Creating a Network with Cells
Cells or data nodes can be created with AWE units to maxmimize coverage, minimize interference, and
increase data throughput. Directional antennas are mounted on a mast to divide cells into sectors.Each sector
is connected to an antenna and a base station. Directional antennas increase signal gain within the sector and
increase the distance possible between base stations and remotes. Center frequency, acquisition code and
antenna polarization techniques are used to isolate sectors. The increase in data rate depends on the number
of sectors. For example, the data rate of Cell 1 in the diagram below is 36 Mbps (12 Mbps x 3 sectors). Cells
are distributed across a service area and can be linked to each other via a wireless link or a fiber optic cable.
LAN with Cells and Sectors

Wireless Link
Cell 1
Cell 2
In this example, cells are divided into120 degree sectors.
Cells are linked to other cells by a wired or wireless link.
