The handheld IP Mesh walkie-talkie is small in size and light in weight. It is equipped with a removable lithium battery and can be held by an individual soldier or carried on his back. Fast network access and automatic multi-hop relay can provide multimedia communication services such as voice group calling, video echo, and relay transmission for individual soldiers, teams, and police dogs to achieve efficient collaboration. It also supports Beidou positioning function and WiFi coverage, and can conduct various communications with smart terminals with WiFi function. The system adopts co-frequency networking and multi-hop relay, and supports any network topology such as point-to-point, point-to-multipoint, chain relay, mesh network and hybrid network topology.
Product Introduction
Product Features
Centerless networking: Nodes have equal positions and can be used as terminal nodes, relay nodes or central nodes;
Arbitrary structure networking: nodes automatically identify optimal bandwidth data routing;
Security and confidentiality: Support AES128/256 through layer-by-layer encryption such as working frequency, carrier bandwidth, scrambling code, etc.;
Anti-interference and anti-destruction: Use COFDM, MIMO, ARQ and other technologies to improve data bandwidth and anti-interference performance;
Flexible multi-node networking: Automatically calculate link routing based on channel quality, rate, bit error and other indicators for flexible networking;
All-IP network interoperability: supports transparent data transmission, interconnection and interoperability of multiple systems, and real-time interaction of multimedia services;
Front-End Collection
The front end can be connected to various video collections such as legal recorders, helmet cameras, hand microphones, DV, and drone remote controls.
Centerless Networking
Nodes with equal status can serve as terminal nodes, relay nodes or central nodes. Nodes automatically identify and select the optimal route for bandwidth data.
