The technology has advanced a lot and there are many special features in every mobile set. Apart from the mobiles there are telephone mobil in the markets. The telephone mobil is a portable device that does stay fixed at one place but can be taken from one place to another. It is in the form of a telephone only but it can be taken to places. This is possible due to the radio waves that enable the transmission to these phones. The telephone mobil is connected to two types of network.

In the year 1915, the America telephone and telegraph department were interested in taking out wireless phones but were afraid that it would push the simple phones out of the market. In the year 1946, the MTS system was introduced in which the customer has to call the operator of the telephone mobil in order to call to any other person. Later on the AT & T introduced the phones that worked on the basis of radio waves. Now everything has advanced to such a great extent that there is the facility of Internet connection and wireless emails on the phones. With time many companies have launched their telephone mobil in the market and are selling them. Many people opt for these gadgets, as they are more handy and conspicuous. 

Earlier the telephone mobil were very large in size and heavy as well. These telephones send and receive radio signals with any number of cell site base stations that have microwave antennas. This is represented in form of hexagonal shapes on the maps. The telephone mobil do have low power transceiver that sends the voice and data to the nearest cell sites (about 8 to 13 km). But with time this has been overpowered by latest technology.
