Setting Wireless Properties

The wireless properties affect how the badge operates on you organization's wireless network.

Table 1. Wireless properties
Property	Description	Badge Types Supported
Wireless Band	Select the wireless bands used by the B3000n badge: ABGN—Uses all 802.11 wireless bands (a, b, g, and n) at 2.4 GHz and 5 GHz. This is the default setting. AN—Uses 802.11a and 802.11n wireless bands at 5 GHz. BGN—Uses the the 802.11b, 802.11g, and 802.11n wireless bands at 2.4 GHz. A—Uses the 802.11a wireless band at 5 GHz. BG—Uses the 802.11b and 802.11g wireless bands at 2.4 GHz.	B3000n
2.4 GHz Channels: Set to Defaults (1, 6, 11)	Select this option to force badges to scan the three non-overlapping 2.4 GHz channels of 1, 6, and 11.	B3000n, B3000, B2000
2.4 GHz Channels: Specify Channels	By default, B3000 and B2000 badges scan only channels 1, 6, and 11 unless you select the Specify Channels option. Selecting Specify Channels allows you to specify up to four arbitrary channels to scan. 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, select Specify Channels and enter the specific channel numbers in a comma-separated list. Make sure you specify only channels that are supported for your locale.	B3000n, B3000, B2000
5 GHz Channels: Set to Defaults (36, 40, 44, 48)	Select this option to force B3000n badges to scan the four 5 GHz channels of 36, 40, 44, and 48.	B3000n
5 GHz Channels: Specify Channels	By default, B3000n badges scan only channels 36, 40, 44, 48 unless you select the Specify Channels option. Selecting Specify Channels allows you to specify any number of the following channels in the 5 GHz band to scan: 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140, 149, 153, 157, 161, 165 Enter the specific channel numbers in a comma-separated list. Make sure you specify only channels that are supported for your locale. Also, make sure the 5Ghz channels available in the wireless controller match the ones defined in this property. See Wireless Channels.	B3000n
Roaming Policy	The Roaming Policy property specifies how quickly a badge searches for an access point when signal quality drops. Higher values cause a badge to search sooner, and may correct problems with choppy audio. However, a badge cannot send or receive audio packets while searching for an access point, so communication may be interrupted. Lower values allow a badge to tolerate lower signal quality before searching. The optimal threshold value varies from one 802.11 network to another, depending on how the network is configured. Select a value from 0 to 3. The default value is 2.	B3000n, B3000, B2000
CCKM	Use the CCKM field to specify whether you want to enable Cisco Certified Key Management. CCKM is a form of fast roaming supported on Cisco access points and on various routers. Using CCKM, Vocera devices can roam from one access point to another without any noticeable delay during reassociation. After a Vocera device is initially authenticated by the RADIUS authentication server, each access point on your network acts as a wireless domain service (WDS) and caches security credentials for CCKM-enabled client devices. When a Vocera device roams to a new access point, the WDS cache reduces the time it needs to reassociate. By default, this property is not selected. In order to take advantage of this feature, your access points must also support it, and you must use either LEAP, WPA-PEAP, EAP-FAST, or EAP-TLS authentication.	B3000n, B3000, B2000
802.11d	Use the 802.11d field to specify whether you want badges to select AP channels based on the country code broadcast by access points and the channels entered in the Specify Channels fields. By default, this property is not selected. In order to take advantage of this feature, your access points must also support it.	B3000n, B3000, B2000
