Private cellular networks began as an alternative to traditional public cellular and WiFi networks. With the advent of 4G LTE and 5G, enterprises sought a solution that provided more control, security, and performance. By utilizing cellular technology to establish localized, on-premises networks, businesses could create a dedicated system tailored to their needs.
The Federal Communications Commission (FCC) further accelerated this shift by designating the Citizens Broadband Radio Service (CBRS) in the U.S., which allowed businesses to use this spectrum for private LTE networks. Other countries have also adopted similar regulations, providing shared spectrum opportunities for private cellular deployment.
Today, private networks are seen as a robust alternative to WiFi in areas such as manufacturing, logistics, healthcare, and smart cities, offering organizations greater control and more reliable coverage.
What is Private Cellular Networking?
Private cellular networking refers to the deployment of cellular networks that are exclusive to a business or organization. These networks leverage 4G LTE and 5G technology, allowing enterprises to benefit from high-speed, low-latency, and highly secure connections without relying on public networks. A private network can be designed to operate on licensed, unlicensed, or shared spectrum, with CBRS being one of the most popular shared spectrum options in the U.S.
Unlike WiFi, which can suffer from interference and limited range, private cellular networks provide consistent coverage across large facilities, ensuring seamless connectivity for employees and IoT devices.
Key Components of a Private Cellular Network
To establish a private cellular network, organizations need the following essential components:
- Cellular Access Points (CAPs): These are small cells or micro-towers that provide coverage, allowing devices such as routers, smartphones, or IoT devices to connect. They can be deployed indoors or outdoors, depending on the network’s needs.
- Cellular Core: Often described as the “brains” of the network, the cellular core manages policies that determine which devices have access and how traffic flows. This can be located on-premises or in the cloud.
- Endpoints: Devices like routers and smartphones must be equipped with private SIM cards to connect to the network. These devices often support CBRS and other frequency bands specific to private cellular networks.
- Private SIM Cards: These SIMs authenticate devices on the network and can either be physical cards or eSIMs.
- Network Management Tools: A unified, cloud-based management platform allows IT teams to configure, troubleshoot, and monitor the network, ensuring optimal performance and reliability.
Benefits of a Private Cellular Network
Private cellular networks offer several advantages that make them an ideal choice for enterprises seeking greater control over their connectivity solutions:
- Enhanced Wireless Coverage: Traditional WiFi networks often struggle with coverage, particularly in large environments. Private cellular networks provide broader and more reliable coverage, ensuring seamless connectivity for all devices, including those in remote areas of the facility.
- High Speed and Low Latency: With 4G LTE and 5G technology, private networks provide high data transfer speeds and low latency, critical for real-time applications like video conferencing, remote monitoring, and IoT devices.
- Massive Data Transfers in Real-Time: The ability to handle large volumes of data in real-time is essential for enterprises managing IoT, video streams, and predictive analytics. Private cellular networks offer the bandwidth needed to accommodate these demands effortlessly.
- Security and Control: Security is a major concern for businesses, and private cellular networks offer superior protection compared to public WiFi. With encryption, authentication, and customizable security protocols, organizations can safeguard sensitive data and control who accesses their network.
- Flexibility with CBRS and Spectrum Options: In addition to CBRS, businesses have other spectrum options like the 900 MHz band, which allows for greater flexibility in network deployment. This ensures that organizations can tailor their private networks to meet specific needs.
- Seamless Switching Between Networks: Many private cellular network devices, such as routers, can switch between private and public networks, offering versatility and ensuring uninterrupted connectivity. For instance, fleet vehicles can use public cellular networks on the road and switch to the company’s private network when in-house.
How to Deploy and Operate a Private Cellular Network
Deploying a private cellular network requires careful planning, integration of key components, and consideration of organizational needs. Here are the steps to ensure successful deployment:
- Assess Needs and Coverage Requirements: Determine the size of the area that needs coverage, the number of devices that will connect, and the type of applications that will run on the network.
- Choose the Right Spectrum: Depending on your region and regulatory environment, choose between licensed, unlicensed, or shared spectrum. CBRS is a common option in the U.S., but other bands like the 900 MHz spectrum might be more suitable based on your needs.
- Deploy Cellular Access Points: Install CAPs across your facility to ensure consistent coverage. Indoor and outdoor cells may be needed depending on your operational environment.
- Configure the Cellular Core: Set up the core either on-premises or in the cloud, based on security and control requirements. Configure policies for network access, traffic management, and resource allocation.
- Integrate Endpoints and Private SIMs: Ensure that devices connecting to the network are equipped with private SIMs. Routers, smartphones, and other devices should be CBRS-compatible for seamless connectivity.
- Use Network Management Tools: Leverage cloud-based platforms to monitor network performance, configure settings, and troubleshoot issues. This will help maintain the health of the network and optimize its performance.
Industry Applications and Future Potential
Private cellular networks are already being used in industries such as manufacturing, healthcare, logistics, and smart cities. The combination of reliable coverage, enhanced security, and high performance is transforming operations in these sectors. As 5G technology continues to evolve, private networks will play an even more critical role, enabling innovations like autonomous vehicles, smart infrastructure, and advanced IoT ecosystems.
Unlocking the Future of Connectivity with Private Cellular Networks
Private cellular networks offer enterprises a unique opportunity to take full control of their connectivity needs. With the ability to customize and secure their own networks, businesses can enjoy reliable, high-speed, and low-latency connections tailored to their specific requirements. As the demand for data grows, private cellular networks will continue to revolutionize enterprise connectivity, driving innovation and efficiency across industries. Whether operating on licensed, unlicensed, or shared spectrum, the future of enterprise connectivity lies in private cellular networking.
