802.11 Network Settings - Cisco 6861 Deployment Manual

802.11 Network Settings

We recommend that you have the phone operate on the 5 GHz band only due to that there are many channels available on
this band and not as many interferers as the 2.4 GHz band has.
To use the 5 GHz band, ensure that the 802.11a/n network status is Enabled.
We recommend that you set 12 Mbps as the mandatory (basic) rate and 18 Mbps or higher as the supported (optional)
rates. However, some environments may require 6 Mbps to be enabled as the mandatory (basic) rate.
When using the 5 GHz band, up to 12 channels only is recommended to avoid any potential delay of access point
discovery due to having to scan many channels.
For Cisco Autonomous Access Points, select Dynamic Frequency Selection (DFS) to use auto channel selection.
When DFS is enabled, enable at least one band (bands 1-4).
You can select Band 1 only for the access point to use a UNII-1 channel (channel 36, 40, 44, or 48).
Individual access points can be configured to override the global settings to use dynamic channel and transmit power
assignment for either 5 GHz or 2.4 GHz depending on the frequency band to be used.
Other access points can be enabled for Auto RF and workaround the access points that are statically configured.
This may be necessary if there is an intermittent interference present in an area.
The 5 GHz channel width can be configured for 20 MHz or 40 MHz if using Cisco 802.11n Access Points and 20 MHz,
40 MHz, or 80 MHz if using Cisco 802.11ac Access Points.
It is recommended to use the same channel width for all access points.
Ensure Client Power is configured properly. Do not use the default setting of Max power for client power on Cisco
Autonomous Access Points because that will not advertise DTPC to the client.
Enable Dot11d for World Mode and configure the proper Country Code.
Ensure Aironet Extensions is enabled.
Set the Beacon Period to 100 ms and DTIM to 2.
