Increasing channel capacity of wireless local loop via polarization diversity antenna distribution scheme

摘要

In order to increase the channel capacity of a wireless local loop network, advantage is taken of the fixed location of each subscriber radio, and the ability to independently configure each subscriber's antenna, to provide antenna cross polarization isolation into the cellular layout of the WLL network, and thereby provide an additional layer of interference rejection. Such a cross polarization assignment scheme, in combination with frequency reuse allocation, provides a substantial increase in the C/I ratio and thereby allows an expansion of the reuse of frequency channels.
