It’s been just over five years since Private 5G Networks burst onto the scene, gaining significant attention as part of the broader global rollout of 5G technology.
Despite the abundance of articles, blogs, tutorials, and whitepapers being produced worldwide on Mobile Private Networks (MPNs), especially Private 5G (P5G) Networks, there still seems to be a gap in fully understanding the basics. In this blog post, we aim to provide a comprehensive overview of Private 5G Networks, not only from the standards and industry’s perspective but also through the lens of the end users and how they perceive it.
In today’s digital age, nearly all organizations and enterprises own some or other wired and/or wireless network(s). An enterprise typically consists of Local Area Networks (LANs) and Wide Area Networks (WANs), connecting offices, data centers, and branches. These networks are a mix of wired and wireless connections, allowing authorized users to access data, applications, and services. Security measures, such as firewalls, VPNs, and intrusion detection systems, are essential to protect the organization’s assets.
Enterprise Wireless Networks represent the wireless component of an enterprise’s broader network, enabling mobility and flexibility for users. They typically include Wi-Fi for general office use, and in some cases 4G LTE/5G private networks for specialized use cases that cannot be satisfied with Wi-Fi.
Industrial Networks are a subset of Enterprise Networks, focused specifically on connecting machines, sensors, and control systems in industrial environments. These networks often prioritize operational continuity, low latency, and real-time control, making them critical for automated and mission-critical industrial processes.
In broad terms, Enterprise Networks form the overall infrastructure, with Industrial Networks addressing specific connectivity needs in industrial settings, and Enterprise Wireless Networks offering wireless connectivity that supports both office and industrial environments. Together, these networks ensure seamless communication and operation across various organizational environments.
We rely on our mobile phones for just about everything—calls, messaging, sharing photos, browsing the web, streaming videos, and staying connected with friends and family. All of this is made possible by Public Mobile Networks (PMNs), the vast telecommunications networks that keep us connected no matter where we are. These networks, operated by Mobile Network Operators (MNOs) or Mobile Virtual Network Operators (MVNOs), provide coverage not just for our personal devices, but also for countless gadgets and machines that make up the Internet of Things (IoT).
With the rise of 5G, public networks are evolving to deliver faster speeds, lower latency, and support for massive IoT communication. However, public networks face limitations such as congestion in crowded areas, and they struggle to meet the specific needs of industries that require dedicated resources, ultra-low latency, and enhanced security. This is where private networks come in, offering a solution for a wide range of specialized use cases.
While PMNs are essential for providing widespread connectivity, they typically operate on a “best-effort” basis. This means that while they prioritize broad coverage and availability, they can’t always guarantee specific service levels—especially in high-traffic areas. Public networks are designed to serve a broad range of users, making it challenging to tailor them for the specific needs of enterprises, such as guaranteed bandwidth, ultra-low latency, and more stringent security.
These challenges have led to the emergence of Mobile Private Networks (MPNs). MPNs are dedicated cellular networks built for specific organizations—whether it’s a business, factory, or university—rather than the general public. Unlike public networks that everyone shares, MPNs give enterprises complete control over the network’s coverage, security, and performance, allowing them to customize it to their exact needs.
In our earlier whitepaper, “Private 5G for Enterprises – Becoming Real,” we discussed the key drivers that has motivated organizations to adopt MPNs thereby making them an indispensable part of the modern enterprises and industries.
4G/LTE was a boon for enterprises looking for an alternative to Wi-Fi to solve their connectivity challenges. The simplicity of the 4G/LTE network coupled with greater control, security, flexibility, scalability, and reliability, while also supporting several specialized use cases that public networks cannot adequately address made them immensely popular.
Private 4G/LTE networks were a game-changer for enterprises seeking an alternative to Wi-Fi, offering greater control, security, flexibility, scalability, and reliability. Their ability to support specialized use cases that public networks couldn’t adequately address made them immensely popular. However, limitations in 4G/LTE’s capabilities spurred the development of 5G, which was designed from the ground up to overcome these challenges, thus fueling the momentum for the adoption of Private 5G Networks (P5G) over both Private 4G/LTE and, in many cases, Private Wi-Fi.
While this post doesn’t aim to directly compare MPNs with Private Wi-Fi, it’s important to note that MPNs are not expected to replace Wi-Fi in all cases. Wi-Fi will likely continue to play a role in many environments.
As mentioned, P5G Networks solve many of the limitations of Private 4G/LTE by offering higher speeds, lower latency, better support for larger device densities, increased flexibility through network slicing, and the scalability needed for future technologies. For industries that demand real-time communication, massive IoT connectivity, or mission-critical reliability, P5G represents the next step in their digital transformation.
In our earlier whitepaper, “Private 5G to Help Solve Existential Challenges in the Digital Transformation of Warehouses,” we explained how Private 5G technology has matured significantly over the last 2-3 years. This reductions in the size of radio equipment, power consumption, and significant improvements in hardware reliability has positioned Private 5G as a viable long-term solution. The improvement in the reliability of hardware, the trend toward Softwarization, and the availability of open-source software has made the use of commercial off-the-shelf (COTS) servers a reality, thereby reducing the costs without the need for high-volume deployment.
In addition, a lot of new dedicated spectrum being made available for MPNs is best suited for Private 5G network deployment in comparison to Private 4G/LTE. This dedicated spectrum is a key driver for MPNs and offers an advantage over Private Wi-Fi by improving the availability and reliability of the private network.
The device ecosystem compatible with Private 5G has also expanded significantly in the past year, providing enterprises and industries with more connectivity options for their machinery and equipment. At the same time, the cost of devices has decreased considerably and is expected to drop further as economies of scale continue to take effect.
Finally, we should point out that many different names are used to represent an MPN. We explained this in our earlier blog post and video here.
The architecture of a MPN, though simplified, consists of several key components that work together to enable secure, high-performance communication for enterprise use cases. Let’s look at each of these one by one:
Data (IP) Network: The Data Network is where all enterprise-specific information and applications reside. It can be compared to the internet in public networks, which users access for browsing, shopping, and streaming. In the context of Private 5G, the Data Network stores all user and business-critical data for the enterprise, such as operational data, machine control systems, and applications. The data network may also include cloud-based or edge data centers, allowing for localized computing and lower latency. Enterprise applications, whether running on user devices or on the private network itself, communicate with application servers over this data network. This infrastructure can either be on-premises or hosted externally by a third-party provider.
Core Network (CN): The Core Network (CN) is the control center or “brain” of the mobile network. It handles essential tasks like session management, mobility (ensuring seamless transitions as devices move between coverage areas), and authentication (verifying the identity of connected devices). The core also manages the network’s connection to external data networks, ensuring that applications and services can communicate effectively. In Private 5G, the core network often includes advanced features like network slicing, allowing enterprises to create separate virtual networks for different applications with varying performance and security requirements.
Radio Access Network (RAN): The Radio Access Network (RAN) is responsible for the wireless interface between user devices and the core network. It handles the transmission and reception of radio signals and typically consists of base stations or small cells that communicate with User Equipment (UE). The backhaul connects the RAN to the Core Network and can use high-speed Gigabit Ethernet, fiber optics, or other dedicated transport technologies. In Private 5G, RAN architecture is often simplified with integrated radio nodes that combine the functionality of traditional Base Band Units (BBU) and Radio Units (RU). While public networks might separate these units for scalability, private networks, especially in localized environments, often use all-in-one small cells for easier deployment and cost efficiency.
User Equipment (UE): The User Equipment (UE) consists of any device that connects to the mobile network, such as smartphones, tablets, laptops, industrial sensors, robots, or even autonomous vehicles. These devices communicate over the air interface using the allocated radio spectrum. In Public 5G networks, dedicated licensed spectrum is critical for managing large-scale communication. For Private 5G networks, having access to dedicated spectrum is equally important to ensure high performance, reliability, and minimal interference. Many regulators worldwide have begun allocating specific spectrum bands for private use, encouraging innovation in private network deployments for sectors like manufacturing, healthcare, and logistics.
There is no shortage of Private 5G Networks use cases. From smart manufacturing and industrial IoT to healthcare and smart cities, Private 5G is helping overcome the challenges that Wi-Fi or 4G/LTE solutions are unable to satisfy. Whether it’s automating production lines, supporting autonomous vehicles, or improving remote healthcare services, Private 5G offers the flexibility, scalability, and reliability required to drive digital transformation. With its ability to handle high data throughput, ensure data privacy, and support mission-critical applications, Private 5G is becoming a key enabler for modern, connected operations.
The following chart from GSA’s Private Mobile Networks September 2024 report highlights that the MPNs market has continued to grow as the number of unique customer references for mid and large deployments (with revenue greater than €100,000) has reached 1,489.
In addition to these, other estimates suggest that there are thousands more and even tens of thousands of MPNs worldwide. The bottom line is that there are a lot of these being tested, trialed and deployed.
