IV. Actual Measurement and Testing Method
Ten DJHW/HZ-27-100M-C devices were deployed at the Xingang Village site, each connected to one of the ten Hikvision cameras.
Bai'an Village deployed a device of the same model, which connects to a computer for real-time video preview and equipment management.
The contract was issued via the computer system in Xingang Village and received at Bai'an Village, with actual testing conducted to measure the long-distance data transmission rate.
The video smoothness and throughput rates of multi-node networking and point-to-point networking were tested at bandwidths of 20 MHz and 10 MHz, respectively.
V. Actual Core Data Results 1. Test performance of the 20 MHz bandwidth
The device's SNR signal level remains consistently stable at around 14, indicating excellent link quality.
The network topology reliably maintains connectivity among 11 nodes, with a measured communication distance of 17.3 km.
11-channel video streams simultaneously with smooth playback, no lag or screen artifacts.
11. Node networking: Average packet transmission rate of 31 Mbps;
Two-node peer-to-peer networking: average packet throughput rate of 54 Mbps.
2. Test performance with a 10 MHz bandwidth
It also supports 11-channel video synchronization transmission, ensuring stable and smooth video playback.
11. Node networking: Average packet transmission rate of 17 Mbps;
Two-node peer-to-peer networking: average packet throughput rate of 33 Mbps.
VI. Test Summary and Conclusion
The DJHW/HZ-27-100M-C maintains stable networking performance and excellent signal quality over long distances (up to 17.5 km), capable of simultaneously supporting real-time transmission of 10 high-definition video streams.
With a 20 MHz bandwidth, multi-node networking achieves a throughput of up to 31 Mbps, fully meeting the requirements for large-scale simultaneous multi-point networking and video backhaul services.
The peer-to-peer mode offers a bandwidth of 20 MHz with a rate of up to 54 Mbps, providing ample performance margin to support future long-distance transmission scalability.
The device supports multi-bandwidth adaptive networking and self-healing capabilities in multi-node ad hoc networks, making it ideal for various industrial applications such as field security deployment, drone-based real-time image transmission, long-distance inspection in mountainous or coastal areas, and multi-point cluster networking.
