The very first transmission of radio includes a wireless telegraphy or Morse code that is made by an electrical engineer and Italian inventor named Guglielmo Marconi in the year 1985. He is popular for his original work in terms of radio transmission through long distance and also because of his system of radio telegraph and his improvement of the Marconi’s law. Frequently, he is also credited or recognized as the discoverer of radio. There are also some people who also work on it, including James Clerk Maxwell, Alessandro Volta, George Ohm, and Andre-Marie Ampere.

The broadcast radio network type is a system network that distributes the programming to several stations at the same time, or sometimes delayed in several seconds, for its purpose of lengthening the total coverage outside the limits or restrictions of a solo broadcast signal. As a result, there are expansion to audience or the information or radio programming and essentially applies all the benefits or advantages of the mass production towards broadcasting enterprise. Radio network have two different sales departments, the first one is to pack and sells the programs to the stations or radio, and the other one is to sell audiences of a certain programs to the advertisers.

Almost all of the networks of radio also make most of their own programming. Originally, the radio networks own most or even all of stations that broadcast a networks programming radio format. However, in these present days, much of the radio networks that does not have their very own station but still distribute or produce programming. Likewise, station ownership doesn’t always specify network affiliation. The network company may have their own radio stations in numerous markets, they can also purchase a programming from different networks variety.

In the year 1920, the radio networks rapidly rose because of the growth in the regular broadcasting for the listeners in their home, the growth took countless paths in plenty of places. The BBC or the British Broadcasting Corporation in Britain, was established with the use of public cash, in the method of broadcasting monopoly and broadcast receiver license during its early years. In contrast, there are various networks for commercial broadcasting that are competing with each other and funded by the advertising revenue in United States. Because of it, the same company or corporation that operated or owned the network frequently marketed and manufactured the listeners of the radio.

There are major technical hindrances or challenges that needs to be passed when allocating programs most especially through long distances or far places, because it needs to maintain a high quality signal and to manage the amount of relay and switching points that are used in the signal chain. During the early years, programs were being sent to the remote station, either affiliated o owned, using different kinds of methods, including the use of audio tape, gramophone records that are pre-recorded and rented telephone lines.

The world’s very first non-wire line all-radio was the Rural Radio Network, it is a combination of six different upstate FM station in New York that began their operation in the month of June at the year of 1948. The microwave terrestrial relay is a technology which is later presented to the link stations, microwave terrestrial relay have been supplanted largely by the satellite, fiber, and coaxial cable, which normally offer a superior benefit ratios. There are also many early networks of radio that became a Television networks these days.

There are only two kinds of radio network that are being used in this world, the first one is the one-to-many broadcast network and the other one is the two-way radio type. The one-to-many type of radio networks are usually used for entertainment in mass media and for the public information. While the two-way type of radio networks are usually used for the public services like police, taxicabs, fire and delivery services, two-way type of radio networks are also used for public safety. Cellular phones has the capability to receive and to send messages all at once by making use of two different kind of frequencies at an identical period of time. Much of the similar components and basic technology works on all three.

The two-way kind of the radio network has many similar components and technologies like the broadcast kind or type of radio network. However, it is generally made with a fixed broadcast transmitters or points together with a mobile transmitters and receivers or also known as the transceivers and with receivers that are co-located. Because of it, both the mobile and fixed radio units can communicate to each other even over broad geographical regions that are ranging in size from single and small cities to the entire provinces and states and countries.

There are also many ways for the multiple fixed receive and transmit sites to be interconnected to each other to accomplish the coverage of range that is needed by the authority or jurisdiction who are applying the systems, such as the fibre-optic links, conventional wireless links that are used in several bands of frequency or the micro-wave links. In almost all of those cases, a signal is usually backhauled to the central adjustment of some the type where messages in radio are resent and processed repeatedly to all of the transmitter sites to where it’s required for the people to be heard.

In modern, the two-way systems of radio is a concept that are called as trunking. It is usually used to accomplish a better effectiveness of the use of radio spectrum, it also provide a very widespread ranging coverage that doesn’t required any switching channels by the user of mobile radio when it roams within the coverage of the system. The trunking of the two-way systems of radio is the same to the idea that is used for the cell phone systems, in which each of the mobile and fixed radio is precisely recognized to the controller system and the operation used can be switched or changed by the user or controller.
