Guizhou Province multi-point test UAV signal coverage, ad hoc network radio multi-point test signal
1. Time: June 16 to June 18, 2023
2. Location: Weining County, Bijie City, Guizhou Province
3. Organizer: Mr. Gao of a company in Shandong
Fourth, the content of the test
Multi-point test radio signal coverage
Fifth, the test division of labor
Equipment preparation: 3 sets of Wanlan Technology ad hoc network equipment, 1 laptop, 1 6-rotor drone. Division of labor: The user is responsible for the selection of the test point of the on-site headquarters, and the Wanlan engineer is responsible for cooperating with the test. Basic system settings: Ø Frequency: 1420MHz, Ø Bandwidth: 10MHz, Ø Transmitting power: 20W, 40W, Ø Video: 1080P, Ø Other special configurations: none.
Sixth, the test process
Drone video backhaul
at different distancesAs shown in the figure above, the ANYMESH-SDR-A4 fixed station is placed at the temporary base site, and each test point uses the ANYMESH-SDR-A3 airborne station to take off, and the ANYMESH-SDR-A2 vehicle-mounted piggyback station provides control during takeoff. (The 300m flight altitude of the drone is the limit altitude).
(1) The first test point
The first test site is about 60 km away from the temporary base site. The test link diagram is as follows: when the drone flies at an altitude of 300m, the video backhaul is clear and smooth.
(1) The second test point
The second test point is 60km away from the temporary base site. The test link diagram is as follows: the
connection is established at the flight altitude of 100m, and the video backhaul of this link is clear and smooth.
(1) The third test point
The connection has not yet been established at the flight limit altitude of 300m, and the distance between the third test point and the temporary base site is 50km, and there is a high mountain in the middle and the distance is too far, so that the connection with the drone cannot be established.
(2) The fourth test point
The fourth test point is 50km away from the temporary base site. The test link diagram is as follows:
(1) The fifth test point
The fifth test point is 63 km away from the temporary base site. The test link diagram is as follows:
the link is stable when the drone is at an altitude of 100m, and the video backhaul is clear and flowing.
(1) The sixth test point
The sixth test point is 48 km away from the temporary base site. The test link diagram is as follows: the
connection is established at 140m of the drone, and the video backhaul is clear and smooth.
(1) Seventh test point
The seventh test point is 38 km from the temporary base site. The test link diagram is as follows: the video backhaul of the drone at an altitude of 50m is clear and smooth.
7. Point deployment
The center is fixed at the take-off point of the drone
8. Test conclusions
The test work of each point was successfully completed, and the conclusions are as follows: 1. The system can realize high-definition video transmission and data transmission in the case of 1-hop transmission. 2. The radius of 60km can be basically covered with the temporary base site as the center.
