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. Radio Frequency Interference Requirements This device is restricted to indoor use due to its operation in the 5.15 to 5.25GHz frequency range. High-power radars are allocated as primary users (i.e. priority users) of the bands 5.25 to 5.35GHz and 5.65 to 5.85GHz and that these radars could cause interference and/or damage to LE-LAN devices. 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: Security 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. Worldwide operation 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. Radio links 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. User's Manual 7-7
