PRORF planner · BTS coverage and PtP links

Plan cell coverage over real terrain.

Place a base station, set up its sectors and see the predicted RSRP, SINR and serving sector on the map. Then check any path, or a point-to-point link, with its terrain profile, line of sight and Fresnel zone.

RX 500 m

Illustrative preview. The planner computes these values from terrain data for your own site.

Coverage before the site exists

Set the mast height, sectors and power, and get a prediction for every receiver in the study area.

Terrain on every path

Each receiver gets its own elevation profile, so ridges and valleys shape the result.

Point-to-point links

Check line of sight, Fresnel clearance and expected signal between any two points.

Coverage views

Four views of the same prediction.

Switch views without recalculating, and show every sector or only one.

RSRP

Received signal from the strongest sector. Points under the threshold stay empty.

SINR

Signal against the site’s other sectors at full load, plus noise.

Capabilities

From the antenna to the receiver, step by step.

Sectors

Configure each sector like the real antenna.

Up to six sectors per site. Rotate the whole tower and keep their spacing, or change one sector at a time. Coverage recalculates as you edit.

  • SectorAzimuth, beamwidths, electrical and mechanical tilt, power, gain
  • SiteHeight above ground, 700–3500 MHz, bandwidth, environment
  • Study areaRadius and a receiver grid from 30 to 200 m
Paths

Click any point to see why the signal is what it is.

Inspect a sector’s boresight, or click the map and drag the receiver. The profile shows the terrain between antenna and receiver, the line of sight and the first Fresnel zone.

PtP analysis

Check a link between two points.

Place both ends and set their heights. The analysis estimates signal, throughput and link quality, and gives the azimuth and tilt to aim each antenna.

How it works

From a point on the map to a coverage prediction.

01

Place the site

Open the BTS planner from Tools on the map and set the mast position, height and frequency.

02

Shape the sectors

Point each sector and set tilt and power. The map updates with each change.

03

Inspect and export

Click paths to see terrain and losses, switch views, and export the prediction as GeoJSON.

Model

How the prediction is made.

The BTS planner and the PtP analysis share one calculation, so the same path gives the same loss, diffraction, line of sight and Fresnel result in both.

  • Terrain

    Elevation from Mapzen Terrain Tiles, sampled about every 30 m along each path, with Earth curvature. Site and receiver ground heights are sampled separately.

  • Propagation

    COST-231 path loss for urban, suburban or rural environments, plus Deygout diffraction over the obstacles in the profile.

  • Antennas

    A generic sector pattern built from horizontal and vertical beamwidth, with electrical and mechanical tilt added together.

  • Signal

    RSRP from EIRP over the configured bandwidth. SINR assumes the site’s sectors transmit at full load, with a 7 dB receiver noise figure.

Know the limits

This is a theoretical model, not a calibrated survey. Buildings, measured antenna patterns, interference from other sites and network load are not modelled, and COST-231 is extrapolated outside its nominal range. Terrain detail depends on the source data.

To check a prediction, compare it with the community measurements on the Signalcrow map.

Use cases

When it is useful.

New sites and small cells

Compare mast positions and heights before a site survey.

Azimuth and tilt tuning

See how a few degrees of tilt move coverage and overlap between sectors.

Terrain shadows

Find the slopes and valleys a site cannot reach, and how much diffraction costs.

Rural and fixed-wireless links

Check whether a roof antenna sees the tower, and which antenna gain it needs.

Coverage at home from a known tower

Run a PtP analysis from the mast to your home with a phone antenna.

Training and teaching

Show how frequency, height and terrain change a link, with numbers for each path.

Plan the site before anyone climbs the mast.
