5G NR Throughput vs EN-DC
Pure NR peak-rate math and EN-DC aggregation answer different questions in NSA vs SA planning.
Use the NR Throughput calculator for single-carrier (or NR-only) TS 38.306 style peaks. Use EN-DC when the UE aggregates an LTE MCG with an NR SCG (Option 3X)—capacity is not a naive sum, and X2-U/midhaul often binds first.

EN-DC Aggregated Capacity
Dual-connectivity aggregate for LTE+NR NSA, including the reality that control stays on LTE while NR adds capacity.

How to choose
If the site is SA NR only, stay on NR Throughput (+ link budget). If handsets still depend on LTE anchor with NR SCG, run EN-DC and then size X2/Xn transport. Never present EN-DC as NR-only peak.
FAQ
Can I add LTE Mbps to NR Mbps?
Only as a loose upper bound. Flow control, UE caps, and radio conditions reduce the realized aggregate.
Which tool for transport BOM?
EN-DC busy-hour averages plus X2/Xn sizing—not marketing NR peaks alone.
Does FR2 change the choice?
FR2 still uses NR Throughput for the NR leg; EN-DC applies when LTE anchor remains.
