What is the range of the signal and will walls affect the wireless LAN?
802.11b wireless networking has a range of about 300 meters in a large open space, and about 100 meters in a typical indoor office environment. Transmission speeds decrease as the distance between the portable workstation and the access point increases. The range greatly depends on line of sight between the workstation and access point. As for walls, wireless LANs use radio frequencies for communication. So unlike infrared signals, which require an unobstructed line of sight between the remote unit and the base station, radio frequencies can pass through solid objects such as walls.
