ThePortable Handheld Mesh Radiois an advanced communication device incorporatingCOFDM transmission technology, designed for modern integrated cable & wireless communications. It operates across a broad frequency range from 450MHz to 1.5GHz, utilizing COFDM modulation to deliver strong anti-multipath interference performance and high-speed mobility support, with a peak data rate of 47Mbps—ideal for real-time HD video, voice, and data transmission.

This radio supports dynamic mesh networking with up to 256 nodes, intelligent routing, multi-hop relay, and anti-jamming capabilities, enabling it to establish stable networks in complex environments. It offers a wide range of interfaces, including Ethernet (aviation plug), HDMI video input, 4G/5G public network access, and BeiDou short message service (SMS), achieving seamless integration between cable & wireless communications. Additionally, it supports DES/AES/SM4 encryption and 1000 hops/sec frequency hopping for secure operations.

This mesh radio is widely used in military communications, emergency response, fire command, border patrol, and industrial IoT applications. Its compact design (155mm×65mm×32mm), IP67 rating, and wide operating temperature range (-40°C to +65°C) ensure reliable performance in extreme climates and challenging conditions. Whether for dismounted soldiers, vehicle fleets, drone cooperation, or fixed-point monitoring, it delivers efficient and dependable communication support.

As communication technology continues to evolve, COFDM systems and mesh networks have become central to integrated modern communications. This product not only enhances operational flexibility in battlefield and emergency scenarios but also serves as a key component in building integrated"air-space-ground"command systems.
