General notes on using the wireless LAN functio n

In some countries, using WLAN products may be restric ted by the local regulations (e.g. limited number of channels).
Before activating the WLAN function, read the Safety Information carefully.
The IEEE 802.11a standard and the IEEE 802.11n standard are no t available on ad-hoc networks.
The 2.4 GHz band used by wireless LAN compatible devices is also used by other various devices. Althoug h technologies
to minimize interference from other devices that use the same band are employed on wireless LAN compa tible devices,
such interference may cause lower communication speed, narrower communication range, or broken wirele ss
connections.
The communication speed and range may vary depending on the following condi tions:
Distance between communication devices
Existence of obstacles between devices
Device configuration
Radio conditions
Ambient environment that includes existence of walls and materials of such walls
Software in use
Communications may be cut off depending on radio conditions.
Actual communication speed may not be as fast as the one displayed on your computer.
Deploying WLAN products compliant with different standards that use the same band o n the same wireless network may
reduce the communication speed due to radio interference. Taking this into consideration, WLAN products are designed
to reduce the communication speed to ensure communications wi th another WLAN product if it is compliant with a
different standard that uses the same band. When the communication speed i s not as fast as expected, changing the
wireless channel on the access point may increase the communication speed.
