FWT Introduction
The Motorola
Fixed Wireless Terminal (FWT) communications device is
used for connecting into the local telephone network; it is an RF
transceiver which allows a standard telephone set to be used to access
the CDMA (IS–95–A or J–STD–008) cellular air interface. The desktop
or wall–mounted indoor unit is designed for use in areas where wired
service is not available or where wireless service is otherwise preferred.
The FWT is available in two models – one supports 800 MHz
frequencies; one supports 1.9 GHz frequencies. Figure 1 illustrates how
the FWT is integrated into the CDMA cellular system architecture.

The FWT provides a link to the local telephone exchange. Subscribers
receive the same set of features typically offered by the local telephone
service provider to ‘wired’ customers.
Via the FWT’s single RJ–11 telephone jack, up to three parallel
electromechanical ringer style telephones, or five electronic ringer
telephones may be connected at a distance of 100 meters from the unit.
However, during a conversation with another party, no more than two of
the phones at a FWT site can be off–hook at a time. Using more than 2
telephones will not damage the FWT but may result in decreased, or
non–performance of one or more telephones connected to the FWT.
