5G NR Throughput Estimator
Calculate theoretical and practical throughput for 5G New Radio deployments.
5G NR Speed Reference
| Band Type | Typical BW | Peak DL | Practical |
|---|---|---|---|
| Low-band (n28) | 10-20 MHz | ~300 Mbps | 50-150 Mbps |
| Mid-band (n78) | 100 MHz | ~2 Gbps | 300-1000 Mbps |
| mmWave (n257) | 400 MHz | ~8 Gbps | 1-4 Gbps |
Based on 4x4 MIMO, 256-QAM, TDD 4:1
5G NR Throughput Formula
3GPP Formula (TS 38.306)
Throughput = J * v * Qm * f * Rmax * (NRB * 12 / Tslot) * (1-OH)
J = carriers, v = layers, Qm = mod order, f = scaling, Rmax = code rate, NRB = PRBs
J = carriers, v = layers, Qm = mod order, f = scaling, Rmax = code rate, NRB = PRBs
5G NR throughput depends on bandwidth (PRBs), MIMO layers, modulation, coding rate, and frame structure. TDD ratio significantly affects DL vs UL split.
Key Parameters
- Numerology: SCS determines slot duration and PRB count
- 256-QAM: 8 bits/symbol for peak rates
- MIMO: Up to 8 layers DL, 4 layers UL
- Overhead: 10-25% for control and reference signals
