I see some motherboards with the Bluetooth technology. Who can say some words about this technology?. Seems like a good tech.

Bluetooth – what’s it all about?
Connect without cables
Bluetooth is a simple instant radio solution that allows different devices to talk to each other. This means that many of the operations you do now using cables or infrared can be replaced by Bluetooth. However, because each Bluetooth device is a radio, it means that they are not limited to line of sight, and they can even communicate through walls. Also, because it doesn’t use physical cables you don’t have to worry about having the correct cable or connector for the other end of the connection.

Bluetooth is designed to transmit over 10m+ distances, but with a low power drain, which means it can be used in battery powered products (e.g. mobile phones / PDAs). ‘Personal Area Networking’ aptly describes Bluetooth’s best feature – being able to create a mini personal network with any devices within your 10m+ radio ‘bubble’.

For devices to communicate using Bluetooth they each need a radio. Many products are now available with Bluetooth built in (e.g. mobile phones from Nokia and Ericsson / printers from Hewlett Packard / Epson). However, if you don’t already have Bluetooth built in to your device you can use an add-on Bluetooth radio (e.g. computer and PDA products from Brain Boxes / printer adaptor from Hewlett Packard).

Some of the devices currently available in the market include:

- Bluetooth PCMCIA cards

- Bluetooth USB adaptors

- Bluetooth CompactFlash cards

- Bluetooth Printers and printer adaptors

- Bluetooth Network access points

- Bluetooth Mobile Phones

More devices are appearing on a regular basis from different companies.

What can I use it for?
Bluetooth applications
•In the office
Bluetooth allows you to move around at your ease, whilst keeping connections, allowing greater freedom and convenience in the office.

• Internet access
• Email
• Occasional Network access
• Exchanging files
• Synchronizing contact and calendar information between PDA / laptop / mobile phone

•In the home
Bluetooth allows you to move around at your ease, whilst keeping connections, allowing greater freedom and convenience at home.

• Internet access from different rooms
• Shared Internet access by several computers

• Synchronizing contact and calendar information between PDA / laptop / mobile phone

• Printing
•On the move
• Internet access – via mobile - GPRS
• Dialling the office to pick up emails & files

• Printing at customer’s office
• Exchanging files & e-business cards with customers / contacts
• Internet access – via public network points (e.g. airport / station)
Synchronizing contact and calendar information between PDA / laptop / mobile phone

etc....etc..........
There is a lot of resources on the web with even more detail of the specifics of the signalling used.

Bluetooth is 720Kbps. Much slower than wireless ethernet, but I expect it to improve dramatically over time. (Hey, what did modem speeds start out at, and look how high they can go now?)

As for security... Here's an article on it:

Essentially it has some issues that should be resolved before it can be considered reasonably secure.
