Capacity planning utility for E-UTRAN/NR Dual Connectivity (EN-DC), modeling the aggregated downlink and uplink throughput across LTE (MCG) and NR (SCG) radio legs.
EN-DC throughput calculators estimate dual-connectivity capacity for LTE MCG + NR SCG (Option 3X), giving engineering bounds for NSA deployments before backhaul sizing.
The calculator models the MAC-layer aggregation of LTE and NR component carriers, applying spectral efficiency values from 3GPP tables to derive the combined peak and average throughput.
Built on 3GPP Technical Specifications, ensuring accuracy for production deployments and security audits.
Calculations specifically designed to identify protocol vulnerabilities and signaling misconfigurations.
Critical for operators running 5G NSA via Option 3x (LTE anchor with NR data). Supports capacity planning for mixed-traffic deployments where both MCG and SCG serve the same UE.

LTE 20 MHz 4x4 plus NR 100 MHz 4-layer may advertise multi-Gbps peaks; with 0.6 load factor the busy-hour average for transport can be far lower—and that average is what you order.
Does not simulate scheduler fairness or interference. Validate with vendor EN-DC KPIs.
EN-DC aggregates an LTE master cell group (MCG) with an NR secondary cell group (SCG). User throughput is not a simple sum—control stays on LTE while NR adds capacity subject to dual-connectivity overhead and radio conditions.
Use it only as an upper bound. Split-bearer flow control, PDCP aggregation limits, and UE capability caps reduce the realized aggregate.
Dimension S1-U/X2-U (or NG equivalents in evolution paths) for the busy-hour aggregate with contention factors, not marketing peak alone.
Estimate peak 5G NR user data rates and spectral efficiency based on 3GPP TS 38.306 standards.
