Andrew von Nagy from Revolution Wi-Fi comments:
The industry needed a high performance, yet secure, solution to this mobility problem. The answer lies with fast secure roaming. Pre-standard solutions, such as CCKM and OKC have been around for some time but have failed to realize widespread adoption, especially by client manufacturers. The Wi-Fi Allianceâ„¢ Voice-Enterprise certification program, introduced May 2012 and already appearing in major WLAN products, brings a standards-based fast roaming method to market, which serves to align infrastructure and client manufacturers on a common implementation method and provides the benefits of low-latency roaming performance while maintaining strong security with WPA2-Enterprise.
Wi-Fi is hard. Doing voice over Wi-Fi is really hard. I can remember trying to figure out how to make voice calls walk down hallways without dropping. Read Andrew’s whitepaper to learn more about ways to ease your pain.
