4G LTE vs. Industrial 5G: The Question Every Infrastructure Manager Is Asking

5G regularly makes headlines in industry publications. Theoretical speeds of 10 Gbps and latencies of 1 ms sound like a dream—but will they match the reality of your industrial deployments in 2025? This guide offers an honest comparison based on actual performance measured under French industrial conditions.

Technical Comparison: 4G LTE vs. Industrial 5G

Critère	4G LTE	5G NSA	5G SA
Downstream flow rate	150 Mbps (Cat. 4) / 600 Mbps (Cat. 12)	300–1,000 Mbps	1–10 Gbps
Typical latency	20 – 50 ms	10 – 30 ms	< 10 ms
Coverage in France (2025)	99% of mainland France	~50% (major cities)	~15% (major cities)
Cost of an industrial router	300 – 600 € HT	800 – 1 500 € HT	1 200 – 2 500 € HT
M2M SIM Availability	Mature, optimized multi-operator systems	Limited, higher rates	Very limited
Ideal Use Case	SCADA, VPN, monitoring, HMI	HD video, mobile assets	Robots, private factory networks
Ecosystem Maturity	Very mature (10+ years)	In development	Émergent

Conclusion: For 90% of current industrial applications, 4G LTE is the best technical and economic solution. 5G will become relevant once SA coverage becomes widespread in industrial areas—an estimated timeline of 2027–2028 for France.

What 4G LTE Already Covers Perfectly

4G LTE Cat.4 at 150 Mbps is more than enough for:

• SCADA Monitoring: Industrial control systems operate on cycles ranging from 100 ms to 1 s—the 4G latency of 20–50 ms is more than sufficient
• Remote HMI Access: A VNC session to an HMI requires 2–5 Mbps, well below the 150 Mbps available on 4G
• IoT Telemetry: Sending sensor readings every second consumes a few kilobits per second
• File transfer: production reports, images, firmware—Cat.12 (600 Mbps) can even handle large files
• Site-to-site VPN: an encrypted tunnel to the cloud platform with bandwidth well above what’s needed

For these applications, switching to 5G would not noticeably improve the user experience, but it would double or triple the hardware costs.

When 5G Offers a Real Advantage

Industrial 5G (and more specifically, 5G SA with a dedicated core network) offers measurable benefits in very specific scenarios:

Real-Time Robot Control — Haptic teleoperation of robotic arms requires a latency of <5 ms. With 5G SA, a latency of 1 to 3 ms enables applications that are impossible with 4G.

4K Industrial Video Surveillance — Quality control using computer vision with multiple simultaneous 4K cameras requires several hundred Mbps. Only 5G can reliably provide this bandwidth.

Private Factory Networks — Dedicated-band 5G (MFCN 3.8–4 GHz in France) enables the creation of a private network within a factory featuring hundreds of high-density IoT sensors and QoS guarantees that public Wi-Fi or 4G cannot provide.

Industrial Autonomous Vehicles — Communicating AGVs (Automated Guided Vehicles) require ultra-low latency and guaranteed availability, which are incompatible with shared 4G networks.

The Cloud-First Strategy: Protect Your Software Investment

Whatever you decide today (4G or 5G), the most important thing is to choose a hardware-agnostic cloud platform. With Eziwan, your network configuration (VPN, APN, firewall rules, SCADA integrations, alerts) is stored in the cloud—not in the router itself.

This means that if your area switches to 5G SA coverage in two years, you can:

1. Order Eziwan 5G routers
2. Ship them to the site and plug them in
3. They automatically retrieve their configuration via ZTP in less than 5 minutes
4. No reconfiguration, no technician intervention

This approach prevents you from having to start from scratch during the 4G-to-5G migration and protects your investment in SCADA integrations and network policies.

Quick Decision Guide

Choose 4G LTE if your application involves SCADA, monitoring, VPN, remote HMI, alarms, or IoT telemetry; if your site is in a rural or suburban area; if your fleet has more than 10 sites; or if you have a limited hardware budget.

Choose 5G if your application requires latency of <10 ms (robots, haptics), a data rate >500 Mbps (multi-stream 4K video), or a high-density private factory network — AND if your site has 5G SA coverage confirmed by the carrier.

If in doubt: Deploy 4G LTE using the Eziwan platform, and migrate to 5G site by site as coverage becomes available—without having to reconfigure your cloud setup.
