Acoustic telephone ad, The Consolidated Telephone Co. Innocenzo Manzetti first mooted the Mobil ip essay of a "speaking telegraph" or telephone. Use of the "speaking telegraph" and "sound telegraph" monikers would eventually be replaced by the newer, distinct name, "telephone".
Charles Bourseul published an article in the magazine L'Illustration Paris: Reis also used his telephone to transmit the phrase "Das Pferd frisst keinen Gurkensalat" "The horse does not eat cucumber salad". Manzetti illustrated his method for transmitting spoken words on the telegraph wire intend to apply said invention in England on several private telegraph lines".
However telephones would not be demonstrated there untilwith a set of telephones from Bell. Antonio Meucci files patent caveat No.
Patent Office titled "Sound Telegraph", describing communication of voice between two people by wire. A 'patent caveat' was not an invention patent award, but only an unverified notice filed by an individual that he or she intends to file a regular patent application in the future.
Meucci, after having renewed the caveat for two years does not renew it again, and the caveat lapses. Patent"Transmitters and Receivers for Electric Telegraphs" is granted. This uses multiple vibrating steel reeds in make-break circuits. Elisha Gray invents a liquid transmitter for use with a telephone but does not build one.
Gray files a patent caveat for transmitting the human voice through a telegraphic circuit. Alexander Graham Bell applies for the patent "Improvements in Telegraphy", for electromagnetic telephones using what is now called amplitude modulation oscillating current and voltage but which he referred to as "undulating current".
Gray is notified by the U.
Patent Office of an interference between his caveat and Bell's patent application. Gray decides to abandon his caveat. The first successful telephone transmission of clear speech using a liquid transmitter when Bell spoke into his device, "Mr.

CHAPTER 25 Mobile IP Protocols CHRISTOS DOULIGERIS and THANOS VASILAKOS Institute of Computer Science, FORTH, Heraklion, Crete, Greece INTRODUCTION IP Version 4, which is the current, most implemented version of . A mobile phone, known as a cell phone in North America, is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area.
The radio frequency link establishes a connection to the switching systems of a mobile phone operator. Unless the IP telephone's components are backed up with an uninterruptible power supply or other emergency power source, the phone ceases to function during a power outage as can occur during an emergency or disaster when the phone is most needed.


In this article, I will not mention all the existing applications that help in setting up and checking synchronization. I will only cover those that I actively use myself and consider as convenient and functional as possible. This list of applications will allow you to identify and analyze any protocol and technology that we have gone over earlier or will address in future articles.
LTC-MIDI reader/converterOperating system: MAC OS, Windows
Interface/Protocols: LTC, MTC
This is a fairly convenient program that allows you to receive LTC and MTC timecode via a sound or MIDI card, displays it visually on the screen, and also, if necessary, sends it to another MIDI or LTC output. In addition, the program can convert these protocols between themselves. This is a paid program, but there is also a demo version that can work for 5 minutes.
PC TimecodeOperating system: Windows
This is a free program that allows you to display the received LTC time on screen. This app only has the most basic, necessary settings. Its main purpose is displaying on screen the received linear timecode
Clockit Timecode AppOperating system: iOS
This is the simplest program, which is similar in functionality to the previous application, but the difference is that this application only works on the iOS system. If necessary, with a required adapter, you can connect a linear signal to the smartphone and see the current time. This program is free.
MIDI Timecode Operating system: iOS
This program allows you to display the current time of the received timecode on a phone screen. This program can receive MIDI timecode on a smartphone or tablet via USB, as well as through RTP-MIDI and BLE-MIDI. This app is also free.
MIDI Timecode X
Operating system: MAC OS
Interface/Protocols: MTCThis is an analogue of the previous application, but it only works with the MAC OS. This application also works with USB devices, RTP-MIDI and BLE-MIDI. The application is free.
MIOS StudioOperating system: MAC OS, Windows
Interface/Protocols: MIDI, OSC
This program has different tools for analyzing data from the MIDI and OSC interfaces. This program has a convenient incoming and outgoing monitor, which allows you to see data packets directly. This program also allows you to test interfaces by generating test data. In my toolbox, it is the main app for analyzing OSC. Another nice feature is that this program is also free.
Touch OSCOperating system: iOS, Android
Interface/Protocols: OSC, MIDI
This is one of the most popular applications for creating touch control interfaces for mobile devices. The main protocol for which this program was developed is Open Sound Control, but if necessary, you can use MIDI. The principle of the program is very simple. You download the interface layer from the manufacturer’s website with the associated addresses of the controls (almost all sound and light consoles have ready-made layers), or through the editor, you can create your own layer. Next, you download this layer to your phone and you have a ready-made management interface. The program is paid.
MIDI OX Operating system: Windows
This program allows you to analyze MIDI data and, also in test mode, generate any protocol based on MIDI, including MTC and MIDI Time Clock. The program is free.
LOOP be Operating system: Windows
This app allow you to send MIDI messages between different apps through the same system. One channel version of the application is free, but to use more virtual MIDI channels, you must purchase a license.
IAC Driver Operating system: MAC OS
This is a preinstalled Apple driver. The purpose of this app is to create a virtual MIDI loop in the system. It can be activated and configured in the MIDI Studio window, where other MIDI equipment also exists.
IP MIDI Operating system: MAC OS, Windows
This program is very similar to RTP-MIDI technology. It also allows you to transmit MIDI messages over an Ethernet network. This software is produced by a private company that uses its own methods and algorithms for transmitting MIDI data packets over a network. Also, their own protocol that this program uses is not standardized by any of the MIDI associations. For such a protocol to be understood by mobile devices, an IP MIDI driver must already be integrated in applications. One channel version of this application is free. To work with the full version, you must purchase a license.
my MIDI RemotesOperating system: iOS
This is a group of smartphone applications that allow you to work with different MIDI protocols. Through various control protocols, visual control interfaces and timecode displays are implemented. Some applications also support IP MIDI. Some applications are free, some are paid.
MIDI mittrOperating system: iOS
This is a management program that allows you to configure routings between MIDI ports. It also independently allows you to connect to RTP-MIDI and BLE-MIDI by creating virtual MIDI ports, to provide a MIDI signal to devices that do not support these protocols.
Dyslexia Software LTDOperating system: iOS
This is a software developer for working with various MIDI protocols, both for control and settings. This manufacturer also has a wide range of applications, some of which are free. The application for displaying the time code, MIDI Timecode, which I mentioned above, is from this developer.
Touch DAWOperating system: Android
This is a fairly universal program that already has pre-installed control layers, similar to Touch OSC, except all control is carried out through MIDI notes. The program also supports RTP-MIDI protocols and can configure routing between ports. Through Google Play, you can also find many applications that emulate the operation of different MIDI keyboards, which basically can transmit only MIDI notes.
WiresharkOperating system: MAC OS, Windows
This is an indispensable program that allows you to track data packets on the local network. This program can show you all necessary information: what address the data packet came from, what data transfer protocol the packet uses, which port of departure and port of destination, and much more. This program is very useful when you work with synchronization protocols that are based on Ethernet technology. Moreover, this program allows you to display data that is sent and received by other clients and servers among themselves. And the best part is that this program is completely free.
After reading this, you may ask: “Why are there so many applications for iOS and such little professional software for Android systems?” The answer is simple: the smartphone itself. Creating an application for iOS, the programmer is confident that the application will work equally well on all mobile devices. Apple has taken care of software compatibility for all devices, and Apple is actively developing and supporting iOS and MAC OS application development tools and ideology. A good example of this is the Apple Worldwide Developers Conference (WWDC) - a global conference for developers on the Apple platform.
Android is a universal operating system that runs on mobile devices from different manufacturers. A programmer creating an Android application can never be sure that it will work equally on all devices. This especially applies to working with equipment. Since all synchronization protocols are based on physical interfaces, they are very dependent on which device and which protocol is trying to access the physical interface. As is often the case, such applications have a large number of errors on different devices. And in synchronization, reliability is an important element.
Since this problem was initially solved by Apple's equipment ideology, the professional software developers chose the most optimal way to create applications.
That is why you see most professional software available only on MAC OS or on iOS.


There will list some difference between mobile phone flash and camera built-in flash.
1) Most camera flashes use Xenon flashes and most of mobile phone use LED flashes.
2) The Instantaneous power of Xenon flashes are many times more than mobile phone flashes. Take example, if you watch the Xenon flash directly, it may make you blind. But the light of mobile phone flash is soft and sometimes it can used as flashlight.
3) The power consumption is different. LED flash can keep lighting for a long time but Xenon flash needs to wait a moment to uses again after you use it.
4) The light of mobile phone flash is soft, and it can help a lot in optimizing portrait. Xenon flash’s object is to get more exposure, and the light is harder than mobile phoneflash’s. Therefore, the external flash needs to be used with diffuser, reflector for a better photographic results.

Aerial television has not become obsolete just yet. There are still several property owners in North London who have aerial installations and televisions. This may seem strange considering how much of the population has converted to satellite television. But there are some great advantages to using aerial television instead of satellite television. Once you learn about these advantages, perhaps you’ll consider an aerial installation in North London instead of a satellite installation.
Aerial television uses an antenna instead of a dish. If you only care about receiving local television service, then you don’t need to pay any monthly fee like you would with satellite or cable. Alternatively, if you have cable or satellite, you can cancel the local television channels off your service plan and save some money on your monthly bill by using aerial technology to get them for free. Most people don’t even realize that local broadcasting stations air their programs for free as a public service. You just need an antenna to pick them up.
Cable and satellite television are always going to offer you more channels than aerial television. However, aerial television may give you access to subchannels which aren’t available on cable or satellite. This may include public television channels in your local area which your cable or satellite provider has chosen not to include in their services. You may find some interesting sports, news, and weather channels that you’ve never heard of before.
Perhaps one of the biggest advantages of aerial television is the reception of the signal. When there is bad weather outside, a satellite dish can lose the signal very easily because of the clouds in the sky. This doesn’t happen with antennas because they don’t reach for signals in the sky. Instead, they pick up signals for bigger antennas on the ground in the local area. That means you’ll likely get better reception with an aerial television when there’s a storm outside.
Overall, you’ll probably end up wanting both aerial and satellite/cable installations. A lot of companies that offer aerial installation in North London also offer other similar services too, such as CCTV in North London or door entry installation in North London. FixSat is one company in North London that you can trust for these services. Give them a call to find out their rates.


A Virtual Private Network (VPN) protects you online by encrypting all data transferring from your device to the Internet and back.
This means that no-one can snoop on your online activities, not even your Internet Service Provider.
Of course, if you login on social media, retail websites etc. they can track you on their sites.
This is especially important if you’re using public Wi-Fi as they can be used by criminals to collect data on you. Using a VPN protects against this.
A VPN will also hide your IP address. Many websites and streaming services use your IP address to control what you can access. Through a VPN you can choose to connect from a different country if you wish.
The Way a VPN Works
Essentially you connect to the VPN, to whichever of their hubs in whichever country you wish and all of your Internet traffic is directed through their servers where the data is encrypted. Likewise any traffic from the Internet returning to your is also encrypted.
You will appear to be connecting to the Internet at one of the VPN provider’s IP addresses.
Most VPN providers also have a ‘no logs’ policy whereby they don’t keep any records of the data through their system and hence even if hacked – nothing except your profile could be found.
Using a VPN may slow down your Internet access marginally but is unlikely to be an issue as VPN providers need to have fast systems to stay in business.
In practice the only noticeable difference for users of VPNs is that when starting up a PC the VPN will connect automatically so you can it.
If you have any experiences with these scams do let me know, by email.


The first Laptop networks were dedicated Unique-objective techniques which include SABRE (an airline reservation system) and AUTODIN I (a protection command-and-Handle system), each developed and carried out within the late 1950s and early nineteen sixties. From the early nineteen sixties Laptop companies had started to work with semiconductor know-how in commercial products, and each regular batch-processing and time-sharing techniques were in position in lots of significant, technologically State-of-the-art businesses. Time-sharing techniques allowed a computer’s sources being shared in fast succession with several consumers, biking from the queue of consumers so immediately that the computer appeared devoted to Every person’s jobs Regardless of the existence of many others accessing the system “concurrently.” This led on the Idea of sharing Laptop sources (identified as host personal computers or simply hosts) around a complete community. Host-to-host interactions were envisioned, in conjunction with use of specialized sources (which include supercomputers and mass storage techniques) and interactive accessibility by distant consumers on the computational powers of your time-sharing techniques located elsewhere. These Concepts were initially realized in ARPANET, which proven the initial host-to-host community link on October 29, 1969. It had been established through the State-of-the-art Exploration Projects Agency (ARPA) of the U.S. Office of Defense. ARPANET was on the list of initially normal-objective Laptop networks. It connected time-sharing personal computers at federal government-supported investigation web-sites, principally universities in America, and it before long grew to become a essential bit of infrastructure for the computer science investigation community in America. Equipment and applications—like the simple mail transfer protocol (SMTP, typically generally known as e-mail), for sending small messages, as well as the file transfer protocol (FTP), for for a longer period transmissions—immediately emerged. As a way to achieve Expense-productive interactive communications between personal computers, which typically communicate To put it briefly bursts of data, ARPANET utilized The brand new know-how of packet switching. Packet switching can take significant messages (or chunks of Laptop info) and breaks them into smaller sized, manageable items (often known as packets) that will vacation independently around any obtainable circuit on the target destination, wherever the items are reassembled. Thus, in contrast to standard voice communications, packet switching won’t demand a single dedicated circuit between Every pair of consumers. Business packet networks were released within the 1970s, but these were developed principally to deliver effective use of distant personal computers by dedicated terminals. Briefly, they replaced long-distance modem connections by significantly less-pricey “Digital” circuits around packet networks. In America, Telenet and Tymnet were two this sort of packet networks. Neither supported host-to-host communications; within the 1970s this was nonetheless the province of the investigation networks, and it will keep on being so for quite some time. DARPA (Defense State-of-the-art Exploration Projects Agency; previously ARPA) supported initiatives for floor-based mostly and satellite-based mostly packet networks. The bottom-based mostly packet radio system presented cell use of computing sources, while the packet satellite community connected America with several European countries and enabled connections with widely dispersed and distant areas. Using the introduction of packet radio, connecting a cell terminal to a computer community grew to become feasible. However, time-sharing techniques were then nonetheless far too significant, unwieldy, and expensive being cell and even to exist outdoors a climate-controlled computing atmosphere. A powerful drive So existed to connect the packet radio community to ARPANET to be able to allow for cell consumers with simple terminals to accessibility time-sharing techniques for which that they had authorization. Equally, the packet satellite community was employed by DARPA to connection America with satellite terminals serving the uk, Norway, Germany, and Italy. These terminals, having said that, needed to be linked to other networks in European countries to be able to reach the finish consumers. Thus arose the necessity to link the packet satellite net, along with the packet radio net, with other networks. Basis of the online world The world wide web resulted from the effort to connect several investigation networks in America and Europe. Initial, DARPA proven a program to analyze the interconnection of “heterogeneous networks.” This program, identified as Internetting, was depending on the recently released idea of open up architecture networking, by which networks with defined normal interfaces might be interconnected by “gateways.” A Doing work demonstration of the idea was planned. To ensure that the idea to operate, a whole new protocol needed to be developed and created; certainly, a system architecture was also expected. In 1974 Vinton Cerf, then at Stanford College in California, which author, then at DARPA, collaborated over a paper that initially described this type of protocol and system architecture—particularly, the transmission Handle protocol (TCP), which enabled differing kinds of equipment on networks all over the world to route and assemble info packets. TCP, which at first incorporated the online world protocol (IP), a world addressing system that allowed routers to obtain info packets for their ultimate destination, formed the TCP/IP normal, which was adopted through the U.S. Office of Defense in 1980. From the early 1980s the “open up architecture” of the TCP/IP solution was adopted and endorsed by a number of other scientists and finally by technologists and businessmen world wide. From the 1980s other U.S. governmental bodies were seriously involved with networking, such as the Nationwide Science Basis (NSF), the Office of Electrical power, as well as the Nationwide Aeronautics and Place Administration (NASA). Whilst DARPA had played a seminal position in making a smaller-scale Model of the online world among its scientists, NSF worked with DARPA to develop use of the whole scientific and educational community and to generate TCP/IP the normal in all federally supported investigation networks. In 1985–86 NSF funded the initial five supercomputing centres—at Princeton College, the College of Pittsburgh, the College of California, San Diego, the College of Illinois, and Cornell College. During the 1980s NSF also funded the event and operation of the NSFNET, a countrywide “spine” community to connect these centres. From the late 1980s the community was running at many bits per next. NSF also funded several nonprofit community and regional networks to connect other consumers on the NSFNET. A couple of commercial networks also started within the late 1980s; these were before long joined by others, as well as the Business World-wide-web Trade (CIX) was formed to allow transit targeted visitors between commercial networks that or else wouldn’t have already been allowed to the NSFNET spine. In 1995, immediately after considerable assessment of the specific situation, NSF made the decision that guidance of the NSFNET infrastructure was no more expected, considering that several commercial vendors were now eager and in a position to fulfill the demands of the investigation community, and its guidance was withdrawn. Meanwhile, NSF had fostered a aggressive collection of economic World-wide-web backbones linked to each other by so-identified as community accessibility factors (NAPs).

Green communications is the practice of selecting energy-efficient communications and networking technologies and products, and minimizing resource use whenever possible in all branches of communications. Green networking practices include: Implementing virtualization.
Energy crisis and rising concerns on Greenhouse Gas (GHG) emissions have always been crucial issues faced by the development of wireless communication techniques. As a more energy-efficient network architecture, green communications and networks (GCNs) have recently attracted significant attention from academia and industry. In particular, the newly designed GCN not only can alleviate the greenhouse effect and decrease the operational expenditure, but also can attain sustainable development due to the descending independence from fossil fuel and the exploitation of renewable energy resources. In order to enable the technical and economical GCNs, several emerging techniques have been proposed including energy-efficient and energy harvesting techniques. Although these emerging techniques have drawn considerable attention and have been studied recently, there are still many open theoretical and practical problems to be addressed. Specifically, most of the existing works have focused on optimizing a single objective of GCNs, such as energy efficiency. Since there are multiple conflicting objectives in GCNs (e.g., spectral efficiency and energy efficiency), multi objective strategies are required to be considered in order to achieve a good trade off among the conflicting objectives. Moreover, since non orthogonal multiple access techniques have advantages in energy efficiency and massive connectivity, how to apply non orthogonal multiple access techniques into GCNs needs to be further investigated. Furthermore, the conventional linear energy harvesting model is ideal in practice. How to design GCNs under practical nonlinear energy harvesting models is required to be focused on.
This special issue aims to provide a comprehensive overview of the state of the art in theory and practice for realizing GCNs, which will bring together researchers from academia, industry, and governmental agencies to promote the research and development needed to address the major challenges that pertain to this cutting-edge research topic.
Potential topics include but are not limited to the following:
- Multi objective resource allocation strategies for GCNs
- Multi objective optimization theory for GCNs
- Multi objective energy-efficient techniques for GCNs
- Energy-efficient cooperative techniques for GCNs
- Energy-efficient non orthogonal multiple access techniques for GCNs
- Practical energy harvesting models for GCNs
- Resource optimization for GCNs under practical nonlinear energy harvesting models
- Physical layer security techniques for GCNs
Multi antenna techniques for GCNs :
With the data traffic expected to grow nearly exponentially, concerns regarding excessive energy consumption in wireless networks have been also raised for home and enterprise environments. These two types of networks are discussed here jointly due to many similarities they exhibit, namely, similar propagation environments (dominantly indoor scenarios, high diversity of building structures with many obstacles, both due to wall construction and due to the used equipment), similar basis of a network structure, i.e., usually consisting of an Ethernet-based backbone and a wireless last hop where many different wireless technologies emerged. To complete the overview also the most important differences and future perspectives for both networks are pointed out. Then, the “green context” of the discussed environments is brought up. To this end, first the important metrics used in context of green networking in wireless scenarios are introduced, and using these metrics an initial evaluation of the potential energy savings in both scenarios is performed. Next, the energy savings that are possible to achieve in the current state of home and enterprise networks are surveyed. We start with an overview of what can be done, including hardware (room for possible hardware improvements) and network-level solutions, with a conclusion that the latter approaches have much more potential. Then, an overview of most important challenges and limitations in current home and network environments is provided. Next, a detailed survey of the network-level solutions applicable in dense WLAN scenarios is given, followed by an outlook on the deployment of photocells and their most important challenges in near-future perspective home and enterprise deployments.

Many experts agree that we should see the Industry 4.0 playing a bigger role in 2017. If you are thinking, “I want to get on board of that too”, but you are not sure how and where to start, you should read our posts. Since it’s such a new trend many people never heard of it. And those who did might not be exactly sure what it is.
In last week’s post, we shortly spoke about the origin and history of Industry 4.0. It is important to understand that this movement didn’t just pop out of nowhere but it is a natural progression of things. The next step of understanding Industry 4.0 is to learn what tools are used to implement this new trend.
Internet of Things
Not surprisingly, over 87% of people haven’t heard the phrase Internet of Things, although the term has been around for few years. What can surprise many is that a lot of us take advantage of IoT without even knowing it. According to Bryce Barnes, Internet of Things is an intelligent connectivity of smart devices by which objects can sense one another and communicate. In other words, the Internet of Things or IoT is a term that refers to machines, objects and devices that have the capability to connect to the Internet and collect and transmit data using the network. So when we are using our smartphones to send an email, or through our laptop, we are checking out our home security camera at home. We are taking advantage of IoT and are part of this concept. One of the first Internet of Things object was an ATM machine, and that was back in 1974. As you see, the concept isn’t new. It’s just been named and organised. Already in 2008, there were more objects connected to the Internet than there are people in the World. And in 2016 there were 4,9 billion things connected to the Internet. While experts estimate that in 20 years the IoT will add $10-$15 trillion to global GDP. By then the estimated number of deceives connected to the Internet should reach around 26 billion.
IoT in everyday life
As we mentioned before there are more IoT objects that one can apprehend. First devices that come to mind are our smartphones, laptops, computers or TVs. But there are so many Internet of Things objects that we use every day and don’t even realise that they are the part of this concept. Such devices or objects these might be: cars, ovens, home security systems, pulsometers or smartwatches.
Why IoT and Industry 4.0?
Of course, the concept of IoT and its benefits is much more complicated when it comes to Industry 4.0. It is one of core components of it next to cyber-physical systems and Internet of Service. Designing devices to work specifically to our needs and the needs of our company will require adjustment and often development of new protocols or software. Smooth communication reduces waste and speeds up the process of production. Internet of Things Objects can be implemented in many areas of business: manufacturing, transportation and logistics healthcare, media and much more.
Both Industry 4.0 and the Internet of Things are based on the similar concept: increasing interactions between machines, products and people in order to increase efficiency and adaptability. To achieve said goals the Industry 4.0 trend enlisted the help of IoT. Since both concepts can be used in virtually every field of business the chances are that your company can benefit from them too. Industry 4.0 and the Internet of Things are the way to move forward. Not only implementing the idea will help to reduce waste, it will also assure that your company is competitive and stays current to needs of your costumers.


Broadband access in the United States is not universal, with a longtime digital divide between urban and rural areas. But in one small town just four hours from Washington, D.C., there's no internet service at all, because Green Bank, W.Va., is the site of the largest fully steerable radio telescope in the world, so internet connections and anything else that can create electromagnetic waves are banned. VOA's Lesya Bakalets traveled to Green Bank as we see in this report narrated by Joy Wagner.

Can I Get Someone’s Name and Address from Their IP Address?
Instead, a colon is added to indicate the gap. Furthermore, some argue that IPv6 is a more efficient technology, providing better quality and connectivity. However, IPv6 has not been fully implemented for two reasons:.
IPv4 still suits our needs, and until we reach its limit, a worldwide shift is unlikely. The IP address provided by your internet service provider is also known as your public IP. Devices on the same network share this IP when accessing the internet. Take your home network for an example. Routers assign private IPs to each device on their network, so that devices can identify and find each other.
When these devices connect to the internet, their private IP addresses remain hidden, and only the public IP addresses of routers are visible. If you care about your privacy and security, you need to use a trustworthy VPN service.

Hi! My name is Chip, and I am licensed by the FCC as WRTY997 in the GMRS service. I am also an amateur radio operator licensed as N3FUD.
I became interested in Amateur Radio in 1980, but couldn’t master the 5wpm morse code requirement needed for a Novice class license until 1984 when the PA Air National Guard sent me to specialized training just for morse code (kind of a do or die situation). I became KA3NDC and held my Novice license for only a short time before I moved up to Technician, and became N3FUD. When the FCC did away with the code requirement, I moved up to the Tech+ level. I mainly inhabited the 2m and 70cm bands but lost interested in the late 1990s due to several family and health issues. I obtained my General License on May 11, 2006, at the York Ham Foundation test.
I had heard of GMRS back in the 1990’s, but at that time, it seems very limited as it seemed to be business related or family groups. Besides, I had amateur radio; that was enough communications for me.
Fast forward to 2022. A coworker mentions GMRS as another tool in the emergency communications tool box. I looked into it again and found out that the FCC had basically returned the 10 year license fee to $35. I found GMRS repeaters and groups had flourished, and there was a decent amount of repeaters in the Harrisburg, Pennsylvania area. A little more research showed the amount of repeaters in southeast and southwest Pennsylvania had significantly increased.
Additionally, it appeared that repeaters could be linked together to expand coverage across the Commonwealth. However, there seems to be two interpretations of Part 95. One hypothesis is that the only reason repeaters should be linked to anything is for repeater control. The other hypothesis is that as long as the repeaters are not links by wireline (hardline), they can be linked together. The FCC is currently revising Part 95, so many repeater owners are waiting for the latest version. (You will note that the comments are turned off for this topic. I have seen too many arguments over which hypothesis is correct.)
In my research, I found that there are many systems available to link repeaters and simplex nodes together. Many states and areas have created their own systems. One common part of these systems is the linking software; most systems are using AllStarLink, which was developed for Amateur Radio repeater linking. It’s an easy system to set up and use.
There seems to be three major organizations promoting and linking GMRS repeaters. GMRS Live has several area networks linked together. myGMRS has a few area systems linked together and provides regional hubs to connect to. USGMRS is more of a supporting organization, but they may have a system to link repeaters together; they also have a annual membership fee which is a bit high unless you’re an organization that can afford it.
After all of my research, it appears GMRS Live is the better system provider with more nodes and fast response times. They have a system of administrators and moderators that control the system. myGMRS took about six weeks to answer my request for a node number. GMRS Live issued me five node numbers in less than 48 hours.
I am attempting to set up a Pennsylvania GMRS linking system while I eagerly await the FCC’s upgrade to Part 95. The system will use GMRS Live as the basic system,

Become one of the best substitutes in the market
Yes, Cat5e can do PoE (Power over Ethernet).
PoE (Power over Ethernet) allows cat5e patch leads and cat5e bulk cable to provide electric power as well as a data connection to devices such as switches, HDMI extenders, IP cameras, and routers.
There are three ways a cat5e cable will deliver PoE: Alternative A, Alternative B, and 4PPoE.
Alternative A transports power on the same wires as data for 10 and 100 Mbit/s ethernet variants.
Alternative B transports the power on separate pairs, meaning the data and power are separated into 2 different pairs, making troubleshooting easier.
4PPoE provides power on all four pairs of twisted cables. This enables the cable to provide power for higher power applications.
