The DJ/HZ-33-100S-C self-organizing network equipment, with long-distance, low latency, and high stability transmission as its core advantages, realizes self-organizing network communication between the sky end and the ground end, breaks through the limitations of long-distance operation and no public network signal, fully adapts to various outdoor unmanned aerial vehicle high-definition image transmission scenarios, and provides a professional and reliable integrated solution for industry applications.

The equipment comes standard with a combination of one sky end and one ground end, which deeply adapts to the high-definition image transmission needs of industrial drones from hardware structure to functional algorithms, truly achieving real-time transmission and high-definition presentation of aerial images.

1、 Sky end | Lightweight integration, easy to carry, fast networking

As the core of airborne signal acquisition and transmission, the Sky Terminal adopts a lightweight integrated design, with a total weight of only 280g, small size, and low load occupation. It is suitable for various industrial drones to carry and does not affect the endurance and flight stability of the aircraft.

The device can seamlessly integrate with drone pods and onboard cameras, real-time capture high-definition images, and rely on self-organizing network technology to complete wireless high-definition video transmission. Equipped with strong anti-interference ability, it can adapt to complex electromagnetic environments in the air and ensure stable and reliable transmission links.

Support automatic networking upon startup, no need for complex debugging, can quickly establish communication with the ground end, simple on-site deployment, flexible adjustment, greatly improving operational efficiency, especially suitable for emergency rescue, on-site investigation and other work scenarios that require quick response.

2、 Ground end | No switching, easy deployment, high decoding, stable reception

The ground end serves as the core for signal reception and video decoding, with a simple design and convenient operation. Supports direct connection to computers via Ethernet ports, without the need for additional adapter devices. The deployment can be completed by simply plugging in the Ethernet cable, allowing for quick reception and real-time decoding of high-definition video signals transmitted back from the Sky end.

Built in high-performance decoding chip, compatible with multi-resolution video decoding, smoothly outputs 1080P high-definition and 4K ultra clear images, with clear picture quality without dragging or blurring, meeting multiple business needs such as precise observation, image archiving, and remote real-time command.

Equipped with real-time signal strength display function, it intuitively presents the network connection status of the sky and earth terminals, making it convenient for operators to adjust the drone's flight position in a timely manner, ensuring stable transmission links throughout the process, and avoiding signal interruptions that may affect work progress.

3、 Tested hardcore performance | Long transmission delay, low latency, strong anti-interference

Under line of sight conditions, the maximum transmission distance of the device can reach 50km; using OFDM+TDD bidirectional wireless communication technology, it has excellent anti multipath interference and anti occlusion capabilities, and can maintain link stability in complex terrain and strong electromagnetic interference environments.

The transmission delay reaches the millisecond level, and the real-time synchronization of the screen is seamless and lag free;

Support flexible allocation of multiple bandwidths:

1.4MHz

3MHz

5MHz

10MHz

20MHz

Flat system architecture design, effectively reducing system latency and improving transmission throughput; Nodes and central nodes share bandwidth unidirectionally and have concurrent uplink and downlink. With a bandwidth of 20MHz, the maximum data throughput can reach 100Mbps, combining multiple advantages such as long transmission distance, high throughput, and strong anti-interference ability.

4、 Wide range of industry adaptability across all scenarios
