Cisco Compatible eXtensions Solutions
Another WiFi device testing program comes from Cisco Systems. Their program, known as the Cisco Compatible eXtensions (CCX), involves a set of test programs that certifies the interoperability of client devices with their infrastructure products. The CCX logo is given to client devices that have successfully passed CCX certification.
Cisco has designed their testing program with four versions. Each version builds around feature compliance, which then moves the product into the next testing cycle. The working protocol is that every feature supported in one version also must be supported in each subsequent version. Here are some of the elements from each version set:
Version 1: The ability of a WiFi device to interoperate with an access point supporting multiple Service Set Identifiers (SSIDs) tied to multiple VLANs.
Version 2: Radio frequency (RF) scanning, which takes data from the access point and then is delivered to the CiscoWorks Wireless LAN Solution Engine (WLSE) for analysis.
Version 3: Support for Wi-Fi Multimedia (WMM)
Version 4: Call admission control, such as addressing voice over IP (VoIP) stability, roaming, and other Quality of Service related issues.
