Intel and other Multi-Band OFDM Alliance members have formed a SIG (special interest group): This SIG appears to be in reaction to the stall in the IEEE 802.15.3a group on Personal Area Networking in which Motorola represents the classical ultrawideband approach and the MBOA represents a newer formation that Motorola thinks is too un-UWB-like.
Bluetooth is also the product of a SIG, but the Bluetooth SIG worked with IEEE 802.15.1 to create an IEEE ratified large subset of the Bluetooth 1.2 spec that can be used by manufacturers who want BT features without using the BT name. (They have to pay reasonable and customary patent fees, of course.)
Intel will also participant in an industry group to codify wireless USB, which is a broader alternative than Bluetooth as a cable replacement technology. Wireless USB (and FireWire/IEEE 1394) are gaining interest as a generic way to use existing protocols for connectivity without being tied to a specific cable or radio medium.
