D-933LA is a point-to-point and point-to-multipoint broadband and transparent data transmission device, which adopts technologies such as OFDM (orthogonal frequency division multiplexing) and SDR(Software Defined Radio) and supports multi-bandwidth allocation (3/5/10/20MHz). The flat system architecture design effectively reduces the system delay, improves the system transmission capacity, and has the characteristics of long transmission distance, large data throughput and strong anti-interference. It can be used for image data transmission of unmanned aerial vehicles and robots.
Characteristic:
- Multi-service interface: 2 Ethernet ports, 3 RS232 serial ports and 1 audio input/output port.
- Automatic frequency hopping in frequency band scanning to avoid interference
- 3/5/10/20 MHz wireless bandwidth, all nodes share the working bandwidth, and the maximum sharing rate of the system is 30Mbps
- The system automatically adapts to QPSK/QAM16/QAM64 modulation mode
- Networking mode: point-to-point and point-to-multipoint star networking
- Support to specify the center, child nodes or choose the center node independently. Support child nodes to transfer transmission through the central node
- Up to 16 child nodes can be supported
- Real-time detection of reception level status
ü Real-time scanning station frequency band and channel detection Access authentication to prevent illegal access. Support user-defined encryption and AES128 encryption and decryption。
ü High receiving sensitivity, up to -103 in 10MHz bandwidth
ü Equipment configuration and working status check through Web UI or serial port
