“BARS-D” reversible 5 W VHF digital NXDN repeater
Designed for high-altitude, solar-powered installation in uninterrupted digital communication systems.
The NXDN digital protocol is implemented in full. Received digital packets are decoded, error-corrected (FEC coding/decoding) and regenerated before being passed to the transmitter modulator. A powerful ARM Cortex-M4 processor pipelines receive and transmit packets simultaneously, achieving the lowest repeat delay in the industry.
Key features:
- – low power consumption, ideal for off-grid systems
- – reversible Rx/Tx, allowing chains of up to 4 repeaters covering more than 200 km
- – shorter packet decoding and forwarding delay
- – compatible with NXDN and IDAS digital radios
- – supports data and signalling, enabling SCADA data acquisition systems for hard-to-reach sites in the Pamirs
- – reliable thermally insulated, weatherproof enclosure with summer/winter climate control
– for extreme conditions of -60oC and below, it can be installed underground in a trench next to the mast and solar panels
