Access Point Configuration
Radio setting 802.11b or 802.11g
When using the 802.11b/g band for the VoWiFi network, set the radio settings to 802.11b/g
mixed mode.
Preamble settings
The tests on the Aruba system were run with the short preamble setting.
The short preamble setting can be used, as this supports both short and long
preambles. Wireless IP Telephones only support long preamble.
When using a dual-radio AP, use the 802.11a radio for data and 802.11b/g for
voice if possible, as this will improve the overall performance.
