Test report on ad hoc network coverage and video backhaul in an agricultural machinery park in Zheji
First, the test objective
According to the on-site environment provided by the customer, the test station is carried out. Ground-to-ground communication distance, and normal backhaul of five-channel video with maximum bandwidth.
Second, the test environment
Carry out 4 km of forest area signal coverage in non-line-of-sight agriculture and forestry parks.
3. Test points
1, Figure 1 is the test No. 1 point is placed on the table at the door of the command room, 1.5 meters from the ground height, the use of the equipment is SDR-A2-4W vehicle backpack 2, Figure 2 is the test No. 2 point is installed in the (wild donkey unmanned vehicle) 1.5 meters height, the use of the equipment is SDR-A1-4W handheld station 3, Figure 2 is the test No. 3 point is installed at the height of the room shed 5 meters, and the equipment used is the SDR-A1-4W handheld station
Fourth, the test method
After the No. 1, No. 2, and No. 3 stations are fixed, the No. 1 radio station is used as the ground control end. Connect to the PC, and the PC side can dispatch the bandwidth and video of the return of Radio 2. When the data link between Radio 1 and Radio 2 starts to freeze, we enable Radio 3 as a relay to continue to implement campus coverage video and scheduling.
5. Test results
In the case of complex and serious tree occlusion, the SDR series radio can still complete the signal coverage of the whole campus and realize the normal backhaul of control and video. The maximum bandwidth is 28 Mbps, and the five-channel video backhaul
is supported to meet the acceptance criteria, and the project acceptance is successfully completed
