802.11b/Wi-Fi
Wireless LANs, or 802.11b/Wi-Fi, are local area networks
that use radio frequency technology to connect devices without cabling.
They offer more flexibility than traditional wired networks by providing
Internet and network access when and where you need it. New industry
standards and innovative technologies have made wireless LANs faster,
more secure, and more practical than ever before.
Wi-Fi wireless technology is intended to extend or replace
conventional wired networks. Transfer speeds of 11 Mbps provide
the throughput necessary to support a full, rich range of LAN services
without wires, allowing full flexibility within office and public
environments.

Bluetooth
Connective Convenience
A tiny microchip, incorporating a radio transceiver, is built into
digital devices. The Bluetooth technology makes all connections
instantly and without an inch of cable. It facilitates fast and
secure transmissions of both voice and data, even when the devices
are not within line-of-sight. The radio operates in a globally available
frequency band, ensuring compatibility worldwide.
Connecting Inner Space
The Bluetooth technology makes personal area, wireless connections
as simple as switching on the lights. All you digital devices will
communicate spontaneously. To become truly wireless is not just
a matter of connecting to the other side of the globe. It is as
much a matter of connecting to the other side of the room.
Voice/data access point
The Bluetooth technology simplifies access other networks. This
is done by recognizing and connecting to different types of networks
through a Bluetooth connection. For instance, you can just as easily
and instantly connect to the Internet via a mobile phone as via
any Bluetooth-enabled wire-bound connection.
Cable replacement
The Bluetooth technology eliminates the need for troublesome cable
attachments. You can, for instance, send and receive e-mail on your
mobile computer via your mobile phone, even when the devices are
not within line-of-sight.
Personal ad-hoc networks
All your Bluetooth-enabled devices can be set up so that when they
automaticxally exchange information and synchronise with one another.
For instance, if you accept an appointment on your handheld device,
the appointment is automatically accepted in your desktop PC as
soon as the two devices are within range of each other.
Speed and Security
The Bluetooth technology is designed to be fully functional even
in very noisy radio environments, and its voice transmissions are
audible under severe conditions. The technology provides a very
high transmission rate and all data are protected by advanced error-correction
methods, as well as encryption and authentication routines for the
user's privacy.
Future reality
The Bluetooth technology is the result of the joint achievements
of five leading companies within the telecommunication and computer
industries (Ericsson, Intel, IBM, Nokia and Toshiba). More than
2000 other manufacturers, from all parts of the world and various
fields of business, have now also joined the Bluetooth family. This
makes it by far the fastest growing industry standard ever.
Before year 2002, the Bluetooth technology will be built into hundreds
of millions of electronic devices.
