Technical features:

*There is no need to set up a central station and complex system configuration. After the site is turned on and powered on, the network will be automatically connected, and the communication can be started in "seconds";

* Arbitrary topology, multi-hop relay, relay and forwarding;

* The logical attributes of each node can be flexibly configured;

* At present, the same frequency network can support the interconnection of 40 nodes;

* The channel uses AES encryption;

* The peak system data bandwidth is 90Mbps;

* Size: Length: 73mm*width 47mm*height 10mm;

* Weight: 60g

Technical advantages:

l Long transmission distance: using LDPC channel coding, space-time coding, transceiver diversity and other technologies, the receiving sensitivity can reach -98dBm, and under 2W transmission power, the ground-to-air/air-to-air line-of-sight communication can reach 30km, and the ground-to-ground line-of-sight communication can reach 10 km, it also has better anti-multipath interference and strong diffraction ability under non-line-of-sight environmental conditions, and the test bandwidth between 2km street cars and cars is up to 6Mbps data bandwidth;

l High transmission rate: adopt BPSK/QPSK/16QAM/64QAM adaptive modulation, receive diversity and other technologies, the peak rate can reach 90Mbps, which is suitable for multi-hop transmission of larger traffic;

l Large-scale network: channel resources are dynamically allocated, and the actual measurement can support 40 nodes for networking;

l Multiple relay hops: The measured video relay hops can reach 8 hops, which expands the network coverage and enhances the applicability of network applications;

l Software architecture: a centerless, distributed wireless self-organizing network based on the IP system;

l Anti-multipath interference: TDD-OFDM multi-carrier modulation has strong resistance to multipath interference;

l Diffraction ability: strong diffraction and penetrating power;

l Dynamic routing: Layer 2 intelligent routing protocol;

l Flexibility: Strong scalability, nodes can be added and exited dynamically;

l Mobility: The maximum mobile speed of the tested node is ≥160 km/h;

l Anti-destruction and self-healing: individual terminal damage will not affect the normal operation of the network, and has a strong anti-destruction ability;

l Working mode: star network, mesh network, chain network, point-to-point, point-to-multipoint, multi-point-to-multipoint;

l IP transparent transmission: support IP transparent transmission from network port to network port, network port to serial port, and serial port to serial port;

l Internet expansion: effectively extend the coverage of the Internet, any terminal in the network can be used as a gateway, and each node of the ad hoc network can access the Internet through the gateway node;

l Spectrum scanning: With the function of spectrum scanning, you can view the current spectrum usage and indicate interference;

l Configuration management: the radio channel, bandwidth, power, speed, IP, key and other parameters can be set;

l Status display: can dynamically display network topology, link quality, signal strength, environmental noise, etc.;

Performance parameters:

l Network scale: single frequency supports 40 nodes;

l Communication frequency: 1412~1452MHz, 1MHz step adjustable;

l Transmitting power: 2*30dBm (2*1W), 1dBm step adjustable;

l Bandwidth mode: 5/10/20 /40MHz;

l Modulation method: multi-carrier TDD-OFDM;

l Carrier modulation: BPSK/QPSK/16QAM/64QAM (adaptive or fixed);

l Receiving sensitivity: -98dBm @ 10MHz;

l Communication rate: peak value 90Mbps (adaptive);
