At first glance, Wi-Fi and LTE/5G seem to fulfill the same purpose: transmitting data. But their uses and benefits are profoundly different.
Wi-Fi: A Localized Solution
Wi-Fi is designed for small spaces such as offices, homes or small shops. Its installation cost is relatively low, and it is simple to deploy. However, it shows its limitations when subjected to demanding conditions, such as high device density or complex environments.
LTE/5G: A Revolution in Motion
LTE and 5G, on the other hand, rely on licensed frequencies and dedicated infrastructures that offer stable, highly secure and fast connectivity over long distances. They can handle a high density of devices, with ultra-low latency (time between data being sent and received), essential for mission-critical applications where every millisecond counts, such as remote vehicle operation, real-time data management or industrial process automation.
Comparing is Deciding
Features | Wi-Fi | Private LTE/5G |
Underground range | 50 to 100 meters | Up to 5km (with omnidirectional antennas) |
Above-ground range | 300 to 500 meters | 5 to 20 km (with omnidirectional antennas) |
Reliability | Sensitive to interference | No interference thanks to licenced bands |
Security | Good (with WPA3) | very high (complete control over data and advanced encryption) |
Installation cost | Relatively low if the solution is localized | Higher initial cost, but greatly increased profitability in the case of medium or large networks |
Required infrastructure | Requires multiple access points | Extended/wide range, less equipment & infrastructure required |
Number of connected devices | Limited, possible congestion | Optimal for a great number of connected devices |
Equipment lifecycle | Frequent end-of-life with limited updates | Long-term equipment support |
Adaptability to critical environments | Limited | Designed for challenging environments with critical operations |
Why opt for a private rather than a public LTE/5G network?
While public LTE and 5G networks are well known to cell phone users, private networks are distinguished by their exclusive and personalized nature, as they are built specifically for a specific business/environment.
Unlike public networks that can be shared by millions of users, a private network offers enhanced security, greater reliability and tailored performance.
Public Network
PROS
– Easily accessible
– Ideal for personal or non-critical needs
CONS
– Congestion during peak hours
– Increased vulnerability to cyber attacks
– No control over quality of service
– Low customizability
Private Network
PROS
– High security and complete control over data
– Optimized for mission-critical requirements: automation, remote operation, IoT, etc.
– Stable & reliable performance, independent of public usage
– Easy troubleshooting and maintenance
– Long-term savings: fewer access points and optimized infrastructure reduce operating costs
Wi-Fi : Insufficient for industries with mission-critical operations
In harsh industrial environments such as underground mines, the limitations of Wi-Fi become obvious. Installing multiple access points to cover a vast area is not only costly, but also unpredictable, and compromises essential operations such as remote operation, real-time asset tracking and predictive maintenance, all of which are vital to worker safety and operational efficiency.
In contrast, private LTE and 5G networks enable these solutions to be deployed with unrivalled reliability.
