In cellular telephony, a plurality of communication signals which are received at a base station for wireless transmission are multiplexed onto a single physical medium which runs up a mast. This reduces the use of cabling running up the mast with an attendant savings in cost.

Cellular telephony mast cable reduction

A millimeter-wave point-to-multipoint LMDS radio system for broadband wireless access having frequency reuse that includes a cell area divided into an integer number k sub-sectors of equal angular arc 360/k degrees each; a hub having antennas each configured to generate an antenna beam that covers an integer number j sub-sectors, an angular gap i being defined between edges of coverage of one of the antennas where i is an integer number of sub-sectors; a total integer number of n channel sets each of at least one radio channel and each configured independent and free of interference from other ones of the channels in other ones of the channel sets, each of the channel sets having a number of uses defined by a quantity k/(i&plus;j) that is an integer equal or greater than two, each channel set being deployed with a common re-use pattern with an angular stagger between antennas of (i&plus;j)/n sub-sectors.
