QL-MESH102-2W Portable Backpack Radio

Product Overview

This MIMO dual-channel backpack-style broadband self-organizing network radio offers customizable transmission frequencies ranging from 300 MHz to 1.5 GHz. It utilizes the latest generation of multi-hop self-organizing network protocols and radio technology, capable of countering complex channel environments. This allows for decentralized self-organizing network broadband service transmission between mobile and fixed points such as individual soldiers, vehicles, and drones in complex scenarios.

The radio features a built-in high-capacity lithium battery and a maximum transmission power of 2x1W. It operates independently of any foundational communication infrastructure, enabling the temporary, dynamic, and rapid construction of a wireless IP network. This network possesses self-organizing, self-healing, and high-resilience capabilities, supporting multi-hop transmissions of data, voice, video, and other multimedia services. It meets the needs of users to rapidly establish dedicated networks in emergency scenarios, providing stable transmission channels for voice, messaging, and video IP data services.

When combined with individual soldier wireless self-organizing network radios, this backpack radio can perform hybrid clustering and tiered networking. The backpack radios form the backbone of long-distance communication networks, while the individual soldier radios create squad subnets, supporting multi-hop communication of video, voice, and data. Various IP devices such as smartphones, tablets, and PCs can connect to the network through the radio’s Ethernet port or WiFi AP, facilitating interconnectivity among various IP terminals. Additionally, the radio’s own battery can provide direct 12V DC power to peripherals such as cameras.Top of Form

Significant Advantages

Bottom of Form

Ø Long Transmission Distance: Utilizes OFDM and MIMO transmit/receive diversity technologies, with a receiver sensitivity of -96dBm. With dual-channel combined 2x1W transmission power, the radio can achieve air-to-air/air-to-ground line-of-sight communication up to 30km and ground-to-ground line-of-sight communication up to 5-10km. It also demonstrates good anti-multipath interference and strong diffraction capabilities in complex terrain environments.

Ø High Transmission Rate: Employs OFDM, adaptive modulation with BPSK/QPSK/16QAM/64QAM, and receive diversity technologies. The peak rate exceeds 80+Mbps, making it suitable for high-volume multi-hop transmissions.

Ø Large Network Scale: Uses the CSMA/CA protocol with dynamic channel resource allocation, supporting up to 32 nodes in a single-frequency network.

Ø High Relay Hops: In practical tests, video relay hops can reach more than 8 hops, significantly extending network coverage, enhancing the flexibility of the self-organizing network, and improving network application suitability.
