Frequency plan for a cellular network |
摘要 |
An N=3 frequency plan for 60 degree sector transmit sector receive (STSR) cell sites is based upon dividing available channels into 18 frequency groups. Frequency assignment is in accordance with an odd-even cyclic distribution of channels which provides a three-channel separation between sectors within a cell and at least seven-channel separation between adjacent cells. This ensures adequate channel isolation between sectors and improved adjacent channel C/I performance throughout the network. The N=3 frequency plan increases channel capacity by approximately 38% in AMPS and 114% in TDMA-3.
