Bluetooth Wireless Technology; Worldwide Operation; Radio Links - Toshiba NB500 Series User Manual

Wireless communication is often subject to local radio regulations.
Although Wireless LAN wireless networking products have been designed
for operation in the license-free 2.4GHz and 5GHz band, local radio
regulations may impose a number of limitations to the use of wireless
communication equipment.
Radio Frequency
The range of the wireless signal is related to the transmit rate of the
wireless communication. Communications at lower transmit range may
travel larger distances.
■
The range of your wireless devices can be affected when the antennas
are placed near metal surfaces and solid high-density materials.
■
Range is also impacted due to "obstacles" in the signal path of the radio
that may either absorb or reflect the radio signal.

Bluetooth wireless technology

Some computers in this series have Bluetooth wireless communication
function which eliminates the need for cables between electronic devices
such as computers, printers and mobile phones. When it is enabled,
Bluetooth provides the wireless personal area network environment which
is safe and trustworthy, that is quick and easy.
You cannot use the computer's built-in Bluetooth functions and an external
Bluetooth adaptor simultaneously. For reference, Bluetooth wireless
technology has the following features:

Worldwide operation

which is license-free and compatible with radio systems in most countries
in the world.

Radio links

links being maintained even if the devices are not within a line-of-sight of
each other.

Two advanced security mechanisms ensure a high level of security:
■
Authentication prevents access to critical data and makes it impossible
to falsify the origin of a message.
■
Encryption prevents eavesdropping and maintains link privacy.
