A cellular radio base station arrangement has a plurality of r.f. transceivers TX each for transmitting and receiving r.f. signals to and from antenna arrays 28 via respective transmit and receive feed means for one or more calls. The arrangement includes means 32 for monitoring the effective isotropic radiated power (EIRP) at the antennas. A communication link transfers the detected antenna transmit power levels to the r.f. transceivers where adjustment means 82 vary the power levels fed to the antennas to maintain the EIRP within maximum permitted levels. <IMAGE> |
