◦ RSSI of -67 dBm for all data rates should be the goal for 11b/g/n and 11a/n
◦ SNR should be 25 dB for the data rate used by client to connect to the AP
◦ Packet error rate (PER) should be configured for a value of one percent or less
◦ Channel with the lowest utilization (CU) must be used
Check the CU when no traffic is running
◦ Radio resource manager (RRM) can be used to implement the recommended RSSI, PER, SNR,
CU, cell coverage, and coverage hole settings on the 802.11b/g/n radio (RRM is not available on
802.11a/n radio).
