ATPC (Automatic Transmission Power Control)
Maximum ATPC range 40 dB – This range is limited by the
amount of fixed attenuation with
respect to the nominal TX power
Power Control Criteria Remote terminal Received Signal
Level (RSL) and BER
Aim To counteract the effect of flat
fading, minimizing nodal interferences
