Bluetooth could be dealt a serious blow as a connector of peripheral devices to PCs when a wireless Universal Serial Bus (USB) chip ships early next year from Cypress Semiconductor, writes Antony Adshead.

While Bluetooth has struggled to be incorporated into the latest operating systems, USB connectivity has been common for years. Making USB wireless with the CY694X processor means that cableless connections can be achieved with existing USB drivers which have long been built into devices, cutting out the time and expense of seeking Bluetooth software.

The Cypress Wireless USB chips will provide the processing power to connect up to seven devices at a range of up to 10m. It will give a latency of 20 milliseconds with eight devices connected, which drops to 8 milliseconds with four hooked up.

The chip will ship in production volumes in Q1 2003 and could be incorporated into hardware later in the year. Wireless USB operates in the same 2.4GHz frequency band as Bluetooth.
