Thus far, it's the only mic we've tested to offer multiple DSP settings, and a DSP-free setting, but there are other mics that offer multiple mic patterns—the MV51's is fixed to cardioid, which is the typical pattern for USB mics.
Shure also includes the aforementioned gain level slider. The DSP for each setting will change with the gain levels, and the flat, DSP-free setting would be something of a letdown if you couldn't also adjust the gain to the proper setting. Having so many presets onboard—and the ability to ignore them all and simply record with a pure signal—is not a common trait in USB mics. Hats off to Shure for making such a versatile tool.

Currently the SMeART consortium is preparing so called guidelines in order to support SMEs during their transformation process towards „Smart engineering companies“. Professor Leisenberg is manager of the project
The SMeART project team with Prof. Leisenberg (in the centre)
For the above guideline publication we are trying to find valid scientific descriptions and definitions for related terms. In this regard I have found an interesting paper: „Smart manufacturing systems for Industry 4.0: Conceptual framework, scenarios, and future perspectives“ (see reference). Here, the author would like to take the opportunity to introduce some thoughts of this publication:
In an extended introduction the article describes the environment very detailed: “…new
technologies are nowadays penetrating manufacturing and serving as key enablers for the
manufacturing industry to address current challenges such as increasingly customized requirements,
higher quality, and shorter time-to-market by converting manufacturing systems onto a smart level.
For example, by being deployed sensors (e.g. machine tools), manufacturing equipment can self-sense,
self-act, and can also communicate with each other”. In addition it says that ” it is possible to capture and share real-time production data, which could be used for rapid and accurate decision-making. In particular, the connection of physical manufacturing equipment and devices over the Internet together with big data analytics in the digital world (e.g. the cloud) brings about are revolutionary production pattern – Cyber-Physical Production Systems (CPPS)”.
Section 2 of the above paper presents a framework for Industry 4.0 smart manufacturing systems. In Section 3, a number of demonstrative scenarios are presented. Section 4discusses the current challenges and future perspectives. Section 5 concludes the reviewed paper.
The proposed framework of Industry 4.0 smart manufacturing systems in which research topics are categorized into smart design, smart machining, smart monitoring, smart control, smart scheduling,and industrial applications consists of:
* Smart design
* Smart machining. In Industry 4.0, smart machining can be achieved with the help of smart robots and various other types of smart objects that are capable of real-time sensing and interacting with each other.
* Smart monitoring
* Smart control
* Smart scheduling
* Industrial applications
In chapter 3 DEMONSTRATIVE SCENARIOS are described:
* For Smart Design a UX-based Personalized Smart Wearable Device: With this example customers become more actively involved in the product design process to co-creating personalized products with better UX and satisfaction, which is known as the manufacturing paradigm of mass personalization
* For Smart Machining CPS-based Smart Machine Tools: CPS-enabled smart machine tools are used for producing physical products. CPS are capable of bringing together the virtual and physical worlds to create a truly networked world in which intelligent objects communicate and interact with each other
* For Smart Monitoring Energy Consumption Monitoring: A cloud-based smart control system is proposed which takes CNC control for example to illustrate the key concepts. All of the non-real-time tasks will be executed in the cloud. Machining jobs are scheduled and distributed among connected machine tools taking into account their capability and availability, which are treated as local manufacturing resources. A local operator is also able to start a machining by logging a part programme. The cloud is able to interpret the part programme no matter it is in G/M code or in STEP-NC.
* For Smart Scheduling – Machine Scheduling in Smart Factories: Based on smart machines, smart monitoring (e.g. energy consumption monitoring), and smart control system from cloud, smart machine scheduling can be achieved. Machine scheduling is a classical problem that has been studied for decades, and in the context of Industry 4.0, there are a number of new characteristics and requirements. In Industry 4.0, machines are endowed with a certain degree of intelligence and can communicate with each other by being deployed various sensors and wireless communication devices (e.g. RFID).
* For Industrial Implementation – Smart 3D-scanning for Automated Quality Inspection: The inspection process begins with scanning an object and creating 3D files of points, called point clouds, as raw input. By means of filtering process, unreliable range measurements (outlier) are removed. Then point clouds are analyzed and compared with initial design. Finally, the results are visualized with different colors to show the degree of quality of each segment of the part. Data gathered from each process is stored inbig data storage. By using big data analytic tools, control chart, mathematical statistics knowledge and intelligent algorithm, the data can be processed to provide valuable information for manufacturers and customers. This system is also connected to the internet to provide real-time quality data of the processing parts or finished workpiece online for customer access.
Finally, the paper focusses current challenges and perspectives and provides hints on future of real-time data collection in manufacturing systems.
Importand contributions of this paper, that might be applied for the SMeART project, are as follows:
* Systematic framework for Industry 4.0 smart manufacturing systems is proposed, covering a number of relevant topics such as design, machining, monitoring, control, and scheduling. This framework provides an important reference for academia and practitioners to rethink the essence of Industry 4.0 from different perspectives.
* The paper reviews the key perspectives under the proposed framework. Insights for the future research directions of data collection, virtualization, and decision making are provided. It can provide the SMeART project with some insights into implementing Industry 4.0 and smart engineering.

MMIC amplifiers based on both high-electron mobility transistors (HEMTs) and
heterostructure bipolar transistors (HBT) have recently been demonstrated with
with useful levels of gain above 600 GHz. Developed under the DARPA Terahertz
Electronics Program, they are likely to power the components and subsystems of a
new generation of submm imaging radars, telecommunications systems, and spectrometers.
The author will describe NIST efforts to improve the accuracy of power, gain, and s-parameter
measurements on such components, from 100-700 GHz.


The United States Coast Guard maintains radio receiver stations for communication between Coast Guard units, Coast Guard units and early politics entities, and Coast Guard units and the general public. Most communications take place on the VHF marine bands. For long-range communications with aircraft, Coast Guard stations use shortwave single-sideband communications. Weather and base hit of navigation forecasts involve fax ampere well as other modes over shortwave and mediumwave transmissions. According to the NTIA, the Coast Guard is the seventh-biggest user of radio spectrum in the United States. The U.S. Coast Guard maintains a network of VHF radio stations at its shore stations and on cutters and boats, a well as stations of the U.S. Coast Guard Auxiliary. In addition, the Coast Guard maintains a chain of high frequency ( HF ) and medium frequency ( MF ) radio stations that provide communications in the Atlantic and Pacific oceans, the Gulf of Mexico, and the Caribbean Sea. Coast Guard VHF Radio stations are presently being upgraded through the Rescue 21 program to meet the US obligations under the Global Maritime Distress Safety System .
history of Coast Guard land stations [edit ]
The first gear Coast Guard land stations were established after 1924, when the Coast Guard ‘s mission expanded. The beginning land station was at Rockaway Point Coast Guard Station, located at Fort Tilden, New York ; and the network expanded to Nahant, Massachusetts ; New London, Connecticut ; Cape May, New Jersey ; Cape Henry, Virginia ( with the birdcall sign NMN ) ; Fernandina, Florida ; Fort Lauderdale, Florida ; Mobile, Alabama ; San Francisco, California ; San Pedro, California ; Port Angeles, Washington ; and Anacortes, Washington in the 1930s.
The network expanded even further in the 1940s, adding radio station NMH in Washington, D.C, among others. however, in the 1970s, the increasing use of automation caused the phone number of stations to contract. In 1976, for exercise, NMN ( then at Communication Station ( COMMSTA ) Portsmouth ) assumed the duties of NMH in Washington, and took over distant operations from Miami in 1993, Boston ( NMF ) in 1996, and New Orleans in 1998. With the introduction of the computer-assisted Rescue 21 system, the ability of the Coast Guard to provide coverage on the marine VHF dance band in marginal areas has increased .
current Assignments [edit ]
There are respective Coast Guard radio stations responsible for operating more than one station or with a across-the-board sphere of province. communication Command ( COMMCOM ) is located on the site of U.S. Naval Security Group Northwest ( near Newport News, Virginia ), and has a staff of approximately 100 people. COMMCOM provides technical foul communications aid and discipline to other Coast Guard units. It operates the postdate stations :
- COMMCOM Chesapeake, Virginia: call sign NMN (directly)
- RCF Miami, Florida: call sign NMA (remotely)
- RCF Boston, Massachusetts: call sign NMF (remotely)
- RCF New Orleans, Louisiana: call sign NMG (remotely)
- RCF Point Reyes, California: call sign NMC (directly)
- RCF Honolulu, HI: call sign NMO (remotely)
Communication Command Detachment Kodiak ( COMMDET Kodiak ) reports to COMMCOM and is responsible for communications in the Alaska area of operation and operates
- COMMDET Kodiak, AK: call sign NOJ (directly)
Modes of infection [edit ]
These stations broadcast navigation and nautical condom messages through several means, including Navigational Telex [ NAVTEX ] transmissions on 518 kilohertz ; facsimile transmissions of National Weather Service charts ; one sideband transmissions ; and Simplex Teletype Over Radio SITOR narrow-band direct-printing broadcasts. In the 1960s through the 1980s, these transmissions were broadcast know, with the time interval bespeak of “ Semper Paratus ” ; however, now, using Voice Broadcast Automation ( VOBRA ), a computerize voice ( “ Perfect Paul “ ) reads the voice messages. NAVTEX transmissions are identified by the survive letter of the callsign of the station. Each place transmits a NAVTEX broadcast six times a day, including two rebroadcasts of the general calculate. A NAVTEX broadcast includes nautical navigation warnings, weather forecasts, ice warnings, Gulf Stream locations, radio navigation data, rescue messages, and marine advisories. Each place has 2 NAVTEX transmitters. Besides air messages, Coast Guard stations handle direct traffic between aircraft, cutters, boats, and prop up stations on VHF, MF, and HF frequencies, including the HF Data Link encrypted e-mail system and Digital Selective Calling ( DSC ), which uses radio receiver telephone to send digitally encrypted signals to either one recipient or a group or receivers .
Concerns [edit ]
The use of the radio spectrum by the U.S. Coast Guard, like all U.S. Government agencies, is assigned by the Department of Commerce ‘s National Telecommunications and Information Administration ( NTIA ). specific frequency allocations are handled by the Interdepartment Radio Advisory Committee .
The function of the Auxiliary [edit ]
Coast Guard Auxiliary stations are privately owned stations that have been offered for consumption of the Government and have been approved by the Coast Guard. They may be on the nautical VHF band or use HF communications. In addition, many Coast Guard Auxiliarists are stipulate radio watchstanders at existing Coast Guard stations.

Coast Guard call signs [edit ]
Most Coast Guard land-based VHF radio receiver stations do not use three-letter predict signs as the larger communications stations do ; alternatively, they identify themselves by the bodily process name, such as “ Sector Baltimore ”, “ Station Washington, D.C. ( or Station Washington ) ”. All Cutters ( CG vessels 65 feet in length or greater ) have four-letter international radio call signs, such as USCGC Citrus /NRPQ. Cutters normally identify themselves as “ Cutter ( identify ) ”. Boats identify themselves with the last digits of their registration number, for example, a Defender-class boat with the adjustment 25123 would be “ Coast Guard 25123, while a 41-foot boat would be “ Coast Guard 41345. ” Aircraft identify themselves by their issue. A numeral beginning with “ 15,17,20 ” is a HC-130 ; “ 21 ” is a HU-25A/C/D ; “ 23 ” is a HC-144A ; “ 60 ” is a MH/HH-60J/T helicopter ; “ 65 or 66 ” is a HH/MH-65 ;. Auxiliary aircraft and ships identify themselves as “ Auxiliary # # # ” .

IODA's APIs allow users to query for outages detected by IODA. IODA detects outages using three data sources—Internet Background Radiation (IBR), BGP, and active probing. For more information about the detection methodology see the Help page.
IODA has been monitoring and detecting Internet outages since July 2014. IODA's APIs have been designed to allow users to query for subsets of outages that they are interested in. We currently offer two APIs to access these outages.
The Event API allows querying for outage events detected by IODA. An outage event is an instance of a macroscopic Internet outage affecting the edge of the network. Each event has well-defined fields, such as the outage's start-time, duration and other fields, as defined in the Common Outage Data Format. Events are detected by IODA when there is a significant drop followed by a subsequent increase in the timeseries of an IODA data source for a group of addresses (such as addresses belonging to the same geographic region or Autonomous System).
The Alert API allows querying IODA's outage alerts. An outage alert signifies the beginning or end of a potential outage event. However, unlike events, alerts have no duration and are instead generated by IODA when there is a significant drop (or subsequent increase) in the timeseries of an IODA data source for a group of addresses (such as addresses belonging to the same geographic region or Autonomous System). IODA's help page contains more details on how IODA generates alerts for each of its data sources.
Most users' use-cases will be addressed by the event API since this API returns outage data that has been processed to remove some sources of noise from the underlying alerts that IODA generates. However, the event API itself internally uses the alert API.

This feature was discontinued in SecurityKISS
Octopus Tunneling allows forwarding traffic from one tunnel to another.
The tunnels from which data is forwarded may belong to one user (identified by client ID and individual certificate) or to two different users. In order to avoid confusion we are going to call them peers.
Octopus Tunneling is not confined to one-to-one links. You can define as many peers as you want and in this way create a network of trusted devices and users who can see each other as if they are in the same local network. It has the following implications:
Peers can address each other by private IP addresses in the same way as computers in your home network. These addresses like 192.168.x.x or 10.10.x.x are non-routeable on the Internet what gives additional confidence that the transferred data will not be compromised
Firewalls and NATs become invisible between peers
Services that require direct IP access like FTP, web servers, games, remote desktop can be set up on one PC and are accessible by other peers
To some extent it is possible to emulate ethernet LAN (however IPX/SPX protocol is not supported)
Needless to say, all data is encrypted and Octopus Tunneling inherits all benefits of regular SecurityKISS Tunnel.
How it works
This solution goes back to the roots and allows configuring the real VPN (Virtual Private Network) for a group of users.
Normally SecurityKISS Tunnel is used to create encrypted one-to-one links between clients and the server. On the server client's IP address is replaced, data is decrypted and sent to destination.
Although very useful it distorts the VPN original idea which is to allow clients safely connect to each other and feel like at home even if they are geographically dispersed.
Since SecurityKISS users generally do not know each other, we can not permit such direct links by default. Instead we authorize individual users to request and approve forwarding between selected clients so that they have full control over who can be linked with them directly via Octopus Tunneling.
In Figure 2 client 1 and client 3 become peers. Both peers must agree on forwarding. Only then the link is created.
Apart from securing the link between two or more peers, Octopus Tunneling has a critical advantage over alternatives. While many ways exist to set up a safe point-to-point connection between nodes with public IP, Octopus Tunneling makes it possible at all if both peers are behind NAT/Firewall.
In Figure 3 direct communiction between peers is not possible because both peers are behind NAT/Firewall
With Octopus Tunneling firewalls are transparent because both underlying connections are initiated from the peers. There is no need to set up port forwarding or configure firewalls in any other way.
SecurityKISS solution is unique because in contrast to others it allows end users to decide who can join their network. SecurityKISS users become administrators of their own Virtual Private Networks.
The administration is straightforward - you only need to request or accept forwarding to the selected client ID on the selected server in the Client Panel.
SecurityKISS users and customers get access to Client Panel in the account activation email.
Once you can log on to the Panel see Octopus Tunneling Forward Configuration Manual for details.


The channel is the basis of wireless communication. The deeper the understanding of the channel, the higher the efficiency of coding and modulation, and the closer to the theoretical line of Shannon's theorem, and the multi-channel communication system makes the channel very complicated. More than 8 channels of MIMO technology have a very obvious effect on improving spectrum utilization, and will be the key technology for 5G scale applications. Currently, we plan to test 10 types of scenarios, and we will test more than 20 types of scenarios in the future, including shopping malls, airports, large stadiums, open large squares and beaches, and high-speed rails moving at speeds of 200 to 300 kilometers per hour. Channel.
Through the continuous breakthrough of 3G and 4G, China's overall strength has been greatly enhanced in 5G research. Recently, at the "3rd China Information and Communication Test Technology Conference" held in Shanghai, the reporter saw the industry's first officially launched MIMO parallel channel acquisition and channel simulation platform (currently implementing eight channels). With this platform, the industry can The understanding of 5G key technology MIMO has been raised to a new level. With the curiosity about the difficulty, role and purpose of the MIMO parallel channel acquisition platform and the next use plan, the reporter interviewed Yang Lan, director of the Shanghai Wireless Communication Research Center, which developed the platform.
Why do parallel eight-channel channel platforms?
The industry has formed a basic consensus on multi-channel technology (MIMO). Compared with the single-channel and dual-channel applications of large-scale applications in the past, 8-channel MIMO technology has a very obvious effect on improving spectrum utilization, and will be applied to 5G scale. Key technology.
The industry is also launching related equipment. For example, ZTE has launched a 64-antenna MIMO device and actively promoted the MIMO device to enter China Mobile's 4G+ network. Li Yue, president of China Mobile, also said at the World Mobile Congress Shanghai Exhibition at the end of June. In order to speed up the introduction of 5G technology such as 3D-MIMO in 4G networks; in April this year, Datang Telecom launched the 256-antenna array device to push MIMO technology to a new level. At the same time, however, the channel model of MIMO is built by single-channel simulation. The real channel situation when multi-channel is parallel has not been measured.
"Channel is the basis of wireless communication. The deeper the understanding of the channel, the higher the efficiency of coding and modulation, and the closer it is to the theoretical line of Shannon's theorem, and the multi-channel communication system makes the channel very complicated." Yang Wei said, "The 5G research has stipulated many new scenarios, including high-speed mobile high-speed rail, subway, large stadiums and crowded gathering places. These scenarios are complex and challenging, and MIMO is needed to support reliable communication. However, if the understanding of the multi-channel channel is only theoretically derived and there is no measured data, it cannot be truly commercialized. Because the terminal or base station equipment should be verified in the experiment, after the actual verification, our understanding of the multi-channel communication channel will be improved. At a new height, we can confidently push it into commercial use."
Four challenges in platform construction
Why did this parallel eight-channel channel test platform take two years before and after launch? Yang Lan told reporters that the platform was realized by integrating eight single channels. In the past two years, they mainly solved four challenges. .
One is the challenge of multi-channel calibration. Unlike a single channel, how to maintain the consistency of each channel in multiple channels is a common problem encountered in the industry. Even if the product is produced by the same company, the difference between the eight channels due to the small difference in hardware often leads to the difference of different channels. Only the channel difference generated by the hardware difference is removed in advance, and the obtained data will be the data of the spatial channel. So multi-channel calibration is the first challenge.
The second is the challenge of synchronizing the two channels of â€œreceivingâ€ and â€œtransmittingâ€. In the test, it is necessary to ensure that all signals are sent at the same time and are received at the receiving end. Because the distance between the antennas is on the order of centimeters, the time difference between the signals is within 100 picoseconds. Therefore, only when the synchronization accuracy is less than 100 picoseconds, the time when the same signal reaches different antennas can be distinguished, and the synchronization precision is very high. "We use the high-precision cuckoo clock system plus our own synchronization algorithm to achieve an accuracy of 30 picoseconds." Yang Wei said, "Using picoseconds in optical communication, as long as milliseconds in wireless communication." Level is fine."
The third is to test the challenges of data storage. The 8 channels have 8 transmitters and 8 receivers, and each transmitter has 8 receivers to form a matrix transceiver. In the actual measurement, 64 channels of data will be generated. Therefore, 64 channels of data are stored and the amount of computation is very large. "We use a ZERO COPY technology of the computer, which is zero-copy technology, which saves storage time. The data can be stored in real time without compression. This data stream technology ensures that the data measured on site can be stored completely and completely. "Yang Yang thinks this is very important. "It's like taking a complete picture of the data. It's like taking a high-resolution photo. The higher the accuracy of the photo, the more details you can see. The understanding of the channel will be The deeper."
The fourth is the challenge of matrix computing. Since the single-channel 1&TImes;1 becomes the 8-channel 8&TImes;8, the matrix data makes the amount of computation soar, so a parallel post-processing software is needed. "We developed together with Teacher Yin Xuefeng of Tongji University to extend the SAGE algorithm to parallel, from the original one to the other, so that the correlation between the channels and the related information hidden in the matrix can be extracted. This is more complicated than the original single-channel test, and it is more profound than the original understanding of multi-channel systems.â€ Yang Wei believes that because the details and analysis are more accurate, the industry can use these advantages of multi-channel and do more. accurate.
Complete multi-scenario testing and open shared data
At present, equipment manufacturers MIMO product prototypes have been launched, but there have been bottlenecks in channel modeling. Each manufacturer also uses different methods to verify its own technology, but no one has fully verified the products in a real environment. Yang Wei told reporters that he plans to open the measured data to the research community. On the one hand, he will give back the support of the entire research community. Second, he hopes that they will have more requirements and feedback on these data in order to serve them more. Because only the data has more requirements, the data is more valuable. And now there are only measurement data of different scenarios, but in the channel modeling and the impact of the channel on various devices and terminals, we must also promote with the more advantageous enterprises in China.
â€œThe very good thing is that there is already a prototype of the product, and then we have to go through the process of painful verification, iteration and correction. Our platform can make the original enterprise take time and effort to test in different scenarios, and then simplify the process of modifying the laboratory. "Yang Wei said, "because we will move the data of the various scenarios we have tested back to your lab, making the iteration and verification of the enterprise more efficient, and the problem is found in the test and then the device is withdrawn. The cost is very high, and the test plays an important role in the process of industrial maturity. Whoever solves the problem before the sale, the less trouble in the future, the greater the contribution to the industry."
According to reports, the current planning of 10 types of scenarios will be tested in more than 20 types of scenarios in the future, including shopping malls, airports, large stadiums, open large squares and beaches, and high-speed trains at speeds of 200 to 300 kilometers per hour. The channel in high speed movement. The impact of weather changes on the channel will be further measured, such as rainy days and sunny days. These data can allow researchers to get all kinds of outdoor data without leaving home, which is equivalent to having done field testing to achieve "outdoor testing indoors." â€œWe moved the real scene of the outdoor test back to the lab and played back the data, which is basically the same as walking around the site with your device and terminal.â€ Yang Wei said, â€œIf you find an error in the drive test. Researchers can continually replay to study the core causes of this error."
Promote the development of high frequency and more channels
The MIMO parallel channel acquisition and channel simulation platform now uses the frequency band below 6 GHz, which is also the main frequency band of China's 5G technology research and test. Yang Lan expressed the hope that the data and model of this platform test can be promoted to the 5G technology research and test.
In the future, this platform will expand to more channels and higher frequency bands. Yang Wei said that the next step is to expand the 8-channel test to 64 channels, but the work is still in progress and there is no mature solution. It is imperative that the industry use the data obtained by testing and analyze the data so that the work done before is recognized by the industry. Then analyze whether the data of these channels is enough to understand the multi-channel. "Perhaps there is not much difference between 64 and 8 roads, because the fineness of resolution has reached a certain level, and there is no new secret discovery, but this is also related to the scene. The next step is to improve our capabilities. Make a comparison." Yang Lan said.
Yang Wei said that in the next step, we also want to expand upward in the frequency band, reaching 28G or even more than 70 G, and finally can cover within 100G. At present, the 8-channel platform has been set up, and the high-frequency expansion is mainly to improve the software, time precision and data storage. "We are working hard in this direction, but if we go down, we need industry colleagues to give us ideas and help us improve our platform capabilities." With a scholar's attitude, Yang Lan issued such an invitation to the industry.

The government of Barbados signed a historic contract on January 5, 2016 for the implementation of Government’s Wide Area Network (WAN). The WAN was conceptualized to serve as a key infrastructural element and a catalyst for Government to aggressively implement its proposed e-Government programmes.
Alyson Forte, Permeant Secretary, in the Ministry of the Civil Service stated that the WAN “has the ability to transform the public service, opening up many services and opportunities for government and the private sector.” Its introduction is expected to play a crucial role in the execution of the Human Resource Development (HRD) Strategy currently being undertaken, through grants from the European Union (EU).
In addition, the Wide Area Network will aid in Knowledge distribution through formal and informal networks. Access to timely and reliable information is critical to decision making, policy formulation, and programme implementation, and is essential to business whether in public or private sectors. The timely arrival of the WAN will greatly facilitate these tasks.
The WAN has already been installed at thirty (30) of the thirty-two (32) sites identified for phase 1. Currently twelve (12) WANs are utilised within the Barbados Public Sector. Having been developed independently, no connectivity currently exists between them. They will eventually be replace or integrated into the new government WAN. This process has already started with the largest network, the Financial & Human Resource Network (SmartStream) migrating to the new high-speed WAN. Martin Keogh, General Manager of Digicel Business indicated that the specifications of the network, “are of such a high standard, that it is regarded as Cisco’s most advanced and powerful network deployed anywhere in the region.”
The network is expected to provide the following benefits:
• High-speed inter-agency connections for greater communication and service delivery efficiencies;
• Internet gateway for Government which is secure and cost effective;
• Extensive utilisation of internet protocol (IP) telephony has resulted in cost savings, of over 50% on Governments telecommunications bill in agencies already utilizing the network which hosts the new Voice over internet protocol (VoIP) phone system and Dedicated Internet Access (DIA) provided by Digicel. This is expected to be replicated across the public service.
• Provision of new secure modes of communication between government and citizens;
• Reduced operational cost through standardisation and economies of scale;
• Easier sharing and dissemination of information between all stakeholders;
• Facilitated deployment of enterprise-wide applications and services which enable improved and re-engineered government operations such as budgeting, financial management, human resource management, payroll and procurement; and
• Meeting pent-up demand for connectivity across government and within ministries and agencies.
Government is eager to see its agencies embrace the WAN and witness the emergence of innovative service delivery by developing e-services that will be facilitated by this state of the art network..

Which NFL team needs to upgrade its sound system?
The Atlanta Falcons are one of the NFL’s top teams when it comes to sound, and they’ve made major strides in recent years.
They’re still building the sound system, but it’s certainly not the best.
Here are some things to know about Atlanta’s sound system:• It was built in Atlanta for the team, not for the fans.
When the Falcons played in New Orleans in the 2010 Super Bowl, the stadium was only about 15 miles away from Atlanta.
That was just a few months before the city’s booming real estate market started to take off, making the Falcons’ home in New York’s East River a popular spot for events.
The Falcons were the only NFL team that had an outdoor stadium before New Orleans’ Super Bowl.
The Saints, meanwhile, had a new indoor stadium built in the early 1990s.
This time around, the Falcons and Saints had a separate outdoor stadium in New Jersey.
The Falcons’ facility had a unique sound system.
It was built for the stadium’s fans.
The sound system’s design is based on a sound board that is actually attached to a soundboard in the front of the building, where the soundboard is installed.
The audio is sent to the speakers in the sound room, and the speakers are connected to the sound board by two pairs of cables.
The speakers are the loudest and loudest of the three in the system, and their volume can go as high as 250 decibels.
This allows the system to reach a volume level that is about half of what the stadium is used for, according to the Atlanta Journal-Constitution.
This is how the sound looks:Atlanta’s sound room has a sound booth that is attached to the building.
It’s located in front of a sound deck, a room with three large speakers that can be set at any height.
There are also speakers for sound boards.
The soundboard itself is designed to have a sound that can reach 250 decibel levels.
The team uses sound boxes, which are basically sound boards that are designed to be built in a room and can be moved from room to room, making it more portable.
This makes the sound booth sound much quieter than its peers.
There’s no need to add an extra speaker when you have a traditional sound board.
The Atlanta team even has its own speakers, located on the outside of the sound deck.
The system is powered by a proprietary battery.
The battery has a special feature that allows it to recharge in a matter of seconds.
It also provides a battery backup that allows the team to take care of some of the more common power problems in a sound system that have a time limit.
This sound system is designed specifically for the Atlanta Falcons.
It can be installed in just about any place you want.
It doesn’t need to be installed next to the stadium.
There are a number of ways the team can improve its sound, including installing a new sound system in a separate location.
Atlanta is one of just four NFL teams that has an outdoor facility.
It would be nice to see more teams upgrade to an indoor facility.

Smart cities, self-driving cars, advanced home and building automation, digital healthcare, augmented reality, virtual reality. These are just a few examples of innovative applications that 5G mobile networks will make available in the near future.
5G will offer ultra-high transmission speed with low latency and will be able to provide services to a huge number smartphones and IoT devices.
It is, therefore, essential to secure the full and continuous operation of 5G networks and protect them from attacks that may lead to critical disservices or to the disclosure of personal and confidential data.
But, nowadays, there is a significant lack of adequate skills, both in private companies and public administrations. Hence the need to train a generation of technicians and managers able to efficiently support 5G cybersecurity in terms of infrastructures, applications and data.
In order to tackle these challenges, CNIT (Consorzio Nazionale Interuniversitario delle Telecomunicazioni) and Digitance have signed a MoU in Rome (Italy) on 2020.10.12, joining their effort to deliver a Continuing Education Program on 5G Cybersecurity.
The program will address both public administrations and companies aiming to invest in training technicians and managers on fundamental security issues of 5G infrastructures and applications. It will be supported by the most advanced training methodologies and with a total interchangeability between face-to-face and remote teaching. This way, it will answer not only to the needs of the present socio-health emergency, but also to the efficiency and optimization issues of all its users.
Current time schedule to training kick off is March 2021.
Finally, CNIT and Digitance intend to align, as far as possible, methodologies and contents of this initiative to what is proposed by the UN Agenda 2030, in terms of Sustainable Development.

Computer networks enable communication for every business, entertainment, and research purpose. The internet, online search, email, audio and video sharing, online commerce, live-streaming, and social networks all exist because of computer networks.
LAN (local area network): A LAN connects computers over a relatively short distance, allowing them to share data, files, and resources. For example, a LAN may connect all the computers in an office building, school, or hospital. Typically, LANs are privately owned and managed.
Computer networks connect nodes like computers, routers, and switches using cables, fiber optics, or wireless signals. These connections allow devices in a network to communicate and share information and resources.
Routers are virtual or physical devices that facilitate communications between different networks. Routers analyze information to determine the best way for data to reach its ultimate destination. Switches connect devices and manage node-to-node communication inside a network, ensuring that bundles of information traveling across the network reach their ultimate destination.
Computer network architecture defines the physical and logical framework of a computer network. It outlines how computers are organized in the network and what tasks are assigned to those computers. Network architecture components include hardware, software, transmission media (wired or wireless), network topology, and communications protocols.
As noted above, a mesh network is a topology type in which the nodes of a computer network connect to as many other nodes as possible. In this topology, nodes cooperate to efficiently route data to its destination. This topology provides greater fault tolerance because if one node fails, there are many other nodes that can transmit data. Mesh networks self-configure and self-organize, searching for the fastest, most reliable path on which to send information.

Communication protocols allow different network devices to communicate with each other. They are used in both analog and digital communications and can be used for important processes, ranging from transferring files between devices to accessing the internet.
Computer networks may be classified by many criteria, including the transmission medium used to carry signals, bandwidth, communications protocols to organize network traffic, the network size, the topology, traffic control mechanism, and organizational intent.
Computer networking may be considered a branch of computer science, computer engineering, and telecommunications, since it relies on the theoretical and practical application of the related disciplines. Computer networking was influenced by a wide array of technology developments and historical milestones.
A computer network extends interpersonal communications by electronic means with various technologies, such as email, instant messaging, online chat, voice and video telephone calls, and video conferencing. A network allows sharing of network and computing resources. Users may access and use resources provided by devices on the network, such as printing a document on a shared network printer or use of a shared storage device. A network allows sharing of files, data, and other types of information giving authorized users the ability to access information stored on other computers on the network. Distributed computing uses computing resources across a network to accomplish tasks.
A firewall is a network device or software for controlling network security and access rules. Firewalls are inserted in connections between secure internal networks and potentially insecure external networks such as the Internet. Firewalls are typically configured to reject access requests from unrecognized sources while allowing actions from recognized ones. The vital role firewalls play in network security grows in parallel with the constant increase in cyber attacks.
In a protocol stack, often constructed per the OSI model, communications functions are divided up into protocol layers, where each layer leverages the services of the layer below it until the lowest layer controls the hardware that sends information across the media. The use of protocol layering is ubiquitous across the field of computer networking. An important example of a protocol stack is HTTP (the World Wide Web protocol) running over TCP over IP (the Internet protocols) over IEEE 802.11 (the Wi-Fi protocol). This stack is used between the wireless router and the home user's personal computer when the user is surfing the web.
In packet-switched networks, routing protocols direct packet forwarding through intermediate nodes. Intermediate nodes are typically network hardware devices such as routers, bridges, gateways, firewalls, or switches. General-purpose computers can also forward packets and perform routing, though because they lack specialized hardware, may offer limited performance. The routing process directs forwarding on the basis of routing tables, which maintain a record of the routes to various network destinations. Most routing algorithms use only one network path at a time. Multipath routing techniques enable the use of multiple alternative paths.
A backbone network is part of a computer network infrastructure that provides a path for the exchange of information between different LANs or subnetworks. A backbone can tie together diverse networks within the same building, across different buildings, or over a wide area. When designing a network backbone, network performance and network congestion are critical factors to take into account. Normally, the backbone network's capacity is greater than that of the individual networks connected to it.
A wide area network (WAN) is a computer network that covers a large geographic area such as a city, country, or spans even intercontinental distances. A WAN uses a communications channel that combines many types of media such as telephone lines, cables, and airwaves. A WAN often makes use of transmission facilities provided by common carriers, such as telephone companies. WAN technologies generally function at the lower three layers of the OSI model: the physical layer, the data link layer, and the network layer. 2b1af7f3a8
