Data Sheet

The new JAVAD High Speed Radio (HSR) utilizes unique Software-defined radio (SDR) architecture running on the powerful Xilinx System-on-a-Chip ZYNQ module in the conjunction with the high performance, highly integrated RF Agile Transceiver AD9361 from Analog Devices.
The HSR utilizes Single-Input and Multiple-Output (SIMO) technique, which improves the quality and reliability of a wireless link and makes HSR especially effective in operating at multipath situations in urban and indoor environments.
The HSR provides a high-speed Point-to-Point and Point-to-Multipoint wireless data transfer at up to 7.1 Mbps. Implemented the most advanced Orthogonal frequency-division multiplexing (OFDM) modulation techniques allows achieving the highest data speed for a given range (up to 2 miles). The embedded Forward Error Correction (FEC) algorithms improve sensitivity and selectivity of the radio. Master-Slave TDD mode of the HSR allows establishing bidirectional half duplex data transmission. TDD Upload and Download channels throughput balance can be tuned very flexible to satisfy user demands. The other features of HSR include data scrambling, interleaving, user selectable transmit output power level, low power consumption turn off mode. HSR supports separate Data link and Control link (with very easy command set) over USB. The built-in software provides the wireless link setting, selecting mode of operation, units’ status and error statistics monitoring, TDD protocol configuration.
The HSR could be ideally suited for applications like video stream transmission from civilian unmanned aerial vehicle (UAV) to the ground user.
