Range
802.11b is usually used in a point-to-multipoint configuration, in which an access point communicates via an
omni-directional antenna with one or more wireless stations that are located in a coverage area around the
access point. Typical indoor range is 30 m at 11 Mbps and 90 m at 1 Mbps. With (high-gain) directional
external antennas, the protocol can also be used in fixed point-to-point arrangements, typically at ranges up
to 8 km.
By using directional antennas you can enlarge the range of your network.
