CONFIDENTIAL D-620003-0-20 Rev J
Table 6-32 shows the capacities of both 800 and 1900 MHz Unison systems used for
single and multiple protocol applications. The power per carrier for each system is
based on providing equal coverage areas for both systems when they are used in an
office building that is 80% cubicles and 20% offices.
Note 1
The RF channel capacity limits are based on the Unison data sheets’ “typical” specifications for fiber length, Cat-5 length, and RF perfor-
mance.
Note 2
The subscriber capacity limits are based on the Erlang B traffic model with a 2% GOS. Each user has a 50mErlangs, which is higher than
the standard 35mErlangs.
