The following table shows the capacities of both 800 and 1900 MHz Unison systems
used for single and multiple protocol applications. The power per carrier for each sys-
tem 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 Cat-5 length and RF performance.
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.
