摘要：A method performs synchronous access between a first communication device and a second communication device. The first communication device adopts N frequency hopping channels and performs frequency hopping in a predetermined frequency hopping sequence and at a predetermined frequency hopping time interval. The first communication device sends a broadcast beacon over the N frequency hopping channels with a cycle of M times the predetermined frequency hopping time interval. The
broadcast beacon carries general information including synchronization information. M and N are both natural numbers. The second communication device receives the
broadcast beacon over any one frequency hopping channel of the N frequency hopping
channels to acquire the synchronization information. The second communication device exchanges information with the first communication device for access. This flexible, simple and easy-to-implement synchronous access solution achieves high-efficiency utilization and good anti-interference of a bandwidth, and allows rapid and reliable synchronization with low power consumption.
