Patent ID: 7978659

Claim:
A method of communication in a wireless personal area network (WPAN) comprising: operating an antenna training process to discover first and second communication paths between at least two stations wherein the first communication path is a direct communication path between the at least two stations and the second communication path is an indirect path between the at least two stations; ranking, according to a quality criterion, transmitting and receiving modes; reporting to the at least two stations a best transmitting mode and a best receiving mode for transmitting and receiving signals over said first and second communication paths; establishing a mmWave communication link between the at least two stations on a selected communication path which is selected from the first and second communication paths based on the quality of said transmitting mode and said receiving mode; and switching the established mmWave communication link from the selected communication path to an unselected communication path when the mmWave communication link of the selected communication path is broken or disrupted.
