Bluetooth

Bluetooth is a standard for wireless connection of electronic devices and peripherals. It is designed to be small and easily intergrated so that it can be used in smaller devices and consume less power. The down side of this is that its transfer rates are relatively slow compared to other wireless technologies. Bluetooth uses radio-frequency signals and does not require a 'line of sight' that its predecessor, infra-red did.

Versions

Bluetooth 1.x

Bluetooth 1.x covers all the older versions of Bluetooth. Virtually every current Bluetooth-enabled device today supports Bluetooth 1.x. Speeds range from 1 Mbps down.

Bluetooth 2.0

Bluetooth 2.0 is a recently introduced update to the bluetooth standard. It allows for datarates up to 3 times faster than the original Bluetooth standard, with the maximum theoretical being 3 Mbps. It is completely backward-compatable with Bluetooth 1.x devices.

Very few devices currently shipping sport Bluetooth 2.0, however Apple's current laptops - PowerBooks and iBooks - do.


Devices

Many different kinds of devices can be Bluetooth enabled. Generally, they fall into one of these categories:

Mobile Phones

Many of todays cell/mobile phones include bluetooth for transfers of media files (MP3's, photo's, videos) and for sychronisation purposes (Calanders, Contacts, emails) Some phone makes and models are known to have 'better' bluetooth implementation, with some including basic support for file transfers and others allowing full sychronisation through iSync. It is always worth researching before buying to avoid dissapointment. As an example, most Samsung phones do not allow for Java applications or games to be transferred via bluetooth where as Sony Ericsson have excellent bluetooth support that is usually fully complete and compatible with Apple Macs.
