Co channel cells free
To find the nearest cochannel neighbour of a cell move i cells along any chain of hexagons, turn 60 o anticlockwise and move j cells. There are at most 6 nearest cochannel cells. Cell Cluster with K 7 i j. This preview has intentionally blurred sections.

For hexagonal cells, i. e. , with 'honeycomb' cell layouts commonly used in mobile radio, possible cluster sizes are C i 2 ij j 2, with integer i and j (C 1, 3, 4, 7, 9, ). Integers i and j determine the relative location of cochannel cells.
cell divided into 3 (120o sectoring) or 6 (60o sectoring) equally sized sectors Frequenciestraffic channels assigned to cells must partitioned into 3 or 6 disjoint sets Reduces the number of cochannel cells causing interference Disadvantages: need intracell handoff, increases complexity
tier approximation may be sucient. Recall the procedure for locating cochannel cells introduced In reality, the actual signal strength needs to be also considered. This is especially true when noise, in addition to cochannel interference, is considered.
