1. A radiotelephone system comprising:

  • a wireless network that is configured to communicate bidirectionally with a plurality of radiotelephones using at least one air interface protocol and a frequency; and

    an aggregate radiated power controller that is configured to limit an aggregate radiated power by the plurality of radiotelephones that use the at least one air interface protocol and the frequency by controlling at least one of the radiotelephones to use another frequency that has not exceeded its maximum aggregate radiated power;

    wherein controlling at least one of the radiotelephones to use another frequency that has not exceeded its maximum aggregate radiated power comprises;

    the aggregate radiated power controller evaluating an expression that depends upon a structural attenuation margin that is provided to the at least one of the radiotelephones by the wireless network; and

    the aggregate radiated power controller controlling at least one of the radiotelephones to use another frequency that has not exceeded its maximum aggregate radiated power, responsive to the evaluating an expression that depends upon a structural attenuation margin that is provided to the at least one of the radiotelephones by the wireless network.
