System Gain

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.
6.4 System Gain
The system gain of the Fusion defaults to 0 dB or can be set up to 15 dB in 1 dB
increments. In addition, uplink and downlink gains of each RAU can be indepen-
dently attenuated by 0 or 10 dB using AdminBrowser.
The recommended maximum lengths of CATV cable are as follows:
• For RG-59 cable 150 meters for CommScope PN 2065V.
• For RG-6 cable 170 meters for CommScope PN 2279V.
• For RG-11 cable 275 meters for CommScope PN 2293K.
If the maximum distance is not required, then copper-clad over steel center-conductor
cable may be use to reduce cable costs.
If the CATV cable is longer than the recommended distance per cable type, the gain
of the system will decrease, as shown in Table 6-7 and Table 6-8.
