What could be the practical use of Bluetooth? Well, it´s very much up to our imagination. But the ambition is set high, indeed; practically all computerized equipment normally found in a modern office (and home) which do not use a synchronous communications protocol could be adapted for use with Bluetooth. Check this list:
- Phones and pagers
- LAN access devices
- Notebook computers
- Desktop and handheld computers
- Fax machines
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.
News at Comdex 1999
One of the highlights at the annual Comdex show in Las Vegas in Autumn 1999 was the Bluetooth pavilion, where Motorola showed a Palm V synchronising data with a mobile phone. Using a 3Com cradle attached to the back of the Palm V, Motorola demonstrated the types of Bluetooth devices that it will eventually be selling.
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.
TDK Systems also plans to develop a Bluetooth hub, providing four Bluetooth radios to connect to a corporate network. The hub would expand the available bandwidth of Bluetooth, allowing up to four users to connect into a corporate network at a speed of
721 kb/second each.
- A Bluetooth-mouse could be used at a further distance from a monitor, and while moving about in the room.
- 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.
- A Bluetooth-keyboard could also be used to address more than one computer, in a dynamic, switchless manner.
- 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.
- 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.
- Cable-less connection to printers and faxes.
- Cable-less connection to digital cameras and video projectors.
- Cordless connection from cell phone to handsfree headset.
- Bluetooth interface to office PBX.
- Dial-up networking and automatic e-mail.
- Use cell phone as office cordless phone.
- Use of PC or PDA as handsfree phone.
- Automatic exchange of files, electronic business cards, calendars etc.
- 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....).
