A POINT-TO-MULTIPOINT UNIDIRECTIONAL WIRELESS COMMUNICATION APPARATUS BASED ON THE FREQUENCY HOPPING RF TECHNOLOGY

摘要

A wireless broadcasting communication device with a frequency hopping type is provided to maintain a packet format of a bluetooth standard and a frequency hopping type in a wireless communication network including one or more masters and one or more slaves per each master and simultaneously transmit the same information from each master to a plurality of the slaves. Each transmitter(3) alternately transmits an FHS(Frequency Hopping Sequence) packet and a voice/data packet according as an FHS access code is selectively inputted. Each receiver(9) receives the FHS packet transmitted from the corresponding transmitter(3) according as an FHS access code is selectively inputted, synchronizes an access code and a hopping frequency for the voice/data packet with the transmitter(3), receives the voice/data packet, and outputs the received voice/data packet.
