HR series radios are dual-channel 2-transmitter and 2-transmitter high-performance mesh self-interlinked radios developed based on the software radio (SDR: Software Define Radio) platform. Figure 1 is the first HR02-2T2R-1400-33 mesh self-interlinked radio station. It has excellent features such as large network scale, long communication distance, stable transmission rate, wide frequency band range, strong anti-multipath interference capability, fast access/retreatment, fast routing switching speed, high-speed mobile nodes, secure communication confidentiality, and support for IP voice conferences. Before its official launch, it has been used in emergency firefighting, helicopters, drones/vehicles, marine ships and other occasions. The use effect is very good and has received good reviews from customers. Typical practical application test data include: 100km air-to-air line-of-view transmission rate 8Mbps, 26km sea ship network transmission 1Mbps video, 35km air-to-ground line-of-view transmission rate 25Mbps, 13.6km field-to-ground relatively empty transmission 1Mbps video, 5km urban road-to-ground transmission rate 5.2Mbps, and 1Mbps video transmission in 1.8km urban non-visit complex environments.
Figure 1 HR02-2T2R-2400-33 High-performance mesh self-networking station
HR series high-quality mesh self-networking station consists of a core board, power amplifier, power board, and optional HDMI/SDI/CVBS video encoding board, 4G module, GPS and other modules. Figure 2 is the core motherboard, which mainly completes the functions of baseband, MAC protocol, routing protocol, IP data transmission, serial data transmission, configuration management, etc. Currently, the core motherboard size of the product has specifications such as 55*85/60*80/65*85mm, which is very suitable for OEM integrated use. Figure 3 is an adapted 2W power amplifier, which mainly completes the amplification of transmit and receive signals, as well as controlled transmission and reception switching and other functions. Figure 4 is an adapted power board, which is mainly responsible for powering the core board, power amplifier, and other optional modules. It inputs 26~36V and outputs 24V, 3 channels 12V, and 2 channels 5V. The currently released version only includes three basic modules: core board, power amplifier, and power supply board. HDMI/SDI/CVBS video encoding board, 4G module, GPS and other modules are integrated internally or externally according to actual needs.
