Ecology and sanitary

The issues of ecology and sanitary applied to radio systems of massive use are becoming increasingly actual. Wide and ubiquitous implementation of these systems leads to the emergence of unwanted side effects related to the contamination by electromagnetic emission. There is a real need to reduce the emission level. The adaptive antenna array technique used in the McWiLL wideband access system makes it possible to reduce the transmission power by order of magnitude through the forming of partial patterns of base station antennas directed immediately to each active subscriber.
