4. Test data
(1) ANYMESH-02-2 0W Ground 1 Radio 192.168.144.190 WITH ANYMESH-02-2 0W GROUND 2Radio 192.168.144.191 is 130km apart, and the top of the mountain is 2 stations with ANYMESH-03-10W drone station 192.168.144.202 is 160km away from each other, and the drone is at an altitude of 400 meters Left and right, ground 4 radio station 192.168.144.201 placed under the roof of the drone.
As shown in the figure above, the drone realizes nearly 300km of drone video back to the Tsingshan command center through Taishan relay
(2) All radio frequencies are set to 1310/1320/1330/1410/1420/1430MHz, and the adaptive intelligent frequency selection mode is enabled. The transmit power is 20 W and 10W, respectively. Terrestrial Radio 1 and Terrestrial Radio 2 use a 10dBi gain 2 m length glass steel antenna, and the drone and terrestrial station 4 use an on-board 1 150-1400 MHz omnidirectional antenna4 roots gain 4.5dBi.
(3) ANYMESH-02-2 0W GROUND 1 RADIO 192.168.144.190 WITH ANYMESH-02-2 0W GROUND 2Radio 192.168.144.191 is 130km apart and the link quality is 12,1 5 as shown in the figure below:
(4) The link quality between each station is as follows: Tsingshan Ground 1 radio station 192.168.144.190 and Taishan Yuhuangding 2 radio 192.168.144.191 link is (10,13), Taishan Yuhuangding 2 radio station 192.168.144.191, and UAV 192.168.144.202 link is (7,7) UAV 192.168.144.202 and terrestrial 4 radio 192.168.144.201 link quality is (20,19) The figure is as follows:
(5) Screenshot of the actual packet filling rate in each working bandwidth mode:
The working bandwidth is 10Mbit/s, the packet rate is 4.64Mbps, and the working bandwidth is 5 MHz, and the packet rate is 2.83Mbps:
Test results: The 1080P video (about 2-4Mbps) of the drone pod was transmitted back to the Tsingshan command center.
The ANYMESH ad hoc network radio realizes the test application of UAV flight at 160km, and realizes the 1080P video backhaul of UAV at nearly 300km through Taishan relay.
The packet rate is 2.83Mbps at 5 Mbit/s bandwidth and 4.64Mbps at 10 Mbit/s bandwidth.
