Abstract:
1. A method for performing synchronous access between a first communication device and a second communication device in frequency hopping radio communication, which comprises the steps of: configuring the first communication device to adopt N frequency hopping channels and perform frequency hopping in a predetermined frequency hopping sequence and at a predetermined frequency hopping time interval; sending, via the first communication device, a broadcast beacon over the N frequency hopping channels with a cycle of M times the predetermined frequency hopping time interval, wherein the broadcast beacon carrying synchronization information for synchronous access of the second communication device, and M and N are both natural numbers and are relatively prime; receiving, via the second communication device, the broadcast beacon over any one frequency hopping channel of the N frequency hopping channels to acquire the synchronization information, the receiving step further comprises the steps of: exchanging further information, via the second communication device, with the first communication device for access.
