100km Seesaw Test of Ad Hoc Network Communication Radio Station
On February 2, 2024, the long-distance wireless communication radio developed by the company carried out a 100km long-distance communication test and achieved complete success. The performance indicators of various functional machines met the design indicators.
test the venue
This test is a fixed-point test. A communication device is set up at each of the two test points. The conditions of the two test points are as follows:
- Test point 1: Yangtai Mountain; the top of Yangtai Mountain, Haidian District, Beijing, 1,270 meters above sea level, latitude 40°04'44"N, longitude 116°02'49"E
- Test point 2: Ganquan Temple; halfway up the mountain next to Ganquan Temple in Sanhe City, Hebei Province, 210 meters above sea level, latitude 40°01'45"N, longitude 117°08'33"E
The distance between the two test points is 93.6km
Device Configuration
The main purpose of the test is to verify the communication distance and data transmission bandwidth of the communication station in an airborne or missile-borne environment. The test point at Yangtai Mountain simulates airborne equipment or missile-borne equipment, and the test point at Ganquan Temple simulates ground equipment.
Test device status:
- Yangtaishan test point: The equipment is 2×10W, and the antennas are 2 5dBi antennas or 2 2dBi antennas. During the test, 2 5dBi antennas and 2 2dBi antennas are used to simulate the scene on the flying target. Some flying targets can be equipped with 5dBi antennas, while some flying targets can only be equipped with 2dBi antennas.
- Ganquan Temple test point: 2×10W equipment, 2 5dBi antennas, simulating the ground station scenario.
- Working frequency band: 1.4GHz band
test environment
The equipment test scene on Yangtai Mountain. The test equipment is set up on a tripod at a height of about 1.5 meters.
Test environment noise floor: -97dBm.
Equipment testing scene at Ganquan Temple. The test equipment is set up on a tripod at a height of about 3 meters.
Test environment noise floor: -98.5dBm.
Test Results
The test results are shown in the following table:
- Under the conditions of the Yangtaishan device (simulating airborne or missile-borne equipment) transmitting power of 2W and antenna gain of 5dBi, the receiving data bandwidth of the Ganquan Temple device (simulating ground equipment) is 17Mbps;
- Under the conditions that the Yangtaishan device (simulating airborne or missile-borne equipment) has a transmission power of 10W and an antenna gain of 2dBi, the receiving data bandwidth of the Ganquansi device (simulating ground equipment) is 17Mbps;
