As expected, the IEEE 802.15.3a group has voted to disband: They've asked the leadership of the IEEE to withdraw the project authorization request that launched the exploration of high-throughput, short-range personal area networking. Ultrawideband (UWB) quickly became the dominant standard under consideration, and a couple dozen proposals coalesced into two.
The WiMedia Alliance and Freescale's UWB Forum will continue their separate ways in the market. Despite Freescale bringing commercial products to market through their manufacturing partners, I am still bearish on their long-term potential given that almost every other player in the industry has chosen the WiMedia approach if they've taken sides.
This means that manufacturers who want to have multiple chip vendor options for a UWB product that will support full interoperability can only go to WiMedia members. Those willing to accept a single vendor solution that has no interoperability with any other chipsets (at this point) will choose Freescale.
