Executive Summary

Smart antennas are a specific type of directional antenna able to dynamically control the gain as a function of direction. This contrasts with more traditional directional antennas, where the dynamic ability is missing, and with omni-directional antennas, which are designed to have equal gain in all directions. Because of these characteristics, smart antennas may provide increased communication range by dynamically concentrating the transmitted power towards the intended receiver(s). This also reduces the contention on the wireless medium, as devices not involved in transmissions are less affected. Both features yield increased reliability at the physical level, an asset for network functionality such as routing protocols.
