OutField test

Qinghai Dachaidan open-air integration scale network test

        At the end of September 2021, the project team of the Communication Network Security Laboratory went to Dachaidan area of Qinghai Province to carry out field tests of long-distance air-to-ground communication and air-ground integrated multi-node networking communication of ad hoc network communication equipment for nearly a week.

        The testers mounted the self-organized network communication equipment in the airship pod to carry out the air-ground pull distance test. The test results showed that the self-developed equipment could still maintain stable communication in the case of ultra-long distance, and still ensure smooth voice service transmission under extreme conditions.

        In the air-ground integration multi-node networking test, the self-developed equipment was mounted on the airship pod and multiple UAVs, and formed an air-ground multi-node dynamic network together with the ground vehicle equipment and fixed node equipment. All fixed nodes could watch the real-time return images of the airship and UAV cameras in real time.

 The experimental results showed that in the large-scale and long-distance communication scenario, the self-developed multi-antenna broadband ad hoc network communication equipment could ensure reliable networking and stable communication between nodes.
