Virtually any digital device can be part of the Bluetooth system. Bluetooth radio technology can also provide a universal bridge to existing data networks, a peripheral interface, and a mechanism to form small ad hoc groupings of connected devices, away from fixed network infrastructures. The dynamic connectivity-nature of Bluetooth makes it possible for this system to replace USB, and it is an improvement on Plug-and-Play-systems, where the operating system has to be rebooted for the installation to take effect. A Bluetooth-mouse is already in existence; it was shown at CeBIT in Hannover in February 2000, and more items are on their way.

The cradle contained Bluetooth radio for transmitting and receiving data and a prototype phone contained a built-in Wap (wireless application protocol) browser for viewing Web pages. It also used Bluetooth for synchronising data such as an address book.

Ericsson showed a wireless hands-free headset for its mobile phone. The headset used Bluetooth to connect to a special adapter attached to the cell phone.

Peripherals manufacturer TDK Systems showed three Bluetooth radio systems: one based on CardBus technology and designed for laptops; the second, a Compactflash card, was designed to be plugged into a handheld PC. The third was an external Bluetooth radio which could be attached to a PC via a USB cable.

1. A Bluetooth-mouse could be used at a further distance from a monitor, and while moving about in the room.

2. A Bluetooth-keyboard could be used further away from the monitor. This would reduce eye-strain for persons who are long-sighted. Increasing the distance would also reduce exposure to electromagnetic radiation from the monitor.

3. A Bluetooth-keyboard could also be used to address more than one computer, in a dynamic, switchless manner.

4. Use e-mail while your portable PC is still in the briefcase! When your portable PC receives an e-mail, you'll get an alert on your mobile phone. You can also browse all incoming e-mails and read those you select in the mobile phone's display.

5. A travelling businessman could ask his laptop computer to locate a suitable printer as soon as he enters a hotel lobby, and send a printout to that printer when it has been found, and replied in a positive manner.

6. Cable-less connection to printers and faxes.

7. Cable-less connection to digital cameras and video projectors.

8. Cordless connection from cell phone to handsfree headset.

9. Bluetooth interface to office PBX.

10. Dial-up networking and automatic e-mail.

11. Use cell phone as office cordless phone.

12. Use of PC or PDA as handsfree phone.

13. Automatic exchange of files, electronic business cards, calendars etc.

14. Dancing couples at a dance hall could receive the music through their headsets and pick the dance of their choice
    (a bit far-fetched, perhaps, but who knows? Some day....).
