Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz) from fixed and mobile devices, and building personal area networks (PANs). Invented by telecom vendor Ericsson in 1994,it was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronization.

There are few things more annoying than the tiny keys or on-screen keyboards that make typing a tedious and not particularly accurate chore on smart phones and handhelds. Logitech's diNovo Mini keyboard (U.S.$129) can make every keystroke count - and it can even make watching screen more relaxing.

Pogo measures 120x72x23.5mm and weighs 227g, it doesn't use ink or toner. The special 2x3in paper has microscopic yellow, cyan and magenta crystals that are activated by the printer. The Pogo can print a 278KB image in just over a minute and had a range of 37 feet.

The Vo200 is one of the smallest and lightest handsets around. It works only with Windows XP PCs, using the laptop's Bluetooth gear to connect. As long as the laptop has a broadband connection, you're able to make and take calls.

This hands-free device is perfect for those of us who hate to read directions because it actually tells you how to use it in your choice of six languages. The package includes not only the black speakerphone, but adaptors for AC and cigarette lighter sockets. It took about a minute to connect with my phone,

Interlink's VP6600 media remote (U.S.$40) is smaller than a business card, yet can control a PowerPoint show so well that every mobile presenter should pack it - especially because it charges and travels right in your laptop's Express Card slot.

MBW-150 Classic Edition is nicely styled. At the bottom of the stylish analog time dial is a small Organic LED screen that shows who is calling or that a new text message has arrived. The device's contain five control buttons. It can control phone's music collection. It not only shows what track is playing, but the three buttons on the left side can pause, move a track or change the volume.

If there's one Bluetooth accessory that can show the potential of this wireless technology while providing lots of fun, it's Lego's Mindstorms NXT (U.S.$200). It's a bunch of motors, gears, cams and electronic parts that can be put together to create various robots that respond to programs you transmit via Bluetooth. Robot can move, make noises and even pick up a ball with its claw.

Whether you're a salesperson needing to check whether a part is in the warehouse or a shopper looking for a bargain, Baracoda's D-Fly bar code scanner ($300 in the U.S.) can help. It accurately scans bar codes on the first try, and connects with a laptop or smart phone via Bluetooth. The D-Fly can't tell you the price of an item. What it does do is retrieve an item's inventory number & you can use the data to comparison-shop on the fly.
