Use case · Site-survey reduction

Replace site visits with desk-grade 3D data

Physical site surveys eat rollout budget and timeline. rfMAP gives RF planning teams survey-grade, sub-meter 3D data, with QA and registration built in, so line-of-sight, clutter and micro-mapping analysis happen on the desk and fewer field visits are needed.

The stakes

Site surveys are eating the rollout

Every planning team knows the line: physical site surveys are eating our rollout budget and timeline. A truck rolls to a candidate location, a crew measures, and the planning question waits days for an answer that a single trip can only partly settle.

5G makes this worse, not better. Cells reach only 300 to 500m and die on line-of-sight, so blockage by trees and buildings has to be checked location by location. Surveying every one of those by hand does not scale to a national rollout.

The desk alternative

What survey-grade 3D data resolves before anyone leaves

Line of sight

LOS and Fresnel, on the desk

Run line-of-sight and Fresnel analysis against 3D buildings and vegetation heights, so blockage is known before a candidate is ever visited.

Clutter

Clutter the planner can trust

Up to 35 land-use clutter classes describe the ground the signal actually crosses, replacing assumptions a single site visit cannot generalise.

Micro-mapping

Micro-mapping at sub-meter precision

Sub-meter accuracy and per-building multi-polygon detail let teams reason about individual structures, not street centerlines.

Terrain

The full surface and the bare earth

DTM, DSM/Clutter Height, 4D bridges, 3D buildings, 3D vegetation with heights and 2D vectors give one coherent model of the planning area.

The objection, head on

Is satellite-derived data accurate enough?

It is the first question every RF lead asks, and rightly so. rfMAP is built from high-resolution multi-stereo satellite imagery at sub-meter accuracy, with QA and registration workflows that keep every layer correctly placed. Buildings are modeled as per-building multi-polygons and vegetation is captured in stacked polygons with heights, so the data carries the structure that line-of-sight analysis depends on.

This is authentic geodata, not a flattened basemap. It is the standard that lets planning teams treat a desk analysis as a survey, rather than a guess that still needs the truck.

Survey-grade, on desk

From field to desk, the survey replaced by data.

Most candidate visits collapse into one model the whole team plans against. Line-of-sight, clutter and micro-mapping resolve at the desk, on data that carries the same structure a survey would have measured.

The outcome

Fewer trucks, optimal placement in less time

When the analysis lives on survey-grade data, the team makes fewer physical site surveys and reaches optimal placement in minimum time. The trips that remain are the ones that genuinely need a crew, not the ones a desk could have settled. For fixed wireless access in particular, line-of-sight qualification runs entirely on the desk before any visit is scheduled.

Proven at deployment scale

The dataset under India's 5G build

This is the same 3D data RF planning teams rely on across major rollouts. Lepton's 3D dataset underpins more than 95% of India's 5G deployment, and the maps span 128 countries and 3150 cities, so desk-grade analysis holds up at the scale of a national network build.
