Maximum Output Power per Carrier
The following tables show the recommended maximum power per carrier out of the
RAU N connector for different frequencies, protocols, and numbers of carriers. These
maximum levels are dictated by RF signal quality and regulatory emissions issues. In
general, as the number of RF carrier increases, the maximum power per carrier
decreases. If these levels are exceeded, signal quality will be degraded and/or regula-
tor requirements will be violated. The maximum input power to the Hub is deter-
mined by subtracting the system gain from the maximum output power of the RAU.
System gain is software selectable from 0 dB to 15 dB in 1 dB steps.
Additionally,
both the uplink and downlink gain of each RAU can be reduced by 10 dB in 1 dB
steps.
When connecting a Hub to a base station or repeater, attenuation on the downlink is
typically required to avoid exceeding Fusion SS’s maximum output power recom-
mendations.
WARNING:
Exceeding the maximum input power may cause perma-
nent damage to the Hub. Do not exceed the maximum composite input
power of 1W (+30 dBm) to the Hub at any time.
NOTE:
These specifications are for downlink power at the RAU output (excluding
antenna).
