1. Test time: 2020.1.7
2Test location: Basement of 3D Building, Torch Avenue
3.Test equipment: AnyMesh-SDR-2W car radio ×3;AnyMesh-SDR-4W×1
4Test environment: The equipment is located in the Torch Avenue and the underground parking lot, with more greenery around, the underground parking lot is far away from the Torch Avenue and cannot be seen, and there are many columns and walls in the parking lot, and there are cars coming and going.
5.Test item: Simulate fire rescue and test the video and voice transmission quality between the vehicle-mounted base station and each individual node.
6.Test target: full-duplex voice real-time communication;1-channel video real-time backhaul (1Mbps bitstream) to detect the diffraction capability and transparent transmission capability of the radio station in complex environments.
7.Test Method:Radio No. 1 is placed next to the 3D Building on Torch Avenue, about 30 meters away from the entrance of the underpass and is not visible; Radio No. 2 is placed at the critical point of radio station No. 1 after entering the basement; radio station No. 3 is placed at the critical point of radio station No. 2 induction, and finally the test effect is determined by the quality of data transmission.
8.Test conclusion: This test uses a total of four radio stations, with a basement area of 35,000 square meters, after using the No. 3 radio station, the video is jammed under the remote wall block of the basement, and the fourth radio station is enabled to achieve excellent signal quality in the whole basement after four hops, and there is no jamming in video and voice.

9.Suggested measures: In order to achieve better results and meet the needs of customers, it is necessary to improve from three aspects, one is to increase the transmission power of the radio, the second is to customize the high-gain antenna, the third is to increase the antenna height, and the fourth is to use the camera with video coding as H.265.
