The VME family of specifications has grown significantly since its inception. VMEbus has expanded from the original family of a core VME32 parallel bus specification, a VME Subsystem bus, and a VME serial interconnect to today's broad family of complementary state-of-the art specifications.
As the serial switch fabric solutions that include Ethernet, PCI Express, RapidIO, Infiniband and other alternatives gain popularity and additional usage to form critical mass in the industry, specific purpose parallel and serial subsystem buses will start sharing market space by solving different problems within tomorrow's embedded systems. VITA is evolving to incorporate the appropriate alternatives.
VITA Technology includes several mezzanine specifications that have been optimized for use in critical embedded system environments. Low profile, small form factor mezzanine solutions of various types have been developed with several obtaining ANSI approval. IP modules, M-modules, PC*MIP, FMC, and the very popular PMC modules all work effectively in critical embedded system applications, evolving as technology and application needs change.
Several system management and support specifications have also been ratified that make the development of systems easier with more robust system management. Proposals continue to be submitted and considered for addition to the VITA Technology family to improve utilization in complex systems.
VITA is also involved in activities to enhance reliability prediction and certification standards as it relates to electronic modules. The Reliability Prediction Community is leading the efforts to improve the tools available to designers.
The specifications database has a complete listing of the many specifications along with their current status.

|ANSI/VITA 1.0-1994 (S2011)||VME64||The VME64 specification establishes a framework for 8-, 16-, 32, and 64-bit parallel-bus computer architectures that can implement single and multiprocessor systems. This bus includes the initial four basic sub-buses: (1) data transfer bus, (2) priority interrupt bus, (3) arbitration bus, and (4) utility bus. The data transfer bus supports 8-, 16-, 32-, and 64-bit data transfers in multiplexed and non multiplexed form. The transfer protocols are asynchronous with varying degrees of handshaking dependent on the speeds required. The priority interrupt subsystem provides real-time interrupt services to the system. The allocation of bus mastership is performed by the arbitration subsystem which allows the implementation of several prioritization algorithms. The utility bus provides the system with power plus power-up and power-down synchronization. The mechanical specifications of boards, backplanes, subracks, and enclosures are based on IEC 297 and IEEE 1101.1 specifications, also known as the Eurocard form factor. Additional standards exist that can be used as sub-busses to this architecture for data transfer transactions, peripheral interfaces and intra-crate communications among compatible modules.||ANSI Stabilized|
|ANSI/VITA 1.1-1997 (S2011)||VME64x Extensions||This specification is an extension of the ANSI/VITA 1-1994, VME64 specification. It defines a set of features that can be added to VME32 and VME64 boards, backplanes and subracks. These features include a 160 pin connector, a P0 connector, geographical addressing, voltages pins for 3.3V, a test and maintenance bus, and EMI, ESD, and front panel keying per IEEE 1101.10.||ANSI Stabilized|
|ANSI/VITA 1.3-1997 (S2011)||VME64x 9U x 400 mm Format||This specification is an extension of the ANSI/VITA 1-1994, VME64 specification. It defines 9U x 400 mm boards, backplanes and subracks.
The VME64x specification expands the features of VME64 mainly by using a different 160 pin connector. These and other features in the VME64x standard gained the interest of the Telecommunications Industry and the Physics Research Community. A major concern in both groups was a larger board format yet keeping as much compatibility with the existing VME standards as possible. This standard is a response to these needs.
|ANSI/VITA 1.5-2003 (R2009)||VME 2eSST||This specification is an extension of the ANSI/VITA 1-1994, VME64 and ANSI/VITA1.1-1997, VME64x specifications. It defines a transfer protocol, based upon source synchronous concepts, that permits the VMEbus to operate at rates to at least 320MB/s. As technology improves, this rate can be extended to higher levels.
The 2eSST protocol requires low skew between signals and monotonic rising and falling edges on the signals. To meet these requirements, limited length backplanes, special backplane topologies and/or enhanced transceivers are required. The specification calls for enhanced bus transceivers with controlled rise and fall times, tightly defined thresholds, low part to part skew and LVTTL levels. During the development of this standard, specific transceivers were developed to meet these requirements.
|ANSI/VITA 1.6-2000 (S2011)||Keying for Conduction-cooled VME64x||This specification is an extension of the ANSI/VITA 1.1-1997, VME64x specification. It defines an alternate keying system that can be added to VME64x boards and backplanes in a conduction cooled environment (IEEE 1101.2) where keying as defined in the VME64 Extensions standard cannot be applied.||ANSI Stabilized|
|ANSI/VITA 1.7-2003 (R2009)||Increased Connector Current Level||The P1/J1 and P2/J2 current rating limits of the 3 row DIN and 5 row DIN connector pins listed in the DIN41612, IEC 603-2 and 61076-4-113 specifications are based on full loading of the connector. In VME, VME64, and VME64 Extensions applications, the power pins represent only a small fraction of the total number of pins and are spread throughout the connector. The remaining pins are used to carry electrical signals, which add a negligible heating contribution. The net effect is that the connector heating is less, which allows a higher current carrying capacity.
Power contacts of connectors tested and certified in accordance with this standard are capable of passing 2.0 amps per contact on a selected group of pins. The standard has been verified by testing connectors from multiple vendors and it has been developed and approved by a broad cross-section of the VMEbus community.
|ANSI/VITA 3-1995 (S2011)||Board Level Live Insertion||This specification identifies methodologies through which a faulty board can be removed from a system and a replacement board can be inserted while the system continues to operate. The primary motivation for supporting Board Level Live Insertion within the VMEbus environment is to enhance the current VMEbus standard while maximizing the use of existing off-the-shelf VMEbus products.||ANSI Stabilized|
|ANSI/VITA 4.0-1995 (S2011)||IP Modules||This specification defines a versatile module, known as an "IP module." These modules provide a convenient method of implementing a wide range of I/O, control, interface, slave processor, analog and digital functions. IP modules, about the size of a traditional business card, mount parallel with a host Carrier board, which provides host processor or primary bus interfacing, as well as mechanical means for connecting the IP module's I/O to the outside world. Typical Carriers include standalone processors, DSP based carriers, as well as desktop buses and VME based boards. This specification includes mechanical, host bus electrical, and logical definition of I/O space, memory space, identification space, interrupts, DMA, and reset functions. Two physical sizes, two fixed clock rates, and multiple data width sizes to 32-bits are defined.||ANSI Stabilized|
|ANSI/VITA 4.1-1996 (S2011)||IP I/O Mapping to VME64x||With the development of the VME64x, 205 user defined I/O pin are available for rear backplane I/O. It is practical to route multiple IP's I/O through the VME64x backplanes. This standard defines the mapping of the 50 user defined I/O pins from the IP module (ANSI/VITA 4-1995 (R2002)) I/O connectors to VME64x board's rear I/O connectors in a consistent method across all VME64x boards, backplanes and rear I/O transition boards.||ANSI Stabilized|
|ANSI/VITA 5.1-1999 (S2011)||RACEway Interlink on VME||This specification provides a definition of the data link protocol and physical interface of a high performance extension to the VMEbus specification. This extension consists of high bandwidth, low latency interconnects across a VMEbus computer chassis backplane using the P2 connector. Bi-directional connectivity between boards in a VMEbus chassis is achieved through the use of a network of crossbar switches with point-to-point interconnects. RACEway Interlink is a VMEbus enhancement that can deliver up to 3.2 Gbytes/sec of scalable bandwidth over rows A, C, D and Z of the P2 connector in a standard VMEbus chassis. In addition to increased bandwidth, RACEway Interlink offers: 1) low latency, deterministic transactions, 2) concurrent point-to-point transactions for multiple simultaneous transfers, and 3) scalable bandwidth so total bandwidth increases as more slots are added. Many new applications, especially those with multiple processors and multiple real-time I/O interconnects, require these capabilities.||ANSI Stabilized|
|ANSI/VITA 6.0-1994 (S2011)||Signal Computing System Architecture (SCSA) on VME||The Signal Computing System Architecture (SCSA) specification establishes a framework for the inter- and intra-system transfer of serial media data and control information oriented toward the development of high density call and voice processing products and systems. The SCSA architecture is application specific and is embodied as a family of buses that are defined in this physical layer of the specification to reside on the VMEbus J2/P2 connector. The SCSA buses coexist with products compliant with ANSI/VITA 1-1994, VME64. SCSA at the physical level consists of two separate subbuses, a sixteen line, TDM data transfer bus called the SCbus, and a serial, peer-to-peer communication link called the SCmessage bus. The primary purpose of the SCbus is to support the exchange of real time telephonic voice, facsimile, data, video and other media streams. The purpose of the SCmessage bus is to transport interprocess control and status messages. This specification defines only the physical and data link OSI layers of the eventual four layer transport facility.
The SC data transport bus is a synchronous, byte-serial, continuously framed bus organized as 16 serial data paths each divided into 32, 64, or 128 eight bit timeslots with a frame rate of 8,000 per second in order to accommodate intra-system telephonic voice and data transfers. The message bus is an HDLC framed, 2 Mbps, CSMA/CD packet bus that is bit-synchronized with the data transport bus. This specification covers the hardware specific elements of the VME-SCSA subbus including the message bus OSI protocol layers 1 and 2. Subsequent specifications provide an interface definition for the device specific software layer that provides compatibility between compliant VME-SCSA products and available upper layer SCSA resource management application programming interface(api) and other application software.
|ANSI/VITA 6.1-1996 (S2011)||SCSA Extensions||Addition of SCSA extensions to ANSI/VITA 6.0.||ANSI Stabilized|
|ANSI/VITA 10-1995||SKYchannel Packet Bus on VME||This specification describes a high performance SKYchannel Packet Bus architecture that is fully compatible with the VMEbus standards. This standard addresses communication between VME boards using the P2 connector. This includes the physical layer for communication between the VME board and a SKYchannel Backplane through VME P2/J2, and the data link layer for communication from board to board.
This specification does not address the physical layer for running SKYchannel within a SKYchannel Backplane or group of Backplanes, which is considered an implementation detail. The specification includes specifics of the packet protocol, signals, waveforms, timing diagrams and mechanical specifications.
|ANSI/VITA 12-1997 (S2012)||M-Module||This specification defines minimum mechanical and electrical characteristics of M-Modules, a method of implementing modular circuit boards with specific functions that can be used to add functionality to other larger printed circuit boards.
For special requirements, a third row can be added to the base board connection. This is described in the mechanical specification. The use of the additional signals or extended use of existing signals (in compliance with the basic electrical specification) can be standardized to a certain extent. Therefore, certain signals and signal groups are defined in the extended electrical specification as regards their function, timing and electrical characteristics. Modules complying with these additional specifications are designated MA-Modules.
|ANSI/VITA 17.0-1998 (S2011)||Front Panel Data Port (FPDP)||This extension to the VME specification consists of a multi-drop synchronous parallel non-addressable bus connection between multiple boards in a single chassis. The connection is made to a connector on the front panel of each board by means of an eighty conductor ribbon cable. The purpose of this specification is to allow products to be designed to work with other FPDP products. The degree of interoperability may depend on the layers of functionality above the physical and data link layers. These higher layers are not part of this specification.||ANSI Stabilized|
|ANSI/VITA 17.1-2003 (R2009)||Serial Front Panel Data Port||As the name implies, it is directly related to the Front Panel Data Port (FPDP) specification, deriving its serial protocol from the defined protocol and control signals of FPDP. This Serial FPDP specification supports three link speeds: 1.0625 Gbaud, 2.125 Gbaud, and 2.5 Gbaud. These three link speeds can support data transfer rates in excess of 105 MBps, 210 MBps, and 247 MBps respectively. Included in this definition are the data frame structure, the link layer protocol, and the physical media requirements.
The purpose of this specification is to allow products to be designed to work with other Serial FPDP products. The degree of interoperability will depend on the specific options implemented. Although all options are supported by this standard, not all products are required to support all options.
|VITA 17.2||Serial Front Panel Data Port (SFPDP) Channel Bonded Protocol||The main objective of VITA 17.2 is to increase the bandwidth of the link. This can be done by both increasing the speed of the link, and by providing the ability to channel bonding several lanes together.
The VITA 17.2 protocol is designed to provide functional compatibility with both VITA 17 and VITA 17.1 protocols, while providing increased bandwidth. In addition, the VITA 17.2 protocol is designed to provide a minimum footprint, and to maximize the use of dedicated hardware that is found in current FPGAs.

|ANSI/VITA 20-2001 (R2011)||Conduction Cooled PMC||This specification defines the methodology and implementation details to allow the creation of conduction cooled PMC modules to ensure electrical and physical compatibility with various host card modules onto which conduction cooled PMCs are mounted.
The goal of this specification is to allow the intermixing of different vendors air and conduction cooled PMC modules onto air and/or conduction cooled host card modules to the maximum extent possible.

|ANSI/VITA 30.0-2000 (S2011)||2mm Connector Practice for Eurocard Systems||This document defines an equipment practice based on a combination of 2 mm connectors, per IEC 61076-4-101, and subracks, racks and printed boards based on the Euroboard form factors.
In the late 1980's, the VME specification expanded for 64 bit data and address capability, which also affected the specified connectors used at the plug-in module interface. The designers utilized IEC 61076-4-101 2 mm based connectors to increase connector pin counts and to facilitate the adoption of certain architectural features and capabilities. Physical features required to incorporate these connectors into the IEEE 1101.1 and IEC 60603-2 based architecture were detailed in the individual specifications. This document provides a means to specify this information without including extensive details in the systems specifications. The combination of Euroboard form factors and 2 mm connectors has been utilized in other system architectures and is anticipated to be included in future systems. This specification defines a variety of configurations that combine Euroboards and 2 mm connectors in a manner that facilitates references to such architecture in such current and future applications.
|ANSI/VITA 30.1-2002||2mm Connector Practice for Conduction Cooled Euroboards||This specification is intended to be a companion specification to other standards as referenced. Other uses for this specification are in no way prohibited. The aim is to ensure mechanical interchangeability of conduction-cooled circuit card assemblies in a format suitable for military and rugged applications and to ensure their compatibility with both conduction cooled chassis and commercial, air-cooled, single height (3U) and double-height (6U) x 160mm, Euroboard chassis.||ANSI Ratified|
|VITA 30.2-2001 (IEC)||Power Connector Equipment Practice||This document describes various separable connectors that can be used to conduct electrical current between two printed boards. Typical applications include power supplies or other power management devices. It has been developed to aid in the design of equipment where such connectors are typically found. The information included consists of interface and profile dimensions, printed board layout dimensions, suggested or actual signal and power pin assignments as well as information regarding standards that may exist for the connectors. No consideration is given to current carrying capacities of the connector systems nor to the optimization or validity of any pin assignment schemes, which may be included. Similarly, if connector locations are given relative to common industry board practices, they are not to be assumed to be the sole possible location of such connectors. Power connectors are defined, for the purpose of this standard, as separable connectors that are designed to provide current to devices at levels consistent with the overall operating power of the device. As such, they must have at least one (1) contact capable of carrying five (5) amps or more of electrical current.||Industry Technical Agreement|
|ANSI/VITA 31.1-2003 (R2009)||Gigabit Ethernet on VME64x Backplanes||This specification leverages the PICMG 2.16 packet Switched backplane specification that adds a switched network based on Gigabit Ethernet to CompactPCI backplanes. The PICMG 2.16 CompactPCI P3 connector has two Gigabit Ethernet ports for improved performance and redundancy. The CompactPCI P3 connector and the VME64x P0 connector are identical IEC 61076-4-101 2 mm based connectors and have the same placement on the backplane. This standard adopts the PICMG 2.16 P3 connector pin assignment for use on VME64x boards. This standard also adopts the definition of the fabric card described in PICMG 2.16. PICMG 2.16 compliant systems and VITA 31.1 systems can use the same switched fabric boards.||ANSI Ratified|
|ANSI/VITA 32-2003 (R2009)||Processor PMC||The complete physical (mechanical) and the environmental layers are retained as specified in the IEEE 1386 CMC ("Common Mezzanine Card") standard except as noted in this document. If the information in this document contradicts IEEE 1386 or IEEE 1386.1, this document takes precedence.
Processor PMC cards are used where modular attachment of a processor is desired. These processor PMC cards may be used in conjunction with PMC I/O cards, traditional PCI cards, or with directly attached PCI components. As such, Processor PMCs increase the modularity of a computer system and thus complement, rather than compete with, the existing family of PMC cards.
Processor PMC cards are expected to electrically operate with existing carrier boards (or motherboards); that is, while the carrier may be redesigned to take advantage of the enhanced functions that are offered by this standard, such a redesign should not be a requirement to insure proper operation. Indeed, Processor PMCs shall be specifically enabled to operate as master/host CPUs; otherwise, such cards revert to traditional PMC modes, operating as intelligent slave/target processor boards.when that support is required within PMC and Processor PMC designs.
|ANSI/VITA 35-2000 (R2011)||PMC-P4 Pin Out Mapping to VME P0 and VME64x P2||This specification provides pin mapping assignments between a PCI mezzanine Card (PMC) module's user IO connector (P4) and the VME host's user IO connector. Four mappings are provided.
Other standards such as Compact PCI (CPCI) which supports a PMC and a VME-P0 style connector on the host could also use this standard.
|ANSI/VITA 38-2003 (R2008)||Intelligent Platform Management Interface (IPMI) with VME||This specification is based on the PICMG 2.9 System Management specification and describes the additional requirements for implementing Intelligent Platform Management Interface (IPMI) in a VME system. IPMI describes a hardware independent interface between chassis sensors and the operating system. IPMI is particularly useful for managing servers and High Availability systems.||ANSI Ratified|

This document describes a service indicator standard that seeks to be as compatible as possible with existing indicator standards and their extensions across different product markets. This standard addresses the meaning and application of specific colors to service indicators. This standard also defines and assigns meanings to specific approved behaviors or states for each color. It specifies where indicators must be placed and in what order, and it specifies luminance levels and viewing angles.
|ANSI/VITA 41.0-2006 (R2011)||VXS: VMEbus Switched Serial Base Specification||The VME Switched Serial (VXS) specification comprises this base standard defining physical features of VXS components, coupled with a set of protocol layer standards to define the specific serial interconnect used in a system implementation.
The VXS base specification defines physical features that enable high-speed communication in a VME compatible system. These features include: addition of a high speed connector to the VME64x board in the P0/J0 position, a 6U by 160mm by 6HP Eurocard format board with many high speed connectors which may act as a switch, and the backplane/chassis infrastructure needed to support these features. In addition to defining a high -speed connector in the P0/J0 area, VXS also defines alignment and keying features which may be used to protect this and future alternate connectors.
The ratio of one high-speed connector per payload board to many on the switch card lends itself to a star topology where each payload card is connected to a central switch. For higher reliability and/or load balancing, two switch cards may be used in a dual star configuration. Interswitch links may be included for reliability and load balancing reasons as well. Although this topology is not required it is a natural fit for the system features.

In telecommunications, 5G is the fifth generation technology standard for cellular networks, which cellular phone companies began deploying worldwide in 2019, the planned successor to the 4G networks which provide connectivity to most current cellphones.Like its predecessors, 5G networks are cellular networks, in which the service area is divided into small geographical areas called cells. All 5G wireless devices in a cell are connected to the Internet and telephone network by radio waves through a local antenna in the cell. The main advantage of the new networks is that they will have greater bandwidth, giving higher download speeds,eventually up to 10 gigabits per second (Gbit/s). Due to the increased bandwidth, it is expected that the new networks will not just serve cellphones like existing cellular networks, but also be used as general internet service providers for laptops and desktop computers, competing with existing ISPs such as cable internet, and also will make possible new applications in internet of things (IoT) and machine to machine areas. Current 4G cellphones will not be able to use the new networks, which will require new 5G enabled wireless devices.
The increased speed is achieved partly by using higher-frequency radio waves than current cellular networks. However, higher-frequency radio waves have a shorter range than the frequencies used by previous cell phone towers, requiring smaller cells. So to ensure wide service, 5G networks operate on up to three frequency bands, low, medium, and high.A 5G network will be composed of networks of up to 3 different types of cells, each requiring different antennas, each type giving a different tradeoff of download speed vs. distance and service area. 5G cellphones and wireless devices will connect to the network through the highest speed antenna within range at their location.

The Access Layer
In accordance with its name, the access layer is where the end devices connect to the network—where they gain access to the company network. The Layer 3 devices (such as routers) that guard the entry and exit to this layer are responsible for ensuring that all local server traffic does not leak out to the wider network. QoS classification is performed here along with other technologies that define the traffic that is to traverse the network. Service Advertisement Protocol (SAP) filters for NetWare and AppleTalk’s GetZoneLists are implemented here, in reference to the design consideration of client/server connectivity.
The Distribution Layer
The distribution layer provides connectivity between several parts of the access layer. The distribution layer is responsible for determining access across the campus backbone by filtering out unnecessary resource updates and by selectively granting specific access to users and departments. Access lists are used not just as traffic filters, but as the first level of rudimentary security. Access to the Internet is implemented here, requiring a more sophisticated security or firewall system.
The Core Layer
The responsibility of the core layer is to connect the entire enterprise by interconnecting distribution layer devices. At the pinnacle of the network, reliability is of the utmost importance. A break in the network at this level would result in the incapability of large sections of the organization to communicate. To ensure continuous connectivity, the core layer should be designed to be highly redundant, and, as much as possible, all latency should be removed. Because latency is created when decisions are required, decisions relating to complex routing decisions, such as filters, should not be implemented at this layer.
They should be implemented at the access or distribution layers, leaving the core layer with the simple duty of relaying the data as fast as possible to all areas of the network. In some implementations, QoS is implemented at this layer to ensure a higher priority to certain packets to prevent them from being lost during high congestion periods.

This project rfid based voting project is way of authenticating voters and allowing only the authorized users to vote the whole system includes rfid scanner to scan the voter id cards, 8051 microcontroller interfaced to lcd screen which will be used to display output.
Touch-screen voting machines offer many advantages that make them far superior to optical scan and other paper-based voting machines supporters of the touch-screen systems say they are superior because they offer instant translations for voters whose primary language is not english and because the disabled can use them easily and without. Technologies along with the electronic voting machine to further improve the election process and to avoid rigging we have developed a system which gives access to the evm through passive rfid and gsm module. We all are quite familiar with voting machines, even we have covered few other electronic voting machine projects previously using rfid and avr microcontroller in this project, we have used the arduino controller to create an electronic voting machine.

Many secure systems, such as contactless credit cards and secure entrance systems, are built with contactless smartcard rfid technologies in many cases thes. Electronic voting machine has now replaced the traditional mechanism of voting due to several advantages like security, automatic counting etc this kit presents a way to develop an electronic voting machine which displays the count of votes on a 16x2 lcd interface.


The broadband sector has come into the forefront of public discourse with millions of Americans struggling to stay online amidst the pandemic. In many communities, local governments have turned to creating their own solutions where private competition has not met the needs of the populace. We help municipalites and counties with Broadband projects. We help conduct the feasibility study, navigate the grant application process, facilitate the project management and the actual deployment of the broadband project.
How does a provider decide where to build? It’s all about return on investment (how quickly can the company get its cash investment back in order to reinvest in additional projects), and ability to grow the company.
Let’s look at a simple example making the following assumptions:
Access to Health Care: Telemedicine has made advances that allow for the digital transfer of information that once required traditional telephone technology. Today, high-speed fiber connections allow health care professionals to evaluate, diagnose, and treat patients in remote locations using telecommunications technology. Fiber optic Internet provides seamless video connections, so patients in remote locations can access medical experts quickly and efficiently without having to travel.
Aside from the obvious access to information for studying, children and their parents can always be engaged in the educational process through educational web portals. These portals provide an interface to communicate with teachers and administrators, real-time access to assignments and grades, and numerous educational resources.
When internet is treated as a public utility like gas, water or electricity, it can help residents find jobs, do homework at home more easily and connect easier to new technology like tele-health.

SELECTING THE RIGHT TELECOMMUNICATIONS INDUSTRY MERGERS.
Mergers and acquisition in business generally imply the coming together of the business entities combining to form a company or a bigger business. When it comes to talking about telecommunication industry mergers, here two industries of somehow equal sizes join to form a big telecommunication company. For any investor to get back their investment regarding profit in the telecommunication business, the investor is required to place a large investment towards the same.
A little research needs to be done when one thinks of venturing into this business, and the best of it all is the maybe thinking of merging with an already established industry so that the company can pick up. The wide variety of different industry specification and companies provides a good platform for individuals to invest in the telecommunications industry business. Telecommunications include radio, television, telephone, mobile or cell phone and the broadband companies among others.
Orlando telephone company is an example of a telecommunications company that entrepreneurs can choose to merge with when it comes to joining with another company. Portfolios are increasingly growing in sizes, and this is because of the merging of larger companies to form one big one so that high profit can be realized at the end because of the upgrading of the companies on a daily basis. There are so many business platforms for investing your money, but when you think in the line of safety of your money, telecommunication investment is the best option ever because of its long stability that has been experienced by other investors.
Like any other investment opportunities, the investor has to closely examine the risks and advantages associated with the telecommunication investment, after which one is the best place to select the kind of telecommunication industry mergers to collaborate with. This in general helps one to make an investment they are confident in and are sure that it will eventually be successful.
Changing the support in technology and the services of consultancy firms in varied regions in the world countries has proven a vital source of controlling the costs in the world’s technological companies, telecommunication industries being among them. In the areas where telecommunication capabilities have been well distributed, the talents are well natured, and growth is evident because all the workforce is focused on these resources for the development of the telecommunication industries.
Making the right choice between the vast majority of the investment platforms available is a bit hard and confusing, when one is especially navigating through the business market in the quest of searching for the best investment. Increasing shareholder’s value above the combination of two companies is the key reason why most of the telecommunications industries are merging because the initial aim any investment is profitability. The future of the telecommunication industry predicts the ongoing success.


Well, it seems like some wild conspiracy theories are being spread around concerning the newest generation of wireless technology. I suppose, you guys had a lot of time to think while stuck at home. And apparently, even more, time to read and watch lots of YouTube videos about the potential danger that the towers may or may not cause. It makes sense while the world is rapidly changing it would be helpful to have a scapegoat of some kind for plenty of negative things. But is there any substance behind these claims? Hello, friends and philosophers now we will discuss: Why people are concerned about 5G and should we be afraid of 5G networks?
there are plenty of different categories of worry out there and I am trying to address as many as possible. I don’t claim to be an expert on any of these topics. I would encourage you all to do your own research as well to deepen your understanding of the subject.
Let’s get going and know what 5G is exactly? 5G doesn’t stand for anything other than the fifth generation. This is the fifth update to the mobile network that has been powering phones and similar devices for decades.
So, 1G was analog audio, 2G was digital audio, and 3G was the introduction of wireless data. 4G brought us mobile broadband and 5G is the latest iteration as the new global wireless standard. It’s meant to connect all sorts of new things and improve upon the connectivity between the Internets of things to ensure that it all works the way people are hoping it.
Does 5G introduce lower latency?
More reliability, higher bandwidth, and increased efficiency, all require new hardware. Which has led to the installation of new towers all over the place. It’s possible that you first heard of this happening because people were attacking these towers by enabling new and faster connections between the Internets of things. 5G developers hope that it’ll be helpful for running things like self-driving cars and smart city technology. It’s very fast which allows things on the network to communicate in almost real-time.
To get this fast 5G communicates on a higher frequency and requires more towers to be installed. This can be expensive but also allows for more users to more reliably take advantage of the network. So far it’s begun a slow rollout seeing deployment in a few countries most notably South Korea, the US, and China. However, as I mentioned earlier it all needs new infrastructure to run so it’s taking a while to install new towers and update older ones with new equipment. It will be a while before we see 5G operating at full capacity but slowly more people are gaining access to it.
As its deployment increases, concern among people will likely rise. This isn’t a new phenomenon on health, and safety concerns have always increased around the time of new wireless generations.
There are reasons and legitimate studies that raised concerns about 5G networks and their impact on the health of humans and other organisms. However, none show conclusive evidence that there are negative effects. Again it’s still early in the text lifespan and it’s probably a good idea for people to do additional high-quality research and get substantial answers. We don’t have the answers for everything yet, but it’s good to know the questions.
Link with Covid19
First I want to address is one that’s been getting plenty of news coverage over the past little while the connection between 5G networks and covid19. I will be as clear as possible there is no scientific evidence of a link between 5G & coronavirus. So many people have been making baseless claims like that 5G networks outright caused Covid19 and related symptoms.
Do you know how the virus works? The only way for you to contract the virus is to come in contact with another organism with that virus. (Either it is through direct touch or swallowing or inhaling something with the virus). You cannot get a virus from radio waves.
Others have been saying that 5G networks are weakening immune systems. And making it more likely that a person gets infected. This is also untrue. The radiofrequency or RF waves are given off by cell phones do not have enough energy to damage DNA or affect the body. And other such ways these arguments are being lent credence by a correlation between two factors:
5G networks and infrastructure began to become more widely used and built around the same time that coronavirus originally broke out. People started to notice that place is being hit hardest by Covid 19 were also places that had recently had 5G technology installed. This is a common logical fallacy and is often used to correlate unrelated things. Correlation does not equal causation. The virus breaking out around the same time as 5G becoming more prevalent was just unfortunate timing.
The idea that large metropolitan areas with 5G were more vulnerable to Covid19 has more to do with the fact that densely populated zones basically virus breeding grounds. At this point at least 184 countries have reported cases of the virus. While only a select few have any 5G infrastructure installed upgrades.
5G Radio waves cause Cancer?
Wireless technology has been falsely linked to diseases before and this isn’t likely the last time we’ll see it happen. Many of the conspiracy theories linking 5G to Covid come from groups that have made arguments like this in the past like claiming wireless airwaves caused cancer. Theories drawing lines between cancer and wireless have been around for a while so it would make sense that a more powerful network be put under similar scrutiny.
However, the International Commission for non-ionizing radiation protection has declared 5G completely safe. This, of course, is as long as the new guidelines they drove or followed. But that should be the case 5G has been in development for a long time now. And took this commission seven years to complete their guidelines. In addition to these tests from the UK communications, the regulator found that EMF emissions from 5G are at a fraction of the highest safe level. In fact, cell phones have energy levels lower than microwaves and TVs.
5G is actually worse at penetrating objects than 4G which is why smaller cell sites are being built close together. Again 5G is still early in its lifespan and more extensive studies do need to be done. As of right now, there is nothing substantial indicating that 5G is physically harmful to humans.
There are concerns beyond the physical. Some claims are being made that 5G may interrupt other wireless technology. A major concern right now involves the accuracy of the weather report. 5G antennas transmit signals near the frequency that NASA and NOAA used together for water vapor data. This could reduce the accuracy of weather reporting and long-term forecasting.
The last big 5G concern has to do with security. While 5G should be more secure than 4G networks there are some backdoor measures put in place by manufacturers and suppliers that should be exploited. Officials in the US are trying to make a case for them and their allies to ban Chinese telecom company, Kwame, from supplying infrastructure for 5G networks. Going forward security advisors say that supply chain concerns have to be taken seriously.
US officials claimed that China, especially Huawei could have access to these. If they’re behind the manufacturing of parts and devices. China refuses these claims saying that only certified personnel from network operators will be able to access such information.
So keep your eyes peeled for new developments. Now that we’ve taken a look at a bunch of different areas of interest. Let’s return to our original question should we be afraid of 5G networks? and the answer is it depends in terms of physical safety. 5G should be no more dangerous than any other wireless technology.
But the introduction of new tech opens up the possibility of it being exploited or avertedly affecting other technologies. What we should be afraid of is misinformation. So do your research and look for reputable sources for information. Just because you heard it online doesn’t mean it’s true and I know how that sounds coming from me.
So what’d you think? What concerns you most about 5G? How do you think conspiracy theories spread?


Time Warner Cable plans to start charging its broadband customers a monthly fee to use company-issued modems.
The $3.95-a-month fee will start with the next billing cycle, spokesman Dave Borchardt said.
"We are continually investing in our network to ensure the fastest, most reliable Internet service for our customers, and this new fee will help support these ongoing infrastructure improvements and service enhancements," he said in an emailed statement.
Borchardt said such a fee is standard across the industry, and Time Warner is among the last providers to start charging it.
He also said Time Warner's fee is lower than most. According to published reports, both Comcast and Cox Communications charge modem-rental fees. Comcast's fee is $7 a month.
Not all customers will be charged the fee. Signature Home package customers, for example, are exempt.
Customers can avoid the fee by buying their own cable modems, as long as they are compatible with Time Warner Internet service.
Also this Week, Time Warner announced a new Internet pricing program called Essentials Internet.
The plan is aimed at light users who have the Lite, Basic or Standard Internet service. Those users can save $5 a month if they keep their monthly data transmission usage to 5 gigabytes or less. Overages cost $1 per gigabyte, up to a maximum of $25 per month.
Time Warner Cable customers can monitor their Internet usage by accessing their MyServices account at www.timewarnercable.com/myservices.


Built with the company's sensAI solution stack and running on low-power Lattice Nexus FPGAs, the new solutions are designed to help OEMs develop smart, always-on devices with low power, hardware-accelerated AI capabilities that are field upgradeable to support future AI algorithms. The solutions are offered as a platform for developing computer vision and sensor fusion applications that improve engagement, privacy, and collaboration for users.
For example, a client device can leverage image data from its camera to determine if someone is standing too close behind the user and blur the screen for privacy or lengthen battery life by dimming the device’s display when it “sees” the user’s attention is focused elsewhere.
“AI applications based on vision, sound, and other sensors will revolutionize the Client Computing experience,” says Matt Dobrodziej, Vice President of Segment Marketing and Business Development at Lattice. “Our sensAI solution stack supports a roadmap of Edge AI applications that make Client devices contextually aware of how, when, and where they’re being used, and our Nexus FPGAs deliver that functionality with class-leading low power consumption.”
Compute devices using an AI application developed with the sensAI solution stack and running on a Lattice FPGA have a 28 percent longer battery life in comparison to devices powering AI applications with their CPUs, says the company. The sensAI solution stack also supports in field software updates to keep pace with evolving AI algorithms and provides OEMs the flexibility to choose from different sensor and SoC technologies for their devices.
Enhancements and new features of the latest version (v4.1) of sensAI include:
- Client Compute AI experience reference designs –
- User presence detection to automatically power on/off Client devices as a user approaches or departs.
- Attention tracking to lower a device’s screen brightness to conserve battery life when the user isn’t looking at the screen.
- Face framing to improve the video experience in video conferencing applications.
- Onlooker detection to realize when someone is standing

A village community on the Lizard peninsula now has access to lightning fast broadband after a local company stepped in after hearing their plea.
Goonhilly-based wireless internet company, Wildanet, has transformed the internet experience for 14 residents of Gunwalloe with more awaiting installation.
The company claim that internet speeds previously averaged less than 1.5Mbps, yet now say residents are enjoying minimum guaranteed speeds of 20Mbps.
Aaron Coward of Wildanet said: “Because our wireless internet uses radio waves through the air, it can be deployed to a village or community far more quickly than fibre optic or copper networks. We’re covering major areas of the Lizard currently and building our network but we have the flexibility of being able to target specific communities if there is a requirement to do so.”

New train technology is being demonstrated to stakeholders that could make the UK rail network safer for track maintenance workers, train crews and passengers.
Thales is working with Network Rail and the West Somerset Railway (WSR) to run a live demonstration of its Train Protection and Warning System - Continuous Supervision (TPWS-CS). An audience representing Network Rail, RAIB, ORR, supply chain, train operating companies and rolling stock owners will observe the digital, in-cab system put through its paces in real world scenarios on the 7th of April.
TPWS-CS builds on radio-based limited supervision (RBLS) system, which is currently being defined by Network Rail and industry. The new system continuously updates a train’s position and warns the driver when approaching a stretch of track closed for maintenance or under speed restrictions, applying an emergency brake if necessary. The system enables the Person in Charge of Possession to apply specific permitted movements to trains within the possession, which will be automatically supervised by the TPWS-CS to warn the driver or apply the brake when necessary. The driver can receive updates in their cab constantly, without the need for trackside infrastructure.
Alex Stockill, Product Line Manager at Thales, said: “This is a proof-of-concept demonstration, to show that this is something that exists, not an unrealistic idea. When we tell engineers what we plan to do, their reaction is that it’s too good to be true but this demo will show that the technology does exist and it works.”
He added: “We want to come out of the demonstration with the confidence of Network Rail and other potential customers. We think this system, if deployed across the UK, can make a big difference.”
The system consists of three core elements: continuous positioning sensors, including radar, a Global Navigation Satellite System (GNSS) and inertial measurement unit (IMU); an interface for communicating with the driver; and access to the emergency braking system through the existing Train Protection & Warning System.
TPWS-CS initially warns the driver if the train is approaching a track possession, an area of track taken over by a maintenance crew with restricted access or speed limit. If the train is in danger of breeching its movement authority, the system automatically applies a brake.
TPWS-CS gives controllers the ability to set movement rules around a possession, either a 0mph rule at the boundary or allowing specified trains, for example an engineering train, to enter to a certain extent and at a fixed maximum speed. This enables controlled moves of engineering trains within worksites.
The equipment will be fitted in a day to a classic diesel cab owned by West Somerset Railway (WSR), a heritage railway company, which also manages the track being used for the demonstration. Display boards on the carriages will show guests the train’s position and speed and repeat the driver’s-eye view of the cab interface.
“It’s been really good working with WSR,” said Alex. “They’ve also given us access to their track so we could carry out testing in safe conditions.
“It’s taken very little time to arrange because they are in total control of their own track, so we’ve been able to react quickly and collaboratively with them.”
The first part of the demonstration will be a series of runs at various speeds under differing restrictions and movement authorities, testing the system’s response and how the train behaves as it approaches a possession applied to the track. The second half will be a presentation of other applications possible for the system.
Innovation and collaboration
Thales has also shown that the TPWS-CS system can be fitted and integrated quickly and cheaply into a cab. The system has been installed as part of Thales’s Robust Train Positioning System on an in-service GWR Class 150 cab, which is acting as a rolling laboratory to gather data.
“These demonstrations have been down to strong collaboration between all of the stakeholders,” said Alex. “To continue innovating for the future, we have to continue working collaboratively and quickly on projects like this, which we’ve been able to set up and demonstrate inside of six months.
