Microwave, as the access equipment between wireless devices and transmission equipments, should provide different synchronization methods for varied services during the network design and usage. Currently, the major methods of clock synchronization supported by microwave are GPS, BITS, 1588v2, Sync. E, and TDM synchronization. The mentioned methods can meet the requirements of clock synchronization and transmission of wireless devices and transmission equipments. In order to deepen the understanding of clock synchronization, several commonly synchronization methods are briefly introduced in this section.
