Frequency Reuse is the plan wherein assignment and reuse of channels throughout a coverage region is done. This plan likewise improves on RF planning–one requires only to assign segments to sectors while utilizing a similar RF channel among every single base-station. It diminishes inter-cell interference and limits the outage area. Each cellular base station is allocated a group of radio channels or Frequency sub-bands to be utilized inside a small geographic area known as a cell. The shape of the cell is Hexagonal.
