The Wi-Fi Alliance has flipped the switch for its certification programs: New devices that want to pass the Wi-Fi certification program and use its trademarked seal must include WPA2, the version of Wi-Fi Protected Access that includes the full IEEE 802.11i security spec, such as AES-CCMP encryption keys. The alliance has never made such mandatory elements retroactive, but it's likely that products lacking WAP2 or lagging in adding it will find a competitive necessity to do so when all new products will be able to trumpet this fact. It's critical for enterprise, which demands the highest levels of available encryption and security, but not very important for homes or small offices.
