Private 5G Network vs Private LTE Network

Saurav Jha

As dedicated business communication networks, private networks or non-public networks help enterprises to facilitate seamless and secure communication between people and things/devices. Both government agencies and private organizations set up their own private networks to secure and scale the communication networks according to their precise needs.

At present, private networks operate using 4G. But 5G will soon use 5G to leverage several new and enhanced capabilities. 5G is all set to transform the private networks by delivering ultra-fast speed, ultra-low latency. But the enterprises will develop 5G private networks based on their existing LTE networks.

A market forecast report released by Mobile Expert suggests that both private LET and 5G markets will grow consistently and simultaneously over the next few years. But most non-public networks will soon use 5G technology instead of 4G technologies to unify enterprise connectivity, secure communication, and optimize services.

The 3GPP Release 16 aims to replace Wi-Fi, private wired Ethernet, and LTE networks with 5G in various industrial environments. 5G will optimize the performance of private networks by delivering three important features – enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (uRLLC), and massive machine-type communications (mMTC).

That is why; the enterprises from various industries will replace private LTE networks with private 5G networks gradually. But the LTE and 5G private networks will coexist seamlessly in the near future. That is why; it is time for you to understand some of the major differences between 5G and LTE non-public networks.

Why Enterprises Will Switch from Private LTE Network to Private 5G Network?

Ultra-Fast Connectivity Speed

5G is reportedly over 10 times faster than 4G LTE. A user can download ultra-high-definition video feeds in seconds over the fifth-generation cellular network. But the user needs about 5 minutes to download the high definition video feeds over the fourth-generation cellular network. The ultra-fast connectivity speed will help enterprises to inspect and monitor remote offsite processes visually. The managers can make informed decisions immediately by performing remote visual monitoring and inspection.

Massive Device Density

While using 4G, a private network can support up to 100000 devices per square kilometers. But a private 5G network will support about one million devices simultaneously. The massive device density will help enterprises to boost human-to-human, machine-to-machine, and human-to-machine communication. The businesses can leverage the massive device density to automate most business processes by connecting devices and sensors seamlessly.

Ultra-Low Latency

5G will reduce latency to one millisecond. The ultra-low latency will enable enterprises to enable real-time interaction between things and sensors. Many enterprises will leverage the key feature of 5G technology to carry out crucial and sensitive operations using robots. The managers can control and manage the robots flawlessly as the data packages will be transmitted from one point to another in one millisecond. 5G will help enterprises to eliminate the latency-issues faced while using the current wireless and cellular technologies.

Six Nines Network Reliability

5G will support a reliability rate of 99.9999%. Also, the technology will reduce expected downtime per year to 5 minutes. The optimal network reliability will help enterprises to automate crucial business operations and boost the performance of high-priority applications. The enterprises can further boost network reliability and reduce expected downtime by creating multiple virtual networks. They will leverage the network slicing feature to use a specific virtual network slice for specific traffic, devices, or services. The enterprises can further optimize each network slice according to requirements and priorities.

Multiple Data Transmission Paths

Unlike current cellular and wireless technologies, 5G will support multiple data transmission paths. The feature will help enterprises to ensure uninterrupted data transmission when one path is blocked or not available. For instance, the enterprises can implement multiple data transmission paths to send and receive data when the primary data transmission path is blocked by a conveyer belt or crane in an industrial environment. The alternative paths will boost machine-to-machine communication by ensuring an instant and uninterrupted data transmission.

Speed of Implementation

The enterprise needs to make provisioning for non-public 5G networks on their own. The in-house provisioning will help businesses to contrail several important aspects of the private network including resource utilization and communication security. Also, the enterprises can simplify and speed up private 5G network deployment through virtualization. The network virtualization will make it easier for enterprises to scale up or scale down the private network capacity according to current needs. Network Function Virtualization (NFV) will create opportunities for enterprises to implement new business models and add new services on demand.

Enhanced Communication Security 

A private 5G network will be more secure than a private LTE network. Unlike current cellular technology, 5G will boost communication security by providing key features like identity management, security assurance, privacy, and resilience. Also, each enterprise has to set up and manage the private networks on its own. Hence, enterprises can easily enhance communication security by implementing solid security policies. For instance, an enterprise can easily prevent targeted security attacks and data breaches by storing both enterprise and automated data in in-house data centers.

Meet Industry 4.0 Requirements

The enterprises have to automate and revamp their business processes and operations to stay relevant in the age of Industry 4.0. They cannot support Industry 4.0 initiatives using Wi-Fi and 4G LTE. The enterprises have to upgrade to a private 5G network to minimize communication downtime, keep enterprise and automated communication separated, and meet the growing communication needs of industrial automation.

According to,

Almost nine in 10 manufacturing businesses in the world’s industrial heartlands want their own private LTE and 5G networks to drive forward Industry 4.0 initiatives and digital transformation.

The 3GPP Release 16 aims to replace private LTE networks with private 5G networks in the future. But the enterprises will use their existing LTE networks as the foundation for developing private 5G networks. Hence, private 5G networks will not make private LTE networks obsolete in the shorter run. The private networks will use 5G instead of 4G, in the long run, to boost enterprise communication by leveraging enhanced and new capabilities.
