FindLOS tells you, before anyone climbs a roof, whether two places can see each other.

Nav Wireless Technologies Pvt. Ltd. is an Indian company that builds optical wireless links: data carried on light instead of radio, for smart cities, defence, healthcare, education and industry. It works with universities, public bodies and private companies, and develops its products in India.

An optical link only works when nothing solid stands between its two ends. Checking that used to mean reading terrain maps by hand, link by link. FindLOS does it from the ground's height along the path, the rise of the ground from the Earth's round shape, and a clearance margin for trees, new buildings and survey error — the same way for every link.

• LOS Analysis

  Place two sites, give their mounting heights, and see whether the ground stays below the straight beam with your clearance margin to spare.

• Bulk Analysis

  Check many site pairs from one Google Earth file and download the results.

• Link Studio

  Watch how an OpticSpectra link would behave at those two sites in different weather.

• Alignment

  On site, point each device at the far end with a compass bearing and tilt.

• Fiber Planning

  Estimate a road route for fiber between two points, to compare with a wireless link.

It was built for the Nav Wireless team first. Accounts are approved by hand; a clear answer is a reason to visit the site, not a replacement for checking it in person.
