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.
