Configuration Guide

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. SpectraLink Wireless Telephones only support long preamble when using the 802.11b radio.

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.

Channel and Tx power

Channel and Tx power level can be manually set or configured to be assigned automatically depending on the RF environment. Please consult your facility’s RF site survey designed for voice to determine the correct channel, power and data rate settings. SpectraLink Wireless Telephones require the following minimum dBm reading to support the corresponding “Required” data rate setting in the access point.
