RF Wireless 4G & 5G Calculators

LTE and 5G NR throughput, path loss, link budgets and drive-test tools. Free calculators with formulas and worked examples.

Signal and link

RSRP, RSRQ and RSSI CalculatorRSRQ = N × RSRP ÷ RSSI, in dB. Enter two and read the third.SINR CalculatorAdd up interference and noise, then see the SINR.Thermal Noise and Receiver Sensitivity CalculatorHow weak a signal can the receiver still decode?dBm Adder (Power Sum) CalculatorCombine dBm values correctly, in milliwatts.EIRP and ERP CalculatorHow much power does the antenna effectively radiate?Feeder and Jumper Loss CalculatorAdd up the losses between the radio and the antenna.VSWR and Return Loss CalculatorCheck antenna and feeder match from one number.

Throughput and capacity

LTE Peak Throughput CalculatorWhat can an LTE carrier deliver?5G NR Throughput Calculator (3GPP 38.306)Peak NR rate for a carrier, with TDD downlink share.EN-DC (5G NSA) Combined Throughput CalculatorAdd the LTE anchor rate to the NR secondary cell.Cell Capacity from SINR CalculatorUse the Shannon limit with realistic efficiency to size a cell.

Frequency and planning

LTE EARFCN to Frequency CalculatorDecode drive-test and OSS channel numbers.NR-ARFCN to Frequency Calculator (5G)Decode SSB and carrier NR-ARFCN values.PCI Planner (mod 3, mod 6, mod 30)Avoid PCI collisions and confusion between neighbouring cells.Timing Advance to Distance Calculator (LTE / NR)How far is the UE from the site?

Propagation and coverage

Hata Path Loss and Cell Range Calculator (150–2000 MHz)Macro-cell propagation for LTE bands such as 700, 900, 1800 and 2100 MHz.5G NR Path Loss Calculator (3GPP UMa)Path loss and range for 3.5 GHz and other NR bands.LTE / 5G Link Budget and MAPL Calculator (DL and UL)Find which link limits your coverage, uplink or downlink.Antenna Downtilt CalculatorSet tilt so coverage reaches the edge without overshooting.Fresnel Zone and Microwave LOS Clearance CalculatorIs the path clear of obstructions, with 60% of the first Fresnel zone?Radio Horizon and Line-of-Sight Distance CalculatorHow far can two towers see each other?

5G NSA

NSA Coverage Gap Calculator (NR vs LTE Anchor)Where does your 5G NSA service stop working, and why?5G NSA (EN-DC) KPI CalculatorMeasure how well 5G NSA is working on the LTE anchor.5G NSA (EN-DC) Issue SolverA troubleshooting guide for 5G NSA where LTE is the anchor.

Drive test

Drive Test RSRP Coverage Quality CalculatorClassify drive-test samples and report coverage percentages.Lee Sampling Rate Calculator for Drive TestsMake sure your drive-test logging is fast enough for the speed and band.Pilot Pollution and Cell Dominance CalculatorToo many strong cells at one location means poor SINR and unstable handovers.Handover (A3 Event) Margin CalculatorWill the UE report a better neighbour, or is the margin too tight?

KPIs

LTE KPI Calculator (Accessibility, Retainability, Mobility)Turn OSS counters into the KPIs your report needs.

About these calculators

Daily RF engineering maths for planning and optimisation teams: LTE and 5G NR throughput, EARFCN and NR-ARFCN, PCI planning, RSRP and SINR, propagation models, link budgets, antenna tilt and drive-test sampling. Formulas follow 3GPP specifications where noted; field results depend on your network.

Each calculator explains its formula, includes a worked example and lists its sources. Read how we check them on our editorial policy page, or browse all calculators.
