LTE / 5G NR Coverage Radius & Site Count Calculator

Free – no sign-upRuns in your browser

Estimate LTE and 5G NR cell radius from a downlink RSRP and uplink link budget, inter-site distance and number of sites for an area.

Open the tool → See all tools

Enter transmit power, antenna gain, height, environment and indoor penetration. The calculator computes the maximum allowed path loss for DL and UL, applies a propagation model and returns the limiting radius and the number of 3-sector sites needed.

What it does

DL budget from RS / SSB EPRE and the cell-edge RSRP target
UL budget from UE power, PRB allocation, noise figure and required SINR
Okumura-Hata, COST-231 Hata and 3GPP TR 38.901 UMa models, 4 environments
Penetration (car / indoor / deep indoor) and shadowing margins
Inter-site distance, area per 3-sector site and number of sites for a target area

Is it really free?

Yes – this tool is free to use without an account.
