The Wi-Fi Alliance is expected next week to introduce a new standard: Wi-Fi Multimedia, or WMM, will be an interim standard that will be released in advance of 802.11e. WMM is expected to help with quality of service for voice over Wi-Fi or other multimedia applications. QoS will enable network administrators to give priority to voice traffic over data traffic which will improve call quality.
There has been a lot of buzz about voice over Wi-Fi but one of the big stumbling blocks is delivering QoS. Vendors are all doing it differently at this time as they wait for 802.11e. The interim standard may allow them to converge on a similar way of handling QoS, which might make customers happy to have interoperable equipment.
