Time-division synchronous wireless modem device
Abstract:
A time-division synchronous wireless modem device that includes: a modem unit which transmits and receives the communication packet; a communication state judging unit which obtains a transmission cycle period and a vacant communication slot from information contained in the header of the received communication packet; and a transmission timing controller. The controller selectively determines an arbitrary one of the communication slots in a next transmission cycle period when the communication packet is not received during the entire span of the one transmission cycle period, or selectively determines the one of the communication slots to be used by estimating a vacant one of the communication slots in the next transmission cycle period from the header of the communication packets when the communication packet is received.
