starts with the word iface, followed by the logical name of the interface, the protocol used, and finally the type of addressing scheme to be used, such as DHCP or static. Protocol keywords include inet for regular TCP/IP, inet6 for IPv6, ipx for the older IPX protocol used by Novell, and loopback for loopback addresses.
Subsequent lines in the stanza define protocol characteristics such as addresses, subnet masks, and default gateways. In this example, interface eth1 is given the IP address 188.8.131.52/27 while interface eth0 gets its IP address using DHCP.
# The primary network interface auto eth1 iface eth1 inet static address 184.108.40.206 netmask 255.255.255.224 network 220.127.116.11 broadcast 18.104.22.168 gateway 22.214.171.124 dns-nameservers 126.96.36.199 # The secondary network interface auto eth0 iface eth0 inet dhcp
Note: When static IP addresses are used, a default gateway usually needs to be defined. Remember to place the gateway statement in the correct stanza with the appropriate router IP address.
Creating Interface Aliases
IP aliases can be easily created in the /etc/network/interfaces file once the main interface has already been defined. A modified duplicate of the main interfaces’ iface stanza is required. A colon followed by the sub interface number needs to be added to the first line, and only the subnet mask and the new IP address needs to follow as can be seen in this example for interface eth1:1 with the IP address 188.8.131.52.
auto eth1:1 iface eth1:1 inet static address 184.108.40.206 netmask 255.255.255.224
Adding Permanent Static Routes
up option in the appropriate
iface stanza of the
/etc/network/interfaces file allows you to selectively run commands once the specified interface becomes activated with the
ifup command. This makes it useful when adding permanent static routes.
In this example, a route to the 10.0.0.0/8 network via router address 220.127.116.11 has been added. Remember, the
up option and the command must reside on the same line of the stanza.
# The primary network interface auto eth1 iface eth1 inet static ... ... ... up route add -net 10.0.0.0 netmask 255.0.0.0 gw 18.104.22.168 eth1
A complete /etc/network/interfaces file
We can now construct a complete file based on the previous examples we discussed. Just like in Fedora, interfaces can be activated with the ifup and ifdown commands.
# # Debian / Ubuntu # # # File: /etc/network/interfaces # # The loopback network interface auto lo iface lo inet loopback # This is a list of hotpluggable network interfaces. # They will be activated automatically by the hotplug subsystem. mapping hotplug script grep map eth0 eth0 map eth1 eth1 # The primary network interface auto eth1 iface eth1 inet static address 22.214.171.124 netmask 255.255.255.224 network 126.96.36.199 broadcast 188.8.131.52 gateway 184.108.40.206 # dns-* options are implemented by the resolvconf package, if installed dns-nameservers 220.127.116.11 wireless-key 98d126d5ac wireless-essid schaaffe up route add -net 10.0.0.0 netmask 255.0.0.0 gw 18.104.22.168 eth1 auto eth1:1 iface eth1:1 inet static address 22.214.171.124 netmask 255.255.255.224 # The secondary network interface auto eth0 iface eth0 inet dhcp
For more information on the
/etc/network/interfaces file just issue the command
man interfaces from the command line.


Did you know that we hear more with our brains than with our ears? This is an important fact that hasn't been adequately addressed by conventional hearing aids - until now. The Oticon Opn™ is a revolutionary new hearing aid that isn't just an improvement over an old model, rather it's an entirely new design with Oticon's most powerful processor ever. This powerful hearing device addresses the way that we hear and provides its users with better speech understanding.
Challenges For Hearing Aids
According to the Hearing Loss Association of America, approximately 20 percent of Americans experience hearing loss and the rate jumps to 30 percent of those between the ages of 65 and 74. Difficulty with hearing can affect social skills, physical health, family relationships, and even self-esteem.
The main issue with traditional hearing aids is that they make it difficult for users to distinguish sounds in complex environments, where there might be many people or a variety of sounds. The use of directional microphones simply isn't very effective in these situations.
Superior Speech Understanding
The new Oticon Opn is a breakthrough in hearing aid technology as it provides better speech understanding. The system does this through its advanced Velox™ platform, which is a system that processes sound at incredibly high rates of speed to eliminate distracting noise.
Users of the Oticon Opn system report that they require 20 percent less listening effort, which reduces the load on the brain in complex listening environments. They also report that they have a 20 percent greater capacity to recall words and events.
Finally Oticon Opn users state that they have 30 percent better speech understanding, even in the noisiest environments. This study data is sourced from Oticon's website.
These user experiences make it clear that this revolutionary system not only reduces cognitive stress but that it also frees up the brain to concentrate on and perform other important tasks.
Other Innovative Features in the Opn
In addition to better speech understanding, the Opn is distinguished as the world's first hearing aid to be connected to the Internet of Things. The device connects to the internet through what's called "If This Then That" (IFTTT.com) service which allows it to interface with a growing number of devices such as doorbells, baby monitors, and thermostats.
The device's TwinLink technology provides communication between the two ears to provide a more natural-sounding experience. Also, its Open Sound Navigator scans and analyzes sounds in the environment more than 100 times each second so that sound remains balanced and distortion between words is removed.
The BrainHearing™ Technology solution from Oticon, the Opn hearing aid provides an array of innovative technologies that are unprecedented in helping people with hearing loss. This new solution makes it easier for people with hearing difficulties to remain active with the highest level of speech understanding. Experience the Opn – now available at your local Intermountain Audiology hearing clinic.

Open Competition 3 - Electronics and Photonics
Spintronics-Based High-Resolution, Non-Invasive, and Ultrafast Metrology for the Semiconductor Industry
Develop a nanoscale magnetic tunnel junction current-sensing system for integrated circuit inspection that will help maintain the U.S. lead in semiconductors by providing vastly improved metrology for in-process inspection.
Sponsor: Micro Magnetics, Inc.151 Martine St.
Fall River, MA 02723
New manufacturing processes for making semiconductor chips smaller and smaller have introduced new types of nanoscale faults that are buried in the ever-more-complex architectures of electronic integrated circuits (ICs). Before long, the most advanced technologies for fault isolation and failure analysis may be unable to cope adequately with new nanoscale IC features. Prior to ATP, Micro Magnetics had developed both a basic magnetic microscope for profiling current densities in ICs and its sensing element, a device called a magnetic tunnel junction (MTJ). This sensor is based on spintronics, the discipline that exploits the spin properties of the electron to develop a new generation of electronic devices. Micro Magnetics now proposes to develop an advanced system employing a magnetic microscope that exploits spintronics to detect and analyze nanoscale faults and abnormalities embedded in multilayered ICs in this three-year project. The system has three key modules: the motion hardware, the magnetic sensor and electronics, and the control and analysis software. At the heart of this technology is an array of ultrasensitive MTJ sensors that detect the microscopic magnetic fields emitted by an operating IC, which are then used to generate an image of the density and layout of the electrical currents within the IC. Using this scanning MTJ microscope, engineers can noninvasively pinpoint defects down to the smallest units, such as transistors and copper interconnects. The goal of this three-year project is to produce a fully integrated, ultrafast IC metrology system. Fabricating spintronic sensors with a spatial resolution of 20 nanometers and frequency responses of 0-6 GHz entails high risk. Developing a system that can scan ICs at production-line speed is another high risk. Venture-capital firms and private investors consider this project too risky at this stage to merit funding. ATP funding could accelerate the needed research by four years. For semiconductor manufacturers, annual savings from the improved yields attributable to the MTJ microscope system could exceed $1.5 billion. Additionally, this technology could remove a looming impediment to the growth and competitiveness of the $70 billion U.S. semiconductor industry by enabling chip miniaturization to continue.

In our interconnected world, the term “network” has become ubiquitous, encompassing various aspects of communication, collaboration, and information sharing. From the internet that links us globally to the intricate web of devices in our homes, networks play a pivotal role in modern society. This article aims to demystify the concept of networks, exploring what they are and delving into the diverse types of networks that shape our digital landscape.
What is a Network?
At its core, a network is a collection of interconnected devices or systems that communicate and share resources. The purpose of a network is to enable the efficient exchange of information, whether it’s between computers, people, or a combination of both. Networks come in various forms and sizes, ranging from small local networks within homes or offices to vast global networks like the internet.
Types of Networks:
Local Area Network (LAN):
Definition: A Local Area Network, or LAN, is a network that covers a small geographic area, such as a single building or a campus.
Characteristics: LANs facilitate high-speed data transfer and resource sharing among connected devices, which can include computers, printers, and servers.
Use Cases: LANs are commonly used in homes, offices, and educational institutions to connect devices for file sharing, printing, and collaborative work.
Wide Area Network (WAN):
Definition: A Wide Area Network, or WAN, spans a larger geographical area and connects multiple LANs. WANs often utilize public or private telecommunication infrastructures.
Characteristics: WANs enable long-distance communication and data transfer between geographically dispersed locations. They may use technologies like leased lines, satellite links, or virtual private networks (VPNs).
Use Cases: WANs are crucial for connecting offices in different cities, enabling global communication, and supporting services like internet banking.
Metropolitan Area Network (MAN):
Definition: A Metropolitan Area Network, or MAN, falls between LANs and WANs in terms of geographical coverage. It typically covers a city or a large campus.
Characteristics: MANs offer higher data transfer rates than WANs, making them suitable for connecting multiple LANs within a metropolitan area. They may use fiber optic cables or other high-speed technologies.
Use Cases: MANs are often deployed in cities for services like cable television networks, internet access, and connecting various organizational branches.
Personal Area Network (PAN):
Definition: A Personal Area Network, or PAN, is a network that spans a very short range, typically within the immediate vicinity of an individual.
Characteristics: PANs are often created using technologies like Bluetooth or infrared and connect personal devices such as smartphones, laptops, and wearable devices.
Use Cases: PANs facilitate the seamless connection of devices for tasks like file sharing, wireless printing, and connecting peripherals.
Wireless Local Area Network (WLAN):
Definition: A Wireless Local Area Network, or WLAN, is similar to a traditional LAN but uses wireless technologies, such as Wi-Fi, for connectivity.
Characteristics: WLANs provide the flexibility of wireless communication, allowing devices to connect to the network without physical cables. They are commonly used in homes, offices, and public spaces.
Use Cases: WLANs enable convenient internet access, file sharing, and communication between devices without the constraints of wired connections.
Definition: In a client-server network model, devices on the network serve specific roles. Servers provide resources or services, while clients request and use these resources.
Characteristics: This model is common in business environments, where servers store data, manage security, and provide centralized services, while client devices access these resources.
Use Cases: Client-server networks are widely employed for email services, file storage, and database management in organizations.
Definition: In a peer-to-peer network, all devices on the network have equal status and can act both as clients and servers, sharing resources directly.
Characteristics: Peer-to-peer networks are decentralized, with each device having its own resources and sharing them with others. They are often used in small environments where a central server is not necessary.
Use Cases: Peer-to-peer networks are common in small offices, homes, and environments where resource sharing is straightforward, such as file sharing between personal computers.
Virtual Private Network (VPN):
Definition: A Virtual Private Network, or VPN, extends a private network across a public network, such as the internet, allowing users to access resources securely as if they were on a private network.
Characteristics: VPNs use encryption and tunneling protocols to create a secure connection over the internet, ensuring the confidentiality of data transmitted between devices.
Use Cases: VPNs are employed for secure remote access to corporate networks, protecting sensitive data from unauthorized access.
In our interconnected and digital age, networks form the backbone of communication, information exchange, and collaboration. Understanding the diverse types of networks, from the small-scale connectivity within our homes to the vast global web that spans continents, is essential for navigating the intricacies of modern technology. As networks continue to evolve and expand, their impact on our daily lives and the way we connect with the world will only deepen, making them an integral part of the fabric of our interconnected society.


Kutta Radios provides next-generation medium frequency radios to mine operators as a reliable, cost-effective solution to communication and tracking needs. Kutta DRUM® radios use cables, wires, tracks, and pipes to create survivable, redundant communication paths underground that extend for miles. The DRUM® is a wireless medium frequency radio system that works whether mine power is on or off, post-incident, and even through obstructions.
Kutta DRUM® radios use parasitic propagation of a medium frequency signals to send voice and data communications in an underground environment. These signals magnetically couple to metallic items commonly found in the infrastructure of a mine, and allow for voice and data transfers several miles in distance. When proper conductors are present, signals can travel over 5 miles in distance non-line of sight. These point-to-point communications can be carried by conductors such as: leaky feeder cables (powered or un-powered), phone lines, power lines, lifelines, metal pipes and tracks. Conductors that are even buried beneath the earth can continue to transmit medium frequency signals in many scenarios, making the DRUM®Communication System the ideal redundant safety communication system for mine operators.
USE CASE EXAMPLES
The following presentation highlights several possible use case examples of the DRUM® Communication System, including;
- Redundant UHF / VHF Communications
- Survivable Leaky Feeder
- Leaky Feeder Extension
- Bleeders & Hard to Reach Areas
- Mine Rescue
- Rescue Chamber Communications

Stipulations Which Produce the Best Power Amplifiers
The main purpose of employing an amplifier is increasing the amplitude of the input signal. People mainly use amplifiers in various kinds of electronics, and they’re made to perform numerous functions. A lot of the amplifiers used have been built with a particular purpose in mind. The transmitter that is used in radios utilizes a Radio Frequency Amplifier that is inbuilt that simplifies the signal. Below we’ll discuss sound power amplifiers that are intended for use in the loudspeakers.
The goal of using a power amplifier is to use the input signal from the device it originates from and make them good enough to drive loudspeakers. The signal amplitude is the only difference between the signal at the input source and the output.
Moderate power rating plays a vital part in the amplifiers if a person operates them under power evaluations that are adverse. The output signals of amplifiers have some undesired components which are absent in input signals. Such elements are known as distortions. There are various types of distortions out of which the most typical types are inter modulation distortion and harmonic distortion.
The signal level which is needed to give the full power at the amplifier’s output is known as input sensitivity. It’s beneficial if most of the amplifiers had gain whatever the kind of power applied to it. Sensitivity varies considerably and it ranges from 500mV up to 1.5 V or more
The distortion which occurs in the input signal is measured by the total harmonic distortion. It keeps on adding some more signal frequencies to the output which are not there in the input signal. It is measured in the form of a percentage and it varies from 0.001% to 0.1%, and this also applies for the hi-fi amplifiers. An excellent power amplifier should have no sort of distortion.
Each time the input signal changes abruptly such that the output cannot keep pace with it, transient inter modulation stimulation which is also called slew triggered distortion occurs.
A crossover distortion takes place due to power output devices at a push-pull amplifier that works in the Class-AB. It happens in the state and valve designs and is normally caused when equipment turn off suddenly, and other devices take over the half waveform.
The frequency response is the frequency amount when compared to the amplitude distortion in the amplifier. All the signals are amplified equally in the best power amplifier only amplifies all of the signs equally. An amplifier requires a response close to 5Hz to 50kHZ to make sure that all the signals which are audible can handle any minimal modification.
The phase response shows the amount of time that the input signal has been delayed before getting to the output, depending on the signal frequency.


In an effort to build greater transparency between producer and purchaser, Airbiquity and Hitachi Automotive Systems have introduced a revolutionary connected services technology system that would enable electric vehicles (EVs) to operate more efficiently. The infrastructure for EVs such as the electric Leaf that is run by Nissan’s Information and Communication Technology system, (ICT) is provided by this collaborative solution. Nissan’s technological system offers drivers the benefit of tracking down battery charging stations and reaching destinations through routes that would cut down on electric consumption. The system also uses a global cloud maintained by Airbiquity for Nissan that ensures connectivity between drivers and Nissan operators. The ICT that the Leaf uses functions through a data mobilization process that ensures efficiency and makes entertainment available through their cloud-generated technology.
In order to build an effective system of communication, the new technology promises an absolute relationship of trust between the consumers and the manufacturers. The data-dependent system allows for instant information exchanges regarding a car’s battery status, efficiency, tire conditions and other such vital details. This system keeps the automobile producers on their toes so that they may keep a tab on the rate of functionality of their vehicles and make the necessary changes for the next line of cars to be manufactured. On the other hand, the drivers receive constant warnings about low batteries and tire pressures.
The technological revolution that has made access to vital knowledge easy and fast has been tapped by the automobile engineers to enable this project of constant information exchange between consumer and manufacturer. Ford has built its Sync computer system which ensures entertainment for its customers through a voice command-mobilization process that is both easy and state-of-the-art. This computer system also provides security measures such as the 911 operator connection which is highly effective during emergencies.
General Motors (GM) has proposed to inaugurate its new creation, a Buick that would enable video chatting, home surveillance and testing for any damages done to the car. This has been made possible through a collaboration of GM’s Onstar Service and Verizon’s 4G LTE network. Also, Nissan, Ford and GM have built smartphone applications that would operate with their respective Information and Communication Technology systems (ICT.).
The advent of the electric car is a relatively new phenomenon. Therefore, it comes with a price tag that might not be too purse-friendly. The accessories that automobiles like the Leaf or the Chevrolet Volt display, speak of a hard-to-ignore lifestyle cost. This display factor actually works towards fashioning the customer’s taste buds so that he may know what he is looking for and also, what the car is offering him. The car in turn promises to reflect the personality of its owner.
The one problem which arises in a digital era of surveillance is that of compromising one’s privacy. To this problem, the vice president of marketing at Airbiquity, Leo McCloskey offers the solution of cancelling one’s subscription to the ICT service that the automobile companies offer.
So over all, three of the largest car manufacturers in the US have started taking definitive steps towards the betterment of their new age cars. But the transition has not been a smooth one. Most of the car drivers are not avid readers of blogs like Connnected Internet and hence have hardly a clur about all this cloud and connectivity jargon. So in a funny turn of events, some Ford dealers are actually holding quick classes for new owners to explain all the hi-tech features of their new cars. So now, even your car will come with a thick and hard to understand programming manual.

Let H5P content types use external services such as GPT, image generators, messaging services, etc.
Add a way to let H5P content types use external services such as GPT, image generators, messaging services, etc.
Background and basic idea
So, there's nothing that one could do? There is, of course. One could create an extra plugin for a platform that runs H5P. That extra plugin runs on the server. The H5P content type could talk to that plugin, the plugin could communicate to a 3rd party service (that could be hosted on the platform's server or somewhere on the web). That plugin could also take care of credentials safely. That would work, but for the H5P content type to run, it would require that the extra plugin is installed - and available for the platform in the first place. This approach can easily bust the idea of H5P content being able to run everwhere.
Luckily, there is another way. However, it would require to amend the feature set of H5P core and to change the H5P integrations such as the H5P plugin for WordPress or moodle. An H5P content type would find a standardized interface in H5P core where it can send requests intended for another server to. H5P core would check whether the H5P integration offers to relay the request to the target server and use that offer if available. The H5P integration would check whether the author of the content is allowed to use the remote service, provide either server-wide credentials that an admin provided or some user-specific credentials and then send the actual request to the other server. The response (or some error message) would eventually find its way back to the H5P content type.
H5P content type
- "As an H5P content type, I want to be able to retrieve a list of available services that it can talk to in order to determine whether I can use the service and to let the user know if not."
- "As an H5P content type, I want to be able to send a request to some remote server in order to receive the response and react to it."
- "As H5P core, I want to be able to retrieve a list of available services that I can offer to H5P content types in order to satisfy their request."
- "As H5P core, I want to be able to relay a request from an H5P content type to an H5P integration and to return the response or some error message.'
Could be a solution fully integrated into the platform or use some reusable client like for the H5P OER Hub in order to reduce porting effort.
- "As an H5P integration, I want to be able to answer H5P core's query about available services."
- Will check for available services.
- Will check for permission of author/user to use the service.
- "As an H5P integration, I want to be able to relay a request from H5P core to a remote server and to return the server's response or some error message.'
- Will check for availability of service
- Will check for permission of author/user to use the service
- Will check request against template set
- Will add credentials to request if necessary (global credentials set by admin if available, author credentials or user credentials otherwise).
- May need to be able to handle JWTs or similar to support all services.
- "As an admin, I want to be able to configure services that H5P content types can use."
- endpoint (template to be able to replace credentials placeholder in request)
- global credentials (if applicable)
- "As an admin, I want to be able to configure the permissions of platform users to use a service by using the platform's system for rights management."
- "As an author/user, I want to be able to set and edit the credentials required to use the service."
It is very likely that this does not cover all needs, and it is also possible that there's a technical or organizational reason why this will not work (server-side stuff is not my strength) or not be done. That's why I invite the H5P community including H5P Group to share their thoughts here. That means you! Come on, you must be interested if you have read this far!

The big, scary, IPv6 monster #
For those who don’t know, we’re out of IPv4 addresses. Globally. They’re all gone. They even looked behind the fridge for more. So, it’s time to embrace IPv6 (so far as your ISP will allow it!).
My ISP, Internode, gives me a delegated /56 block of addresses. “What does /56 mean?” I hear you all cry? Basically, instead of getting a single public IP address (as was typically the case with IPv4), I have 4,722,366,482,869,645,213,696 publicly-routable addresses to play with.
It’s a visually offensive number. Unfathomably large. I don’t even know which “illion” that comes out to. I tried to frame it as the number of seconds in a century, and it still came out to be a ridiculous number of centuries.
So while some of us are used to the IPv4 dotted-quad notation (192.168.1.1 with a subnet mask of 255.255.255.0), IPv6 goes a bit crazy and calls it the “canonical textual representation format” — one of those terms that just makes me feel warm and fuzzy inside — which looks something like 2001:db8:1234:0000:0000:0000:0000:0001. Thankfully, that can be shortened to 2001:db8:1234::1. For some quality bedtime reading, I suggest checking out the Wikipedia article on IPv6.
Taming, understanding, and eventually, loving the monster #
Thanks to some epic sleuthing (aka Google) I’ve got the following recipe to get IPv6 working both at the edge of and inside my network.
Disclaimer: IPv6 is globally routable! The concept of NAT, and the security-through-obscurity that it provides, does not exist in IPv6. Any IPv6 addresses that you issue to your LAN computers can be reached from the internet — unless you have a good firewall. I take no responsibility if you get all virus’d up.
The first thing we need to do is set our WAN interface’s IPv6 configuration to DHCP6. This will get a /64 address from our ISP and provide a path out to the internet.
The trick here is to use the IPv4 interface (our PPPoE ADSL tunnel) to request our IPv6 connectivity.
Save and apply the changes, then head over to the LAN interface. Here’s where it gets interesting. Set the IPv6 configuration type to Track Interface…
…then scroll down to the IPv6 Track Interface section, and set the IPv6 Interface to WAN and the Prefix ID to 0.
Save and apply, then head to the Status > Interfaces page. This will show you your WAN IPv6, your LAN IPv6, and any IPv6 Link Local addresses.
The next step, of course, is configuring pfSense to issue IPv6 addresses to machines on your network. Head on over to Services > DHCPv6 Server & RA.
While it looks daunting there’s actually very little that needs configuring here:
- Enable DHCPv6 server on interface LAN
- Set the range from ::1000 to ::2000 (or whatever size you want)
- Set the DNS servers
The final step is to configure the Router Advertisements section. You’ll have noticed that the DHCPv6 configuration doesn’t have an option to specify the default gateway — IPv6 does away with the concept of static gateways and, using the Neighbor Discovery Protocol (NDP), announces to the network what the router (aka default gateway) is.
Lastly, at the bottom of the page, check the checkbox next to Use same settings as DHCPv6 server, and click Save
Once again, get your firewall sorted out #
pfSense has a deny-by-default approach to firewall rules. Unless a rule exists to allow the traffic, it’s blocked. This is good!
Unless you’ve a really good reason for allowing traffic into your network on the WAN interface, don’t. Before you get IPv6 configured, take a few seconds to verify you don’t have a cheeky “allow-all” rule on your WAN interface.
Someone pointed out that a glossary of terms would be useful. So, Guy, here ya go:
- IPv6: the 6th version of the Internet Protocol.
- ISP: Internet Service Provider. Telstra, Verizon, BT, etc.
- Subnet mask: a method used to divide an IP address range.
- NAT: Network Address Translation. Wot allows millions of 192.168.168.1 home routers to coexist on the internet without it literally erupting into flames.

We think that with ever more emails and texts – the role for actual voice messages is more important, adding personality and emotion.
But how do you leave a voice message on someone’s mobile without disturbing them with a call? If you ring them, they may answer! How do you leave a voice message for 10, 100 or a 1000 people in one go to save time and money?
CleverVoice enables you to effectively place a voice mail directly onto anyone’s mobile phone, but without calling them. They get alerted with a personal text message from you – and they can pick it up when convenient. They can respond with a variety of options – which you can track online so you know who has had the message – and if they perhaps want a call back or more information sent to them.
The service can be used for one-to-one messages – but really comes into its own when you want to send the same message to large numbers of people – in your voice, at the touch of a button. A simple and effective way to talk to your team, clients or prospective customers.
Save time and money: rather than making calls – send a voice message to a small group or to thousands of people – just at the touch of a button.
Powerful & personal: better than text or email – say what you want to say, in your own voice – but without disturbing people with an inconvenient & intrusive call. Stand out by delivering a more personal and emotional message.
Interactive: you know who has listened to your messages and when – and can track their responses in real-time.
Quick & Simple: easy to use – no software to download. You can send messages to any mobile phone, anywhere in the world.
Convenient: recipients get a personalised alert message which can say who the message is from and the subject (rather than just “you’ve got voicemail”) – so they can choose to listen immediately, or wait until convenient.
Just 3 easy steps to send a message:
You choose who you want the message to go to – using your address book already set-up on CleverVoice, like an e-mail. You can import names and numbers easily from Outlook, or from your database.
Decide what you want to say on a text message sent to the recipients – alerting them to the message you have left.
Record your message, and when happy – send it, and all your recipients will receive an alert – that’s it!
What then? The recipients get the alert, dial in, and pick-up your message. (Recipients can respond if you wish to options you can set up – then you can track who has received the message and their responses).

"A light-emitting diode (LED)... is an electronic light source. The LED was first invented in Russia in the 1920s, and introduced in America as a practical electronic component in 1962. Oleg Vladimirovich Losev was a radio technician who noticed that diodes used in radio receivers emitted light when current was passed through them. In 1927, he published details in a Russian journal of the first ever LED...."

Homes and businesses alike need to beef up their security. This is especially true in areas where they are many people. In the case of a business with a high number of employees or high customer traffic, constant security surveillance is the best thing you can do to your business. There are different types of security cameras to choose from. Thanks to technological advancements, you can now have wireless security cameras. Here are good reasons to have a wireless security surveillance system.
Traditional CCTV surveillance systems often have gaps or inefficiencies. As such, adding a wireless security system takes care of these limitations. Well, most organization prefer using wireless security systems on their own. This is not the best way to go about this. Instead, it is advisable to have a security system that uses both a wired and wireless system and have these two systems work in tandem.
Another benefit of using wireless security cameras is that their installation process is somehow easy and straightforward. On the contrary, wired security cameras require considerable effort for a successful installation. Wired cameras require you to secure both the camera and the cable part. This is not the case with wireless security cameras, which simplifies the installation process. All there is to do is to position the camera in the right place.
Portable and offer extended coverage
If you are looking for portability and a unit that will be able to cover those almost inaccessible areas, get a wireless security camera. Wired systems tend to be somehow impossible to install in areas where you cannot have a cable. This explains why most wired security cameras have blind spots. Using a wireless camera presents an excellent way to address these blind spots leading to enhanced security.
Most wireless security systems have a built-in motion detector. As a result, these sensing units give the cameras a chance to communicating with each other, leading to enhanced security. Another important security feature is that most Bluetooth cameras have a feature that allows them to communicate to a designated third party in the case of a security breach.
If you need to secure your home or business, you cannot afford to overlook the benefits that come with installing wireless security cameras. As a tip, use these cameras with other security appliances to eliminate the chances of having things like blind spots or unauthorized access…

GENEVA, SWITZERLAND – Running from 6-16 March, the Geneva Motor Show, will feature DAB+ radio broadcasts. The idea at the motor show is to encourage and push for technology in cars and this is because of the joint efforts of 3 partners at the show.
At the motor show, visitors will be able to listen to services on air in Switzerland. This is according to industry publication Radio World. Visitors to the show will see how digital radio is integrated into dashboards, with quite a few automotive manufacturers already offering DAB+ as an option or as a standard line fit.
Thanks to Swiss public broadcaster SSR SRG, WorldDMB and the European Broadcasting Union, the car show will demonstrate DAB+ ‘s audio and visual radio services.
There are a number of advantages that come with DAB+ that make it such an attractive addition to cars. The strange thing is, manufacturers have been slow to install the system. This seems to be due to the fact of limited service offers, and in France, for instance, a DAB+ network is all but non-existent.
There are a number of DAB+ stations in Switzerland and now things are changing. Some of the other advantages with DAB+ are no cut-outs in real-time traffic alerts. In fact, one of the advantages that DAB+ retailers and radio stations admire is this better sound, but then a car needs exceptional speakers for this to be evident.
There is still the factor of cost with DAB+ with good color and of course, it can add a significant cost increase to the price of a new car.
We bought a new car with DAB+ but with a smaller screen and this put the price at just a bit more than with traditional radio. Yes, it’s nice to have but I’d wait for DAB+ to be better developed with a better screen before I spend extra on it. I doubt that the motor show exhibitors will be able to convince me to buy just yet.

The State of Oklahoma has invested in technological development with the Oklahoma Broadband Initiative, a statewide effort to increase access to broadband services for hospitals, universities and state agencies.
With demand for broadband access increasing from key institutions in rural areas, Oklahoma launched the initiative to extend services with fiber optic cable, which can transmit broadband signals safely, cost effectively and efficiently over long distances. The Oklahoma Department of Transportation (ODOT) oversaw the design and installation of 1,050 miles of fiber optic cable—over twice the length of Oklahoma.
ODOT worked with multiple firms to design and install the cable system. Garver provided preliminary and final design, construction services, geographic information systems (GIS) mapping and utility mapping for 145 miles, from Ardmore to Ada. Because the majority of the cable's route lay within ODOT right-of-way, close coordination with the agency was required to identify rights-of-way limits and utilities in the fiber optic path.
Utility surveys were performed to enable efficient fiber optic routing over such a long distance. Laying the cable required trenching, plowing, cutting through rock and crossing bridges. Fiber optic cable, which is made of sheathed glass filaments, is unable to make sharp turns, which added another layer of design complexity.
Engineers and construction observers in four Garver offices pooled resources to ensure the project was completed within schedule. "It was definitely a combined effort," said Garver Project Leader Alan Miner, PE. "The project involved interaction with ODOT staff and the program manager on an almost daily basis to ensure we met their requirements in a timely fashion."
Garver designed connections to community anchor sites along the cable's route and created Visio® diagrams for each anchor point to ensure accurate patch panel connections. Along with designing broadband infrastructure, Garver added the rights-of-way, utilities and fiber optic system along the cable route to the state's GIS database. During construction, Garver provided resident engineering and on-site inspection services for 100 miles of cable installation as well as as-built drawings for all 145 miles of cable.
"ODOT's timelines for the design work were incredibly compressed and the inspection process difficult due to the distances of each construction project," said ODOT ITS and Fiber Optic Engineering Manager Alan Stevenson. "ODOT appreciates the professionalism and the cooperation of Garver with these projects."
The fiber optic installation is complete. When the entire broadband network is active, numerous universities, hospitals and emergency response institutions will have greater broadband access and information technology capabilities to better serve their communities.

The most thorough hearing & listening assessment you’ll ever have
Sensitivity to sound
Damage to the auditory system can cause the level at which sounds becomes audible to be higher than normal.
The standard assessment to determine if a person has a hearing loss is called Pure Tone Audiometry, it's what most people are referring to when they describe a hearing test.
This increase in hearing thresholds that a hearing test picks up is what we refer to as hearing loss.
A Pure Tone Audiometry hearing test is used by our audiologists to assess any decline in sensitivity to sound and tests the combined function of the outer, middle and inner ear.
Speech discrimination in quiet
Even in ideal listening environments, some people can struggle to understand speech. There are some occasions when a reduction in a persons ability to understand speech is not caused by a hearing loss but commonly speech understanding in quiet environments declines with uncorrected hearing difficulties.
We assess this area of communication decline using a calibrated phonetically balanced word recognition assessment which enables us to assess any decline in speech recognition.
Speech discrimination in noise
Even for people with no hearing loss, communicating in noisy environments can be a challenge. For those with background hearing difficulties noisy environments can present the most common area of communication challenge.
Normally hearing people usually need speech to be just one or two decibels above competing sounds to make out enough to follow a conversation but where common types of hearing impairment occur it is not unusual to see that gap increase significantly.
It is essential to assess this common area of communication decline if the correct technology approach is to be identified by your audiologist. We use a sophisticated Speech in Noise assessment to get to the bottom of any difficulties you may be having in environments with competing background noise.
Comfort and tolerance to background noise
A common myth is that people with reduced ability to hear can more easily withstand louder noises. In fact the opposite is more often than not true.
Modern hearing aids are highly efficient at reducing unwanted background sounds but perhaps the single most common myth in hearing correction is that these Digital Noise Reduction (DNR) systems improve speech understanding in noise, they don't.
Our approach is therefore to use as little DNR as is needed in order to achieve comfort without reducing speech understanding further.
We use an Acceptable Noise Level assessment to assess the cognitive load, or effort, you have to use in order to try and cope with annoying sound sources.
Response to Hearing Correction
It is very difficult to say what the immediate effect of hearing correction will be on any given patient. There are many factors that play a part such as how long the hearing loss has been uncorrected for.
The rehabilitation process is driven in part by a patients neural plasticity, how fast the brain can rewire and learn new to do new things, and we can only assess this by trying you with the correct levels of hearing correction applied. The good news is that most people who might initially struggle will usually make solid improvements in time.
We assess this area of communication decline by programming your ideal sounding hearing solution and then assessing its immediate performance.

Noise Reducing Fence – We supply quality Acoustic Fencing for all commercial and domestic applications. Contact us on 0116 2725908 and talk to an Acoustic Consultant now.
- Excellent noise reducing properties of up to 30dB
- Durable timber structure incorporating acoustic infill
- Manufactured in standard panel or bespoke
- Airtight for acoustic performance
- Reducing traffic noise from that busy road
- As a noise barrier between you and your noisy neighbours
- Reducing noise nuisance from school playgrounds and parks
- Noise reduction from sports areas and playing fields, i.e football pitches and tennis courts
Noise reducing fencing could typically achieve a noise reduction of up to 30 dB which would make quite a considerable difference, however this would depend on the surrounding geographical conditions to your garden, for example, if you have a noisy road nearby which is causing you a problem with traffic noise then it would depend on the distance from your garden to the road and generally the further away the noise source is from the receiver the higher the fence requirement.
Calculating the height of the fence and its criteria is not straight forward and we would strongly recommend an acoustic survey to be carried out prior to installation, read more about our acoustic surveys specifically for fencing here.
We carry out noise testing throughout the UK and would be happy to discuss your requirements, so call us if you have any questions or you would like to discuss things further.
