发明名称 WIRELESS COMMUNICATION SYSTEM
摘要 <p><P>PROBLEM TO BE SOLVED: To provide a wireless communication system establishing synchronization of 5ms between systems at low costs by effectively using assets of the present PHS system in the wireless communication system in which a plurality of PHS systems are connected with one another via a LAN. <P>SOLUTION: The wireless communication system is constituted so that, from a first PHS controller 1-1 which generates a reference clock, other PHS controllers are sequentially connected by a master and slaves, the first PHS controller generates and outputs a clock of 8 kHz and timing of 5ms synchronized with 8 kHz, and other PHS controllers receive clocks and timing output from a host device, generate clocks of 8 kHz by being synchronized with the clocks and the timing, generate the timing of 5ms synchronized with 8 kHz based on the received timing, supply the timing to base stations connected to the PHS controllers, and when subordinate devices are connected, output the generated clocks and timing from a master port. <P>COPYRIGHT: (C)2009,JPO&INPIT</p>
