Systems and methods for modifying antenna radiation patterns of peripheral base stations of a terrestrial network to allow reduced interference

A method of providing communications for radioterminals, the method comprising:

• providing communications service for radioterminals at an interior portion of a terrestrial network coverage area using interior base stations;
• and
• providing communications service for radioterminals at a peripheral portion of the terrestrial network coverage area using peripheral base stations, wherein at least one of the peripheral base stations provides transmissions directed toward an interior portion of the terrestrial network coverage area with greater power than transmissions directed away from interior portions of the terrestrial network coverage area.

A terrestrial communications network that is configured to wirelessly communicate with a plurality of radiotelephones, the terrestrial communications network comprising:

• a plurality of base stations that are configured to wirelessly communicate with the plurality of radiotelephones, the plurality of base stations including at least one base station having a return link margin greater than a forward link margin over at least a portion of a coverage area thereof.
