The master base station generates a second synchronization signal. The second synchronization signal is used to transfer information over a transmission medium between the master base station and the remote base station. The master base station generates the first synchronization signal from the second synchronization signal. Information is transferred over the transmission medium between the master base station and the remote base station using the second synchronization signal. The remote base station generates the first synchronization signal from the second synchronization signal. The first synchronization signal is utilized by the master base station and the remote base station for digital cordless communication. | InventorsAssigneeApplicationNo. 312778 filed on 05/17/1999US Classes:370/350, Synchronization370/503, Synchronizing375/362Frequency or phase control using synchronizing signalField of Search370/324, Synchronization370/328, Having a plurality of contiguous regions served by respective fixed stations370/350, Synchronization370/503, Synchronizing370/509, Using synchronization information contained in a frame370/513, Plural synchronization words375/354, SYNCHRONIZERS375/356, Network synchronizing more than two stations375/357, Synchronization failure prevention375/359, Self-synchronizing signal (self-clocking codes, etc.)375/362, Frequency or phase control using synchronizing signal455/450, Channel allocation455/451, Hybrid allocation455/502, Synchronized stations455/509, Channel allocation331/46, PLURAL OSCILLATORS331/49, Selectively connected to common output or oscillator substitution331/55Synchronized, triggered or pulsedExaminersPrimary: Hsu, Alpus H.Attorney, Agent or FirmUS Patent References5426633, System for processing synchronization signals with phase synchronization in a mobile communication networkIssued on: 06/20/1995 Inventor: Tanaka, et al.5627832, System for processing synchronization signals with phase synchronization in a mobile communication network Issued on: 05/06/1997 Inventor: Tanaka, et al.5636219System for processing synchronization signals with phase synchronization in mobile communication network Issued on: 06/03/1997 Inventor: Tanaka, et al.
