TV White Space (TVWS) Backhaul

TVWS Backhaul Data Terminal for Extended Ranges

  • Outdoor software-defined wireless terminal for PMP and PTP applications
  • Reliable fast transport of M2M, data, HD video and voice traffic
  • Very low latency supports time-sensitive applications
  • Low power requirement suitable for solar applications
  • Geo-location using built-in GPS

NuRAN’s TVWS backhaul provides an interesting alternative to traditional microwave and satellite backhaul technologies. Operating in the unoccupied television channels and guard bands, it benefits from the excellent propagation charateristics of the UHF spectrum, and can establish reliable long-range (up to 100 km), high throughput links. The lower frequencies of TV WhiteSpace perform very well in non-line-of-sight (NLOS) scenarios where trees, hills, or constructions partially block the transmission path.

The BH2 and BH3 TVWS backhaul may be used as point-to-point (PTP) terminals to establish dedicated links. The same terminals may be used in conjunction with a BH1 for a point-to-multipoint (PMP) configuration, connecting multiple terminals to a central hub.
