FindLOS v1.0, Nav Wireless Technologies Pvt. Ltd.
Learn & Help
One place for guides, how-tos and answers. Each FindLOS product is explained end to end — what it is, when to use it, how it works, the steps, and the mistakes to avoid — followed by a searchable FAQ.
Single point-to-point line-of-sight feasibility
Analysis is the core of FindLOS: place two sites, give them realistic heights, and find out whether a clear optical (FSO) path exists between them before anyone drives to site.
FindLOS samples bare-earth elevation along the straight path between your sites, overlays the beam (lifted by your mounting heights and lowered by Earth curvature), and adds your clearance margin around it as a Fresnel safety gap. If the terrain stays below that envelope the whole way, the link passes.
Screen hundreds of links in one pass
Bulk Analysis runs line-of-sight feasibility across many site pairs at once, so you can screen a whole list of candidate routes before planning any field work.
You provide a set of sites; FindLOS runs the same cached LOS engine used by single-link Analysis across every requested pair, then returns each result side by side so the feasible routes stand out.
Plan a whole network topology upfront
The Multi-Link Planner is a true upfront planning surface: place all of your candidate sites first, then evaluate every possible link between them together so you can choose the network topology before committing to any single link.
You drop numbered sites on the map. On Finish, the planner evaluates every pairwise link through the LOS engine, draws each one coloured by feasibility (green clear, red blocked), and reports a per-link breakdown — distance and verdict for every candidate edge, feasible ones first.
Connect two points when a single hop is blocked
A relay is an intermediate point that breaks one blocked path into two clear hops (A → Relay → B). FindLOS surfaces the feasible regions where a relay could sit and lets an operator place it where it is practical.
Relay is device-aware contextual remediation: after a hop fails, FindLOS computes the regions where a relay would let both hops pass, highlights them, and lets you place the relay on real infrastructure. It is operator-guided placement, not a blind auto-drop.
Manual checkpoints for buildings and trees
Urban Survey lets you add manual checkpoints — buildings, billboards, trees — along the path with their estimated heights, so obstructions that elevation data does not know about are checked against the beam.
You enter a checkpoint location and estimated height along the link. FindLOS compares that height with the LOS profile at that point and marks the checkpoint PASS or FAIL, because terrain APIs do not reliably model every building or temporary obstruction.
Compare a fiber run against a wireless link
Fiber Planning estimates the trench distance, routing and cost of a fiber run between two points and weighs it against an optical-wireless link on the same path.
You set the two endpoints; FindLOS estimates the routing distance for a trenched run and applies cost assumptions, then presents it next to the equivalent optical-wireless option so the trade-off is explicit.
Aim a real device in the field
Alignment guides technicians to physically aim FSO or optical devices at each end of a link, using azimuth and tilt targets and live feedback as the device converges on the far end.
Alignment computes the azimuth (compass bearing) and tilt from each site to the other, then uses the device or phone orientation to show how far you are from the target. Local and Remote technicians work each end, and a Master coordinator can create the session, share join links and watch both sides converge.
Standalone field and engineering utilities
Engineers Tools is a set of standalone utilities — compass and bearing, coordinate conversion, weather and solar interference checks, ground elevation, the 3D globe and map screenshot — each usable on its own without running a full analysis.
Each tool runs independently on the workspace map (or its own surface, like the 3D globe). They share the same map and data engine as Analysis but do not require sites, heights or a feasibility run to be useful.
Turn an analysis into a deliverable
Reports turn an analysis into a professional deliverable — a PDF to send or an editable Word document for survey handover — with branding, letterhead, watermark and sections configured centrally so every export is consistent.
Reports are generated from the same analysis data, so PDF and Word stay consistent. Branding, letterhead, watermark and which sections appear are resolved from central admin settings at export time.
Saved locations you reuse across analyses
A Place is a saved location you reuse across analyses — an office, tower or customer site — so you do not re-enter it every time. A site, by contrast, is one endpoint of the specific link you are analysing right now.
Places live in your library independently of any single analysis. They appear in the Places panel, can be grouped, and can be used as a site endpoint whenever you start a new link.
PDF, Word and KMZ outputs
Exports are the formats you take an analysis out in: a PDF for sharing, an editable Word document for handover, and a KMZ to open the sites, link path and relay geometry in Google Earth.
Each export is generated from the same underlying analysis. PDF and Word are written reports; KMZ is the geographic companion, carrying the sites, link path and relay geometry into any tool that reads Google Earth files.

What FindLOS checks and what the results mean.
Line-of-sight means two points can “see” each other in a straight line with nothing solid in between. Optical (FSO) links carry data on that straight beam, so if terrain, a building or trees block the path, the link will not work. FindLOS checks that clear path before you send anyone to site.
PASS means the path is clear enough — the terrain stays below the beam with your chosen safety margin, so the route is worth surveying. FAIL means something rises into the path; the report shows exactly where and by how much so you can raise a tower, move a site or pick a relay.
Around the straight beam there is an oval “Fresnel zone” that also needs to stay clear, or the signal weakens even when you can technically see across. The clearance setting adds a safety margin (default 10 m) to absorb trees, growth and Fresnel effects. Increase it for risky or long routes.
Over long distances the Earth curves away beneath the beam, effectively lifting the terrain in the middle of the path. FindLOS accounts for this so a long link is not wrongly marked feasible. It matters most beyond a few kilometres.
Placing points, entering heights and managing your map.
Search for an address or click directly on the map to drop each site. FindLOS draws the link between them and prepares the terrain profile automatically. You can drag a site to fine-tune its position or type exact coordinates.
Yes. Each site accepts latitude and longitude directly, so you can paste survey coordinates for precise placement instead of relying on the map click.
Enter the height of the structure plus where the device sits on it. For an urban rooftop, add the building terrace height and the mast/mounting height — a 10-floor building is roughly 30 m. Height is often the difference between FAIL and PASS.
A Place is a saved location you reuse across analyses — an office, tower or customer site — so you do not re-enter it every time. A site is one endpoint of the specific link you are analysing right now.
How the terrain profile and blockages are calculated.
It is the side-on cross-section of the ground between your two sites, drawn from elevation data. The straight beam is overlaid on it, so you can see at a glance whether the land rises into the path.
FindLOS uses global elevation datasets to model the bare-earth terrain along the path. This is excellent for hills and valleys; for trees and buildings, add clearance margin and confirm on site.
A small rise, a single ridge or the Earth’s curvature can intrude into the beam even on seemingly flat ground. Open the profile to see the exact blocking point and its height, then raise a tower or adjust clearance.
The terrain model is bare-earth, so trees and buildings are not in the raw data. The clearance margin is there to cover them — increase it in vegetated or built-up areas and always verify the obstruction on site before deployment.
Connecting two points when a single hop is blocked.
A relay is an intermediate point that breaks one blocked path into two clear hops (A → Relay → B). Use it when a hill or building sits between your sites and no realistic tower height clears it.
It highlights the feasible regions where a relay could sit so that both hops pass, then lets you place the relay where it is practical — on an existing tower, rooftop or high ground. It is guidance for an operator, not a blind auto-placement.
Yes. Relay links scale naturally — A → R1 → R2 → B and beyond — and the report represents each hop in sequence so the whole chain reads as one deliverable.
Turning an analysis into a deliverable you can send.
You can export a PDF for sharing, an editable Word document for survey handover, and a KMZ to open the geometry in Google Earth. Each is generated from the same analysis, so they stay consistent.
Use PDF when you want a fixed, professional report to send to a customer. Use Word when the survey team needs to add notes, checkpoint results or edits before finalising.
KMZ opens your sites, link path and relay geometry directly in Google Earth, so you can inspect the route in 3D or share it with anyone who uses Earth. It is the geographic companion to the written report.
Yes — report branding, letterhead, watermark and which sections appear are configured centrally, so every report your organisation exports looks consistent and on-brand.
Export the PDF and send it directly, or use the WhatsApp share where available to pass a link and summary in one tap. KMZ is best when the recipient wants to explore the route themselves.
Taking a feasible route from desk to deployment.
On mobile, open the Alignment Guide and choose whether you are at Site A or Site B. It gives you the azimuth (compass bearing) and tilt to point the device at the far end.
Confirm PASS, review the profile clearance and the blocking points, check the device fit and any urban checkpoints, then carry the report to site to verify trees and buildings in person.
Yes — the bulk analyser processes many site pairs together, so you can screen a whole list of candidate routes for feasibility before planning any field visits.
