AB  - The wireless technology is growing very quickly,
in the actuality the new technologies applied
to the radius link appear with a multiplicity of
names that change as the application and the use
that do of them: Bluetooth, GSM, Microwaves,
Links Satellites, Wi-Fi, WiMax, ZigBee, etc. Each
system uses a hardware and devoted software and
exclusive chord to his functionalities to send and
receive the waves of radio. Some of these bands
of the spectrum can justify by the fact that some
applications work better in determinate spaces
inside the spectrum electric radio. This exponential
growth of wireless applications creates an every
time main demand of spectrum electric radio what
has motivated the research of technologies of
radio that can scalar to satisfy the future demands,
so much in terms of efficiency of spectrum and
performance of the applications
