<p>An improved cellular communication network which is divided into a plurality of cells is provided. Each of the cells including a base station has at least two directional antennae, each of which is operative to communicate with a plurality of units. Each of the antennae is directed in a different direction and operates in a different frequency band. A characterisitic of the cellular network is that antennae, in adjacent cells, operating in similar frequency bands are directed in different directions.</p> |
