Method of steering smart antennas

摘要

The invention includes a method of communicating in a network of multiple nodes transmitting and receiving messages to and from each other. The method includes (a) scanning in synchronism a receive directional beam of an antenna of a first node and a receive directional beam of an antenna of a second node; (b) steering, in azimuth, a transmit directional beam of an antenna of the first node to a relative bearing of the second node; and (c) transmitting a message from the first node to the second node, when the transmit directional beam of the first node and the receive directional of the second node are substantially aligned in relative bearing to each other.
