Maximum Output Power per Carrier
6.3.1 2500 MHz WiMAX
Designing for Capacity Growth
Fusion Wideband systems are deployed to enhance in-building coverage and/or to
off-load capacity from a macro cell site. In many instances, subscriber usage
increases with time and the wireless provider responds by increasing the load on the
installed Fusion Wideband system. For example, the initial deployment might only
require two RF carriers, but four RF carriers may be needed in the future based on
capacity growth forecasts. There are two options for dealing with this scenario:
1. Design the initial coverage with a maximum power per carrier for four RF carri-
ers. This will likely result in additional RAUs.
2. Design the initial coverage for two RF carriers, but reserve RAU ports on the Hub
for future use. These ports can be used to fill potential coverage holes once the
power per carrier is lowered to accommodate the two additional carriers.
