CTPhone 1900 System Planning
Base Station Broadcast Range
In a typical office environment, each base station has a broadcast range of
100 meters (328 feet) and supports an area of 31,000 square meters. The
range may increase to a maximum of 1000 meters (3280 feet) outdoors.

Traffic Guidelines
Each eight-channel base station supports eight simultaneous conversa-
tions (each “Mini” base station supports four simultaneous conversations),
but because all users are not in constant conversation, a base station can
support a greater number of CTPhone handset users.
For example, two base stations (BS1 and BS2) are required to support 32
CTPhone handset users in the factory area in the site illustrated in Figure
2-6.
