Abstract:
1. A satellite radiotelephone system comprising: a space-based component that is configured to communicate with a plurality of radiotelephones over a plurality of frequency bands and/or a plurality of air interfaces; an ancillary terrestrial network that is configured to communicate terrestrially with the plurality of radiotelephones over substantially the plurality of frequency bands and/or substantially the plurality of air interfaces; and an aggregate radiated power controller that is configured to control the plurality of radiotelephones and/or the ancillary terrestrial network so as to limit an aggregate radiated power by the plurality of radiotelephones to a maximum aggregate radiated power; wherein the plurality of frequency bands and/or the plurality of air interfaces comprise a GSM air interface and a CDMA air interface and wherein the aggregate radiated power controller is configured to control the plurality of radiotelephones and/or the ancillary terrestrial network, so as to limit the aggregate radiated power by the plurality of radiotelephones to a maximum aggregate radiated power substantially according to the following: where N GSM denotes a number of co-frequency time slots that are using the GSM air interface and N CDMA denotes a number of co-frequency codes that are using the CDMA air interface.
