Motorola plans to acquire XtremeSpectrum, the folks who own a pile of ultrawideband (UWB) patents: Read the article for an excellent summary of why UWB is powerful. Motorola and XtremeSpectrum were one standards voting bloc on the IEEE 802.15.3a task group, with Intel, Texas Instruments, and a bunch of other folks in the Multi-Band OFDM Alliance on the other side. 802.15.3a is designed to offer 100 to 480 Mbps at ranges from 10 to 30 meters for streaming media and instant peripheral attachment.
A host of proposals coalesced into these two camps, and it makes sense that Motorola wants a piece of the action, even though both they and XtremeSpectrum agreed to offer free licensing for 802.15.3a developers to sweeten their proposal.
