Can a complete wireless network live up to the expectations of a number of companies?

The need of communication with points found beyond the horizon and without the support of telecommunications wires for the transmission of information, was not regularly created short afterwards the discovery of wireless distribution, around in the dues 1800. The first system of mobile telephony was installed by the Marconi at 1898 in the island Wight of England, on behalf of the King Vi

It must be marked that the waves with lower frequencies can penetrate buildings, while the waves with high frequencies cannot. The how much information, now, can be transported from a wave it depends from his width. Thus in the low frequencies we can code few bits per Hertz, but often, up to 40 bits per Hertz in the high frequencies and under certain treaties. As long as wider the spectrum is so much bigger size of data can pass.
