APPARATUS FOR INTERFACING FIRE PROTECTION TIME DIVISION AND METHOD FOR INTERFACING COMMUNICATION USING THE SAME

摘要

PURPOSE: A fire fighting time sharing relay device and communication relay method using the same are provided to perform wireless communication by removing communications barrier according to inter-channel reciprocity spurious. CONSTITUTION: A feedback interference removing device is embedded with an FPGA(Field Programmable Gate Array) to remote relay devices. A plurality of remote relay devices is installed in underground. A plurality of remote relays relay communication between a wireless terminal(4100) and an underground wireless terminal.
