A method and system is disclosed for reducing multi-frequency signal interference
in a wireless communication network. An available frequency spectrum is divided
into a plurality of channels, a first wireless communication coverage unit is then
segregated into a first number of geographical segments. After the segregated channels
are grouped into a second number of channel blocks, each channel block is assigned
to at least one of the segregated geographical segments with predetermined priorities.
All the above steps are repeated for each neighboring wireless communication coverage
unit of the first wireless communication coverage unit, wherein the channels in
different channel blocks exhibit no higher mutual interference than the channels
in the same channel block, and wherein the channel block assigned for each segregated
segment of the first wireless communication coverage unit is different from the
channel block assigned for the segregated segment of a second wireless communication
coverage unit that immediately borders with the segregated segment of the first
wireless coverage unit even if the first and second wireless communication coverage
units share the same frequency spectrum.
