5.2.3 Set Transmitted Power Level
It is good practice to match received power levels by adjusting transmitted powers if
co-located systems are being installed. This is important to avoid interference
between co-located systems. An attenuator can be fitted between the RF Unit and the
antenna if the power level cannot be sufficiently reduced. The dBm output at the RFU
N-type connector (socket) levels are set via the NMS or using a SNMP Management
application.
