METHOD AND SYSTEM FOR REDUCING WIRELESS MULTI-CELL INTERFERENCES THROUGH SEGREGATED CHANNEL ASSIGNMENTS AND ANTENNA BEAMS

摘要

A method and system for reducing multi−frequency signal interference consisting dividing an available frequency spectrum into a plurality of channels(channel 1−n),a first wireless coverage unit is then segregated into a first number of geographical segments and second number of channel blocks(block 1),each channel block(block 1)is assigned to at least one of the segregated geographical segments with predetermined priorities.The above steps are repeated for each neighboring area of the first coverage unit,wherein the channels(channel 1−n)in different channel blocks(block 1)exhibit no higher mutual interference than the channels in the same channel block(block 1),and wherein the channel block(block 1)assigned for each segregated segment of the first coverage unit is different from the channel block assigned for the segregated segment of a second coverage unit that immediately borders with the segregated segment of the first coverage unit even if the first and second coverage units share the same frequency spectrum.
