Introduction
Universal Workgroup Bridge Considerations
The Cisco Compatible eXtensions (CCX) program delivers advanced WLAN system level capabilities
and Cisco-specific WLAN innovations to third party Wi-Fi-enabled laptops, WLAN adapter cards,
PDAs, WI-FI phones, and application specific devices (ASDs). The 2.4 GHz WMIC provides CCX client
support. When the 2.4 GHz WMIC is configured as a universal workgroup bridge client, it does not
identify itself as a CCX client. However, it does support CCX features.
