The first system of mobile telephony was installed by the Marconi at 1898 in the island Wight of England, on behalf of the King Victoria’s. It deserves here to mark that the modern wireless digital communication began from the islands of Hawaii where the telephone system was insufficient and should is found certain other solution. Short afterwards the Second World War, the Laboratories Bell (Bell Laboratories) undertook a program for benefit of communication services with systems which used common institution (common carrier), so that are served a lot of users together moved in different geographic bands.
