120o sectoring

60o sectoring

microcell

Cell Sectoring :

• R : unchanged, Q=D/R : decreasing

• using directional antenna

• the co-channel interference is reduced

• assume 7-cell reuse for 120o sectoring, the number

of interferes is reduced from 6 to 2, all 6 co-channel

cells would interfere with the center cell for omni antenna.
