Abstract

The performed study is an up-link carrier to interference (C/I) performance evaluation of narrow multibeam and wide sector-beam node antennas in a PMP system. It is shown that the introduction of three-beam node antennas improves up-link C/I with 5 dB compared with wide-beam sector antenna. The replacement of wide-beam antennas can be made on a sector by sector basis. Simulations have shown that it is possible to get significant interference improvement in a 5×3 hub network by replacing 20% of the wide-beam antennas with multi-beam antennas.
