Peer-to-peer, multi-node communication test in Beijing suburbs

        On August 26, 2021, the project team of the Communication Network Security Laboratory went to the suburbs of Beijing to carry out field tests of self-developed multi-antenna broadband ad hoc network communication equipment for long-distance point-to-point communication and three-node network communication.

        The test sites are located at the top of Fengshan Mountain next to the Jinshan Temple in Haidian District, Beijing and the top of Fengshan Mountain next to the Huazhuang Community Neighborhood Committee. After arriving at the predetermined location, the testers successively carried out the business stress test in the point-to-point scenario and the three-node networking video conference test.

        The test results show that the self-developed device can communicate normally in the urban environment with ultra-long-distance and long-distance scenarios, and its communication bandwidth can support multi-channel high-definition video transmission. In the case of multi-node (three-node) networking, its communication bandwidth delay can meet the group Online video conferencing needs, video conferencing is smooth and free of lag. This test achieved the expected effect.
