Vendor disagreements mean that the full 802.11e standard won't be ratified until mid-2005, but the part of it that handles SVP-style prioritization has been ready since early 2004. The Wi-Fi Alliance has branded this element as Wi-Fi Multimedia Extensions (WMM, also known as WME) and began certifying products for interoperability in August. The first of these should be shipping around now, which gives network managers planning Wi-Fi telephony another dilemma: Is prioritization good enough, or should they wait for bandwidth provisioning?
The official spin is that WMM is sufficient for the relatively low data rates required by VoIP, with full 802.11e only necessary for fast "consumer" applications such as video streaming. However, this coincides suspiciously with the capabilities of existing wireless products. While most APs made in 2004 can support WMM either natively or through a firmware upgrade, they're not necessarily upgradeable to full 802.11e.
