With Bluetooth-enabled devices taking off this year, (slowly, slowly), it's inevitable that more and more Bluetooth adaptors will appear on the market. We reviewed the Gigabyte GN-BTD01 (February 2003, page 44) and now the Belkin F8T001 USB Bluetooth adaptor.
A differentiator from the Gigabyte model is that the Belkin has a small pop-up aerial on the side. Bluetooth doesn't have a great range, and the quality sharply falls off the further you get from the adaptor, but the Belkin was quite solid over 50 meters or so indoors. That's probably better then you'd ever really need, and Belkin boasts connectivity at 100 meters, which is impressive.
This adaptor also comes with Widcomm's 'My Bluetooth Places' software, which integrates seamlessly into Windows Explorer. This allows you to configure your adaptor and PAN, plus sort out file and printer sharing. Again we should iterate that Bluetooth is no substitute for a network, but it's great for connecting many low-bandwidth devices.
The Belkin adaptor costs more than the Gigabyte, but it's a trade off between cost and throw distance. In the end we found the Belkin more reliable.
