1. Test Requirements
To test the transmission performance of audio and video from the front-end equipment to the forward command post via the MESH network (including UAV-mounted repeater). The main test items include:
1. Video streaming from the front-end camera to the forward command post;
2. Pull-stream bandwidth from the high-power front-end base station to the forward command post.

3. Test
3.1 Overview
To test the transmission performance of audio and video from the front-end equipment to the forward command post via the MESH network (including airborne repeater).
3.2 Test Methodology & Environment
Test Method:
One MANET9401 was mounted on a UAV at Point B (Yingrenshi Park).
One MANET9601 was installed at Point A, near the Dayan Mountain Tunnel, and another MANET9201 was installed at Point C on Baoshi Road, connected to a laptop for testing the data stream from Point C to Point A.
Additionally, two front-end MANET9101 equipped with a camera were moved in the direction of the Dayan Mountain Tunnel to test the video return performance over an extended range.
Test Environment:
Air-to-ground and urban environments.
3.3 Radio Configurations
MANET9201
Frequency: 1.4GHz
Bandwidth: 20MHz
Transmit Power: 20W
MANET9601
Frequency: 1.4GHz
Bandwidth: 20MHz
Transmit Power: 20W
MANET9101:
Frequency: 1.4GHz
Bandwidth: 20MHz
Transmit Power: 4W
MANET9401:
Frequency: 1.4GHz
Bandwidth: 20MHz
Transmit Power: 4W
4. Test Procedure
The test locations are as follows:
At Point C, a laptop and a MANET9201 high-power base station were deployed. At Point B (Yingrenshi Park), a UAV equipped with a MANET9401 airborne radio acted as a relay. At Point A, another laptop and MANET9601 commander station were set up, with two MANET9101 manpack radios and cameras placed further ahead of Point A. The test involved measuring the pull-stream bandwidth from Point C to Point A, while video from the PTZ camera positioned ahead of Point C was returned to the commander station at Point A.
5. Test Details
The devices are configured to operate at 1400 MHz with a 20 MHz bandwidth.
1. To test the pull-stream bandwidth from the high-power base station MANET9201 at Point C to Point A via the airborne relay MANET9401 at Point B.
The transmission from Point C to Point A passes through the relay at Point B, covering a distance of 9.5 km between A and C, with a tested bandwidth of around 20 Mbps.
2. To test the video return performance from the front-end camera to Point A.
The video stream returns from the front end performs well at point A, with clear, stable, and smooth imagery.
6. Test Conclusion:
In an urban environment, over a distance of approximately 9.5 km between two points, the audio and video collected by the front-end equipment can be stably relayed back to the remote.
