Key Features
System list
- Point to point and point to multipoint broadband and transparent data transmission equipment.
- OFDM (Orthogonal Frequency Division Multiplexing).
- MIMO (Multi-Input & Multi-Output), SDR (Software Defined Radio) and other technologies.
- Supports multiple bandwidth allocation (1.4/3/5/10/20MHz)
- Application: UAV, robot image data transmission
- Multi-service interface: 2 Ethernet ports, 3 RS232 serial ports, 1 audio input/output port.
- Automatic frequency hopping within the frequency band, frequency band scanning to avoid interference.
- 3/5/10/20MHz wireless bandwidth, all nodes share the working bandwidth, and the maximum sharing rate of the system is 30Mbps.
- The system automatically adapts to the QPSK/QAM16/QAM64 modulation method.
- Networking mode: point-to-point, point-to-multipoint star networking, Mesh networking (customized).
- Support to specify center, child node or choose center node independently. Support sub-nodes for transit transmission through the central node.
- Multicast and broadcast. Supports up to 16 child nodes.
- Real-time detection of reception level status/antenna calibration
- Real-time scanning of site frequency bands and channel detection
- Access authentication is available to prevent illegal access. Support user-defined encryption, support AES128 encryption and decryption.
- High receiving sensitivity, up to -103 at 10MHz bandwidth.
- Device configuration and working status can be viewed through the web UI or serial port.
