The design of firefighting mesh private network base station based on 5G technology
A fire mesh dedicated network communication base sta-tion based on 5G technology has been designed,which uses key technologies such as bidirectional OFDM transmission technol-ogy,carrier aggregation,wireless sensing anti-interference,and routing algorithms in mixed scenarios.Without increasing the transmission power of the base station,the network communica-tion rate is increased,the transmission distance is expanded,and the anti-interference performance is improved.Network perfor-mance testing and field application testing have been conducted in laboratory environments.The experimental results show that the maximum communication bandwidth of private network base sta-tions can reach 100 Mbps,and the point-to-point transmission distance of base stations can reach more than 80 km,effectively avoiding interference from other useless signals in the same fre-quency band.After multi hop networking,the base station still has high data transmission ability and the delay is basically the same as that of dual hop networking.This base station can serve as the core communication node of the digital battlefield,solving the problems faced by traditional Mesh equipment and technology.
