6.6.1 Connecting Multiple Main Hubs
You can use power combiner/splitters as splitters to connect multiple Main Hubs in
order to increase the total number of RAUs in a system. You can also use power com-
biner/splitters to combine base station channels in order to increase the number of RF
carriers the system transports.
The following figure shows connecting two Main Hubs to a simplex repeater or base
station. Connecting two Main Hubs increases the total number of supportable RAUs
from 32 to 64. Two Main Hubs support up to 8 Expansion Hubs which in turn support
up to 64 RAUs.
