Abstract :
This paper presents a modified N=9 frequency plan for OMNI and 60-STSR (60 degree, Sector Transmit and Sector Receive) cell sites. It is based on dividing all the available channels into 9 or multiples of 9 groups. The basic N=9 cell cluster uses an ODD/EVEN channel distribution scheme which forms a 3 × 3 array of nine frequency groups. The proposed plan is free of adjacent channels and enhances channel capacity by a factor of 2.3 in AMPS, 6.9 in TDMA-3 and 13.8 in TDMA-6
