On the relationship between geostationary orbit capacity and the interference allowance

A discussion is conducted concerning the impact which may be anticipated from an increase of the intersatellite interference allowance in the geostationary orbit which would permit a greater number of satellites to be accommodated within that orbit/spectrum resource. Since the individual satellites' capabilities will be reduced as a result of such a change, attention is given to the tradeoff between intersatellite interference and total orbit capacity for both digital and analog modulation methods.
