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. 

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.

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:

The Bluetooth radio transmitter and receiver operate in the 2.4GHz band, 

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

in the world.

You can easily establish links between two or more devices, with these 

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.

■

Band 5GHz (5150-5850 MHz) (Revision a and 

n)

■

Band 2.4GHz (2400-2483.5 MHz) (Revision b/g 

and n)
