25dBm 15km 30Mbps FHSS Uav Drone Data Link Transmitter with Light Weight and Compact Size
25dBm 15km 30Mbps FHSS Uav Drone Data Link Transmitter with Light Weight and Compact Size
ZKManet2421UM is a compact and portable airborne device with HD and stable image quality. It adopts the current leading OFDM modulation technology, allowing for capturing high-quality images in high-speed motion and real-time transmission over non-line-of-sight (NLOS) conditions. During transmission, encryption is applied to the images and data, supporting frequency hopping at 800MHz, 1.4GHz, and 2.4GHz, with a transmission rate of 30Mbps and a range of 5-15KM for air-to-ground transmission. It is well-suited for long-term and high-data-flow wireless transmission applications.
* The Frequency supports 800M/Hz1.4GHz/2.4GHz; supports FHSS
* Long Range up to 5~15km(LOS)
* Low latency and low power consumption
* IP transparent data transmission
* Tough aluminum metal case
Compact Size
The transmitter is compact and lightweight, with a total weight of 124g, effectively reducing the drone's payload and enhancing its wind resistance in the air.
High Reliability
The system employs advanced Orthogonal Frequency Division Multiplexing (OFDM) modulation technology, which has strong anti-interference capabilities. It also uses AES encryption technology to effectively prevent interference and eavesdropping.
Strong Usability
Quick deployment without configuration is possible, and the system operates stably and reliably with simple maintenance.
Long Transmission Distance
Utilizing the drone's flight altitude and servo antenna tracking directional antenna technology, the transmission distance can be guaranteed at 15, 30, or longer kilometers, while the system also possesses strong diffraction and penetration capabilities.
Clear Image Transmission
The system uses H.264/MPEG-2/4 compression methods, allowing transmitted video to achieve 1080P quality, clearly presenting images captured by the drone to the user.
