Why Private Cellular Networks Are Gaining Ground in Manufacturing and Warehouse Environments

When the flow of goods halts or production lines grind to a stop, the cost is measured in more than just dollars—it’s lost time, missed opportunities, and unhappy customers.

Wireless connectivity is a huge part of keeping operations running smoothly, but for many manufacturing and warehouse facilities, WiFi alone isn’t cutting it, and many are turning to private cellular networks.

Private cellular networks are reliable, secure, and scalable solutions designed to keep everything stays connected, and productivity and production never miss a beat. 

How WiFi Can Struggle in Certain Environments

WiFi has long been the go-to for connectivity—and for good reason—but it wasn’t necessarily built with manufacturing plants or sprawling warehouses in mind.
 

• Interference from Materials: WiFi signals struggle with environments heavy in metal, water, or paper—materials that absorb or deflect signals. Which means places with a lot of metal shelving, pallets of paper goods, or water used in some industrial processes are at a disadvantage when it comes to reliable and consistent WiFi.
   

• Coverage Limitations: Large outdoor spaces, like shipping yards, or expansive indoor facilities require many multiple access points to maintain coverage. This usually creates gaps and increases the risk of dropped connections.
   

• Congestion in High-Density Areas: Warehouses filled with IoT sensors, handheld scanners, and connected robotics can overwhelm WiFi, leading to network slowdowns and unreliable connections.
   

• Operational Challenges: Welding processes, heavy machinery, and mobile robots will often create electromagnetic interference that disrupts WiFi performance.
   

While these challenges are technical—they obviously directly impact productivity, creating delays, downtime, and inefficiencies. 

Private Cellular Advantage 

Private cellular networks (LTE and 5G) solve a lot of these pain points, offering strong connectivity that can also scale with the demands of modern manufacturing and warehousing. 

Reliable Coverage 

Private cellular networks provide wide, uninterrupted coverage, eliminating dead zones that are typically found in WiFi networks. This is especially important for larger facilities or outdoor areas, such as staging zones, distribution hubs, or outdoor warehouses, where WiFi coverage may falter. 

Performance Under Pressure 

With lower latency and higher device capacity, private cellular networks handle IoT-heavy operations more efficiently than WiFi. They support thousands of devices without the bottlenecks common in WiFi environments.

Built-In Security 

Security is built into the foundation of private cellular networks. SIM-based authentication is automatic, ensuring only approved devices connect. With dedicated spectrum and controlled access, private cellular networks simplify protection while isolating traffic from public threats.

WiFi security often get a bad rap due to vulnerabilities associated with public WiFi networks—but in reality, enterprise-grade WiFi can be highly secure when properly configured. These protections do require ongoing effort and expertise to ensure consistency.

Reduced Interference 

Unlike WiFi, private cellular networks can operate well even in environments with heavy machinery, water, or materials that would typically degrade signal quality. 

WiFi + Private Cellular 

While private cellular networks bring unique strengths to industrial environments, WiFi still has its place. Combining the two can create a failsafe system, ensuring connectivity when you need it most.

• Primary vs. Secondary Roles: Use private cellular for mission-critical operations like robotics, safety systems, and inventory management, while reserving WiFi for guest networks or non-essential tasks.
   

• Failover Redundancy: In the rare event of a network failure, having both systems in place provides a backup to keep operations running.
   

A Real-World Example: Ericsson Enterprise Wireless + HBS Solution for HRTLP 

Heartland Label Printers faced recurring issues with dropped WiFi connections in its Little Chute, Wisconsin warehouse. After implementing a private cellular network solution developed by Ericsson and HBS, they eliminated connectivity gaps, boosted productivity, and smoothly integrated IoT technologies into their operations.
 

The result? Reduced downtime, enhanced security, and a scalable network built for the future.
