Question: Does Vocera support the 4-channel plan
Product and Software: This article applies to all Aruba controllers and ArubaOS versions.
The old Vocera badges scan either channel 1, 6, 11 or scan all channels. If the Aruba controller/AP is configured with the 4-channel plan, the Vocera will work. However, it may be slower roaming in some circumstances.
According to Vocera (http://www.vocera.com/downloads/ConfigGuide.pdf), the newer Vocera B2000 with software version 4.0 can selectively scan channels bases on configuration:
Channels to scan
By default, the B2000 badge scans only channels 1, 6, and 11 unless the ChannelsToScan property is set. Setting this property allows the B2000 badge to scan up to four arbitrary channels.
For optimal performance of the badge and other wireless clients, Vocera recommends that the access points on your network are set only to the three non-overlapping channels of 1, 6, and 11.
If the access points on your network are set either to four channels, to three channels other than 1, 6, and 11, or to fewer than three channels, check Specify Channels and enter the specific channel numbers in a comma-separated list.
The Channels to scan setting is available for B2000 badges only.
