This paper proposes a hybrid communication system integrating low-power wireless mesh networks (LP-WMN), 5G backhaul links, and fibre optic communication to enhance the communication capabilities of remote power infrastructure.The system design includes a LoRa-mesh-based perception layer, a 5G millimetre-wave backhaul layer, and fibre fusion technology at the core layer to overcome the bandwidth bottleneck of the LoRa protocol, ensuring efficient and stable large data transmission.The proposed three-layer joint optimisation mechanism, comprising load-aware AODV routing, power adaptation algorithms, and time-slot scheduling, dynamically adjusts network paths, transmission power, and time slots, effectively improving system throughput, reducing delays, and optimising energy efficiency.Simulation and field test results demonstrate significant improvements in throughput, delay, and energy efficiency compared to traditional LP-WMN systems, with enhanced system stability and reliability.This system provides a reliable communication foundation for future IoT applications, such as smart grids.
