Patent ID: 7388857

Claim:
A method of synchronizing two end terminals in a wireless local area network, the method comprising: communicating with a first terminal via first and second channels and communicating with a second terminal via the first and second channels; transmitting a first series of beacon frames (B 11 , B 21 , B 31 , . . . , B i1 , . . . , and B n1 ) and a second series of beacon frames (B 12 , B 22 , B 32 , . . . , B i2 , . . . , and B n2 ) over the first and second channels, respectively; obtaining beacon intervals (b i1 , b i2 ), wherein b i1 represents the beacon interval between the i th beacon frame (B i1 ) and the (i+1) th beacon frame (B (i+1)1 ) for the first series of beacon frames and b i2 represents the beacon interval between the i th beacon frame (B i2 ) and the (i+1) th beacon frame (B (i+1)2 ) for the second series of beacon frames; calculating the beacon interval offset value (Δb i =|b i 1−b i 2|); and setting the interval between the beacon frames (B (i+1)1 and (B (i+2)1 ) in the first channel, and the interval between the beacon frames (B (i+1)2 and (B (i+2)2 ) in the second channel, based on the calculated offset value (Δb i ) so as to perform beacon synchronization.
