What is Bluetooth

Bluetooth wireless technology is a short-range communications technology intended to replace the cables connecting portable and/or fixed devices while maintaining high levels of security. The key features of Bluetooth technology are robustness, low power, and low cost. The Bluetooth specification defines a uniform structure for a wide range of devices to connect and communicate with each other.

Bluetooth technology has achieved global acceptance such that any Bluetooth enabled device, almost everywhere in the world, can connect to other Bluetooth enabled devices in proximity. Bluetooth enabled electronic devices connect and communicate wirelessly through short-range, ad hoc networks known as piconets. Each device can simultaneously communicate with up to seven other devices within a single piconet. Each device can also belong to several piconets simultaneously. Piconets are established dynamically and automatically as Bluetooth enabled devices enter and leave radio proximity.

A fundamental Bluetooth wireless technology strength is the ability to simultaneously handle both data and voice transmissions. This enables users to enjoy variety of innovative solutions such as a hands-free headset for voice calls, printing and fax capabilities, and synchronizing PDA, laptop, and mobile phone applications to name a few.

Bluetooth Headsets

Jabra FreeSpeak BT250

The high volume and clarity makes it easy to forget you're even using it, while the unique, behind-the-ear design and rotating earpiece create a comfortable fit.

Logitech Mobile Bluetooth headset

Overall sound quality is good, and since you don't have to contort your arm or ear to get it on your head (it fits behind your ear), it's one of the easiest headsets to put on. Just be wary of its large size and rather geeky look.

Motorola HS8910 Bluetooth wireless headset

It's stylish and small, with a slick oval shape and a large indicator light. It folds up to an even tinier size for easy transport. An especially nice touch is the folding boom microphone, which acts as the on/off switch.

Epox BT-HS01 Bluetooth headset

Epox is smaller than most headsets, which is a bonus. It also has a bit of style that makes it look less dorky than some other models. It took us a few seconds to get it working correctly, but once we did, volume and clarity were by and large good.

Bluetooth was first developed by Ericsson, in 1999, it provides a way for different devices to communicate with each other by sending data via a secure, low-cost short-range radio frequency. Using the technology, cell phones can talk to headsets, PCs can talk to printers or keyboards, and handhelds can talk to each other without any wires. Up to seven connections can be made at one time. Bluetooth is in wireless phones, PCs, cameras, GPS devices, handhelds, and cars.
