Private 5G networks: the future of industrial connectivity

In the fast-moving world of industrial communications, private 5G networks are emerging as a game-changing technology. As founder and CEO of TelcoKnowledge, I have seen their transformative potential first-hand. Here are some insights on the current state of private 5G networks and why they matter more and more in industrial environments.

The growth trajectory

According to SNS Telecom & IT, private 5G is set for rapid growth: a compound annual growth rate of around 42% between 2024 and 2027, with annual spending reaching about $3.5 billion by the end of 2027. The main driver is localised 5G networks in manufacturing and process industries for Industry 4.0 applications.

Why private 5G?

Private 5G networks offer clear advantages over traditional wireless technologies:

1. Performance. Low latency, high reliability and high connection density suit industrial applications.
2. Security. A dedicated network gives better control over data and operations.
3. Scalability. 5G accommodates the growing number of IoT devices on industrial sites.
4. Customisation. The network can be tailored to specific industrial needs and use cases.

Real-world impact

The benefits are already visible across industries:

• Manufacturing. At Tesla's Gigafactory Berlin-Brandenburg, private 5G helped overcome up to 90% of over-cycle issues in one General Assembly process.
• Agricultural machinery. John Deere plans to move its Davenport Works factory from 70% wired Ethernet to 80% cellular, 10% Wi-Fi and 10% Ethernet.
• Aviation. Lufthansa Technik's 5G campus network in Hamburg lets customers join engine inspections remotely, in high-definition video, without travelling to the site.
• Logistics. At the East-West Gate intermodal terminal in Hungary, productivity rose from 23–25 to 32–35 containers per hour, and personnel operating costs fell by 40%.

Global adoption and innovation

China leads in private 5G maturity, but other countries are catching up fast. The US, Germany, France, Japan, South Korea and Taiwan are all seeing wider adoption across industrial sectors. Some companies are already testing 5G Advanced features for time-critical industrial control.

Challenges and opportunities

Challenges remain: a limited range of non-smartphone devices, high 5G IoT module costs, and a shortage of cellular expertise inside end-user organisations. Each of these is also an opportunity for innovation and specialist support.

Looking ahead

Towards 2030, private 5G networks are set to become the foundation for Industry 4.0 and advanced industrial applications. Their ability to support use cases from autonomous mobile robots to augmented-reality-assisted maintenance makes them a critical enabler of industrial digital transformation.

At TelcoKnowledge we help enterprises navigate the complexity of adopting private 5G networks. The future of industrial connectivity is here, and it runs on private 5G.
