Base Stations

The Base Station, as shown in Figure 3, transmits call information between the
Controller and the portable. The Base Station is connected to the Controller
using standard telephone wiring. The Base Station uses a wireless connection
(radio) to communicate with the portable.

Radios and antennas

The Base Station has two radios, each with two internal antennas and one
external antenna port. Using the two internal antennas one at a time, the radio
selects the internal antenna that has the best signal strength. This process is
antenna diversity.
The external antenna ports for each Base Station radio can be connected to
external antennas by coaxial cables. In this case, the installer configures the
radios to use only the external antenna ports and there is no antenna diversity.
