Patent ID: 8498250

Claim:
A method for communication between a first device having a first directional antenna and a second device having a second directional antenna, the method comprising: establishing a superframe having a superframe duration (T s ) and transmitting a beacon by the first device during each of the superframe duration (T s ); performing a sector scan by scanning all sectors (N beam ) by the second device for two scan periods (2N beam T s ) in each sector scan, the second device scanning each sector for a superframe duration (T s ) within each scan period; performing a jump sequence between channels, the jump sequence having a sequence duration (T total ) which is equal to a sum of a control duration (T c ) of a control channel and durations of data channels (KT d ); repeating the jump sequence; establishing a new superframe if no existing beacons are detected on the control channel, or joining an existing superframe on the control channel during the control duration (T c ) if existing beacons are detected on the control channel; scanning by the second device during a duration of a data channel (T d ); finding the first device by the second device during a find time (T f ); selecting a common channel to start communication with the first device over the common channel and stopping the jump sequence.
