1: Test purpose
On September 10th, AnyMesh-SDR-A2 radio 20 km test report 10MHz speed measurement speed
16Mbps, 20MHz speed measurement 30Mbps
1) The audio and video transmission capacity (transmission effect and bandwidth rate) of the SDR station under the 10MHz and 20MHz carrier bandwidths;
2) Test the long-distance voice intercom function of the SDR radio station (long-distance PTT hand microphone voice intercom);
2: Test environment
The distance between the two stations is 18.54km;Point A:
One end is at the observation deck of Jingzhihu Forest Park in Changping District (about 200 meters above sea level);
Point B: One end is at the window on the 13th floor of Hongfu Building, Changping District (about 30 meters above sea level);
3: Test the equipment

4: Test steps
4.1 Audio and video transmission test at 10MHz and 20MHz bandwidth:
1080P HD video at 10MHz and 20MHz bandwidth is clear, smooth and free of stuttering.
1) The equipment at point A (about 200 meters above sea level) is an AnyMesh-SDR-A2 series backpack with a tripod height of 2 meters and a 6dBi antenna, as shown in the figure:
2) The equipment at point B (about 30 meters above sea level) is also an AnyMesh-SDR-A2 series backpack table,
which is placed on the window sill, as shown in the figure:
4.2 The relevant parameters are recorded as follows: the
carrier bandwidth is set to 10MHz, and the screenshot of the single-threaded packet filling test is as follows:
* The average packet filling rate at 10MHz bandwidth is 16.4Mbps
The carrier bandwidth is set to 10MHz, and the screenshot of the multi-threaded packet filling test is as follows:
* The average multi-threaded packet filling rate is 15.8Mbps at the 10MHz bandwidth
The carrier bandwidth is set to 20MHz, and the screenshot of the single-threaded packet filling test is as follows:
* The average packet filling rate at 20MHz is set to 30.2Mbps
The screenshot of the 20MHz multi-threaded packet filling test is as follows:
* The average multi-threaded packet rate at 20MHz bandwidth is 26.5Mbps
SDR-A2 Radio Packet Test Results
| bandwidth | Average speed rate | stability |
| 10MHz | 16.4Mbps
for single thread and 15.8Mbps for multi-thread | The video effect is smooth and the filling rate is
stable |
| 20MHz | 30.2Mbps
single-threaded and 26.5 Mbps multi-threaded | The video effect is smooth and the filling rate is
stable |
Test Conclusion:
The SDR-A2 radio uses 10MHz and 20MHz bandwidth tests when transmitting a high-definition video (resolution 1080P, bitstream 4M) and a distance of 18.54km, and the video transmission effect is stable and smooth, and the filling rate is stable.
