EDCA Parameters
Set the EDCA profile for Voice Optimized and disable Low Latency MAC for either 5 or 2.4 GHz depending on which
frequency band is to be utilized.
Low Latency MAC (LLM) reduces the number of retransmissions to 2-3 per packet depending on the access point platform, so
it can cause issues if multiple data rates are enabled.
LLM is not supported on the Cisco 802.11n/ac Access Points.
DFS (802.11h)
In the DFS (802.11h) configuration, channel announcement and quiet mode should be enabled.
Power Constraint should be left un-configured or set to 0 dB as DTPC will be used by the Cisco IP Phone 8800 Series to
control the transmission power.
