multiple CPEs the “Max. initial ranging RSSI (dBm)” setting may need to be
reduced. This setting is available in the interfaces tab in AirConsole for the Base
Station’s bs_ofdm0 interface using the RNG_GRP sub-tab. Using your link budget,
calculate a reasonable maximum (about 5dB above your best link) and enter this
value in dBm. For example for short links anticipated at the highest throughput a
value of -65dBm (the default of -60dBm) may be appropriate. The Max. initial
ranging RSSI (dBm)” is used by the pBS to dynamically adjust each CPE transmit
power to balance the received energy in the pBS for each frame.
