Multi-Station with one Frequency Fire Emergency Network Based on TDD-OFDM

Abstract:

For the problem of presence fire district network, multi-station with one frequency fire emergency communication network based on TDD-OFDM is proposed. The network mode and the basic structure and operating principle of the receiving and sending equipment from central station, car relay stations, as well as single firefighter piggyback are introduced, as a result ,voice and video data can be high-speed transmitted, thus, the frequency utilization and bandwidth of the broadcast networks are improved.
