Cellular frequency reuse cell plan |
摘要 |
A frequency reuse plan for a cellular radio communications system includes a plurality of antenna sites which implement twelve groups of frequencies among four antenna sites. The same frequencies are reused by other groups of four antenna sites. Each antenna site serves three hexagon shaped cells arranged in a clover-leaf shaped pattern by three groups of antennas, each of which group is separated by a pointing angle of 120 degrees.
