Wireless USB slowly steps forward

The PC-centric version of ultrawideband took a small step forward this week, when three companies became the first to have their wireless USB (WUSB) silicon certified by the USB Implementers Forum.

Intel and NEC have host chips ready to go and Alereon and NEC have chips for peripherals. The spec can deliver wireless links with data rates up to 480 Mbit/second over three meters.

The group said full products should ship by June, at least nine months later than originally scheduled. The group finished its spec in May 2005. At the time it hoped to have chips certified by the end of 2005 and products shipping in the fall of 2006.

It's not clear whether the group has lost momentum since that time when as many as 40 companies said they were interested in building some form of WUSB chips and the group believed it would knock down all the global regulatory hurdles still in front of ultrawideband technology.

Cost and integration challenges are still ahead. To really make this market rock engineers need to get standalone chips down to $5 and even integrate WUSB into existing chip sets for systems such as digital cameras, notebook computers and media players. These issues just take time as proponents of Bluetooth, just now coming into its stride, have learned.
