Two satellite communications systems can use the same frequency or frequenci es in geographically overlapping footprints, without creating undue interferenc e in a given system that is caused by the same frequency signal(s) that is/are used by the other system. In particular, an aggregate Effective Isotropic Radiated Power (EIRP) of the radioterminals and/or ancillary terrestrial components of a second satellite communications system in the common footpri nt is sufficiently low, and/or the receive antenna gain of a first satellite communications system is sufficiently low compared to the receive antenna ga in of the second satellite communications system, so as to increase an aggregat e receiver noise that is seen by the first satellite system receivers by an amount that does not substantially change a Quality of Service (QoS) of the first satellite communications system. |
