Motorola-backed moves to create a compromise solution in the UltraWideBand war appear to be stillborn, since the other side of the debate, the Multiband OFDM Alliance, failed to attend the meeting.

This was based on the Common Signalling Protocol, devised by UWB start-up Pulse~Link and backed by one of the standard proposers, Motorola. The protocol will be formally presented at the next IEEE meeting later this month and is designed to provide a coexistence platform as both sides in the war push…
