QL-MESH103-2W Airborne Embedded Module

Product Overview

To meet the communication networking needs of drone swarms where payload weight is limited, Jiangsu Qianlue Information Technology Co., Ltd. has developed the QL-MESH103-2W lightweight airborne mesh self-organizing network radio. This radio is a compact, lightweight, cost-effective, long-range, high-speed MIMO mesh radio, with dimensions of 1607025mm and a total weight of approximately 260g. It features two Ethernet ports and two data serial ports.

The QL-MESH103-2W airborne self-organizing network module is a lightweight, decentralized self-organizing network module designed specifically for drone and unmanned vehicle users. The module provides dual-channel transmission power of up to 2W. It can establish a wireless IP mesh network temporarily, dynamically, and quickly, without relying on any fundamental communication infrastructure. It features self-organizing, self-recovery, and high resilience capabilities, supporting multi-hop transmission for data, video, and other multimedia services. This product is particularly suitable for military and emergency fields, including drone networking, drone relays, and drone patrolling. With software-defined radio capabilities, it is well-suited for military and firefighting applications, as well as mobile vehicles and ships, enabling uninterrupted communication between vehicles and between vehicles and individuals.

Additionally, this product can also meet the requirements for private wireless communication networks in enclosed scenarios such as mines, tunnels, and basements. It supports point-to-point or point-to-multipoint bidirectional wireless video, voice, and data transmission. It finds broad application in fields such as smart cities, individual soldier communication for military units, public security and armed police, firefighting and rescue, emergency vehicle communication, civil defense and border patrol, unmanned marine vessels, and special-purpose robots.Top of Form

Significant Advantages

Bottom of Form
