Abstract
A system and method of synchronizing two end terminals using beacon synchronization in a wireless local area network are disclosed. In one embodiment, the method comprises i) communicating with a first terminal via first and second channels and communicating with a second terminal via the first and second channels, ii) transmitting a first series of beacon frames (B11, B21, B31, . . . , Bi1, . . . , and Bn1) and a second series of beacon frames (B12, B22, B32, . . . , Bi2, . . . , and Bn2) over the first and second channels, respectively, iii) obtaining beacon intervals (bi1, bi2), wherein bi1 represents the beacon interval between the ith beacon frame (Bi1) and the (i+1)th beacon frame (B(i+1)1) for the first series of beacon frames and bi2 represents the beacon interval between the ith beacon frame (Bi2) and the (i+1)th beacon frame (B(i+1)2) for the second series of beacon frames, iv) calculating the beacon interval offset value (Δbi=|bi1−bi2|) and v) 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 (Δbi) so as t…
