QL-MESH202-A2W20 Backpack Base Station High-Performance Self-Organizing Network Radio

Product Overview

The QL-MESH202-A2W20 backpack base station self-organizing network device is highly mobile and flexible, allowing it to be carried on the back to reduce additional weight or used as a temporary relay base station for fixed placement. Once powered on, it can automatically establish a network without additional configuration. Each backpack node does not need a central node to relay data; all nodes can simultaneously serve as data collection nodes, relay nodes, and data output nodes. The networking method dynamically changes with the environment to meet multi-scenario application needs. The device can achieve a transmission range of up to 20 km in an open line-of-sight environment and 150-200 km or more in elevated scenarios (air-to-ground line-of-sight). It can maintain high data transmission performance even in heavily obstructed environments. Designed to military-grade standards, it is effectively used in harsh environments.

This backpack base station self-organizing radio adopts an FPGA platform solution, COFDM technology, and mobile ad hoc network technology. It does not rely on any basic communication infrastructure and can establish a temporary, dynamic, and fast wireless IP MESH network. This network features self-organization, self-recovery, and high resilience, supporting multi-hop transmission of data, voice, video, and other multimedia services. It is suitable for various applications, including military forces, maritime police, public security and armed police, anti-terrorism units, border and coastal defense, firefighting and emergency response, rescue and disaster relief, oil and chemical industry, ports and water conservancy, forestry and transportation, mining tunnels, intelligent robots, unmanned vehicles and boats, field operations, temporary meetings, wireless video transmission, environmental monitoring, individual soldier networking, vehicle networking, and UAV swarm networking.
