Symptom

C9120AXI using the same channel, the same bandwidth, the same transmission power signal strength is weaker than AP2802I The two aps are registered in the same WLC9800 to ensure that the configuration is the same. Comparing the test results, the signal strength of the 9120 is weaker than that of 2802 Using the 9130 simulation client, run the show RRM neighbor-list command to check the signal strength of 9120 and 2802

Conditions

C9120AXI using the same channel, the same bandwidth, the same transmission power signal strength is weaker than AP2802I The two aps are registered in the same WLC to ensure that the configuration is the same. Comparing the test results, the signal strength of the 9120 is weaker than that of 2802

Workaround

Increased the TPC power level
