Factory of the Future with Dedicated Local Private Networks for Industrial Automation
Introduction
The fast-paced evolution of Industry 4.0 has changed the game for factories. With needs ranging from real-time monitoring to predictive maintenance, industries are on the lookout for solid, secure, and quick connectivity options. Traditional public networks often can't keep up, falling short with congestion, inconsistent performance, and limited control.
This is where dedicated local private networks step in as a game-changer for industrial automation.
The diagram included shows how factory devices connect through a dedicated local RAN (Radio Access Network) and a core network. This setup allows for IIoT (Industrial Internet of Things) analytics, data management, and enterprise services. It seamlessly links operational technologies (OT) with enterprise IT systems, paving the way for the factory of the future.
What is a Dedicated Local Private Network?
A dedicated local private network is a communication system designed specifically for an enterprise or industrial setting. Unlike public cellular networks, it offers:
Exclusive spectrum allocation or shared spectrum use with specific QoS (Quality of Service) settings.
Complete control over network resources to ensure security and reliability.
On-premises infrastructure that lessens dependency on outside operators.
Ultra-reliable low latency communication (URLLC), which is key for automation and robotics.
This type of network is the backbone of industrial automation because downtime or poor connectivity can lead to costly production delays.
Architecture of the Factory of the Future
The image depicts a four-layer structure for the dedicated local private network aimed at industrial automation:
- Devices Layer
Covers various factory devices:
Sensors (like temperature, motion, and vibration).
Industrial robots and actuators.
Cameras for monitoring and quality checks.
Smartphones and tablets for operator interfaces.
Communication happens through several technologies:
ZigBee for low-power sensor communication.
Wi-Fi for high-throughput local connections.
BLE (Bluetooth Low Energy) for energy-efficient short-range data transfer.
Wired connections for critical, latency-sensitive operations.
- Dedicated Local RAN
Serves as the access layer connecting devices to the private network.
Utilizes small cells, access points, or local 5G radios.
Guarantees coverage within the industrial site, while maintaining controlled latency and bandwidth.

Challenges in Deploying Dedicated Local Private Networks
Although private networks provide transformative benefits, they do come with challenges:
Deployment Costs: Initial setup of private RAN and core infrastructure can be high.
Spectrum Licensing: Companies may need regulatory approval.
Integration Complexity: Merging OT systems with IT infrastructure can be tricky.
Skill Gaps: There's a need for workforce training in telecom-grade networking.
Telecom operators and vendors are tackling these issues by offering managed private network solutions, which include deployment, operation, and lifecycle support.
How 5G Strengthens the Factory of the Future
Integrating 5G with private networks speeds up industrial automation:
URLLC (Ultra-Reliable Low-Latency Communication): Guarantees instant responsiveness.
Massive Machine-Type Communication (mMTC): Supports a vast number of connected devices.
Network Slicing: Dedicates specific resources for crucial industrial applications.
Edge Computing Integration: Brings computation closer to the factory, further minimizing latency.
This combination of 5G and dedicated local private networks lays the groundwork for Industry 4.0 and beyond.
