ABSTRACT:
A pattern and a method of establishing a pattern of microcell base station antennae in dense urban areas. The base station antennae are each configured to transmit on one of several sets of frequencies, and are placed at intersections on a grid of horizontally parallel and vertically parallel streets. The pattern distributes the antennae in two separate repeating sequences running diagonally on the grid. By using tall buildings between the streets as propagation blockers, the pattern optimizes the use of a limited number of allocated frequencies and minimizes co-channel and adjacent channel interference.
