Configuring Advanced Settings
The network profiles provide a web page for setting QoS, bandwidth, and power
settings. The Traffic Specification (TSPEC) parameters are used to advertise
information about generated traffic for Call Admission Control (CAC) to the AP.
Minimum PHY rate—Lowest rate that outbound traffic is expected to use before
the phone roams to another AP
Surplus Bandwidth Allowance—Fractional number that specifies the excess
allocation of time and bandwidth above application rates required to transport a
MAC service data unit (MSDU) in a TSPEC frame.
Note If your wireless LAN has access points that use 802.11b and you plan to use Call
Admission Control (CAC) with TSPEC, then you need to modify the PHY rate to
a supported rate for your 802.11b access points.
To make changes to the advanced settings, follow these steps:
Procedure
Step 1 Choose the network profile that you want to configure.
Step 2 Click the Advanced Profile link at the top of the page.
Step 3 In the TSPEC Setting area, keep the Minimum PHY Rate: 12 Mbps
Note If you are using 802.11b APs and plan to use Call Admission Control
(CAC) with TSPEC, then set the PHY Rate to a rate that the APs support
such as 11 Mbps.
