Private 4G/5G Networks: Top 15 Frequently Asked Questions (FAQs)

As businesses and industries seek faster, more secure, and scalable connectivity solutions, private 4G and 5G networks are emerging as front-runners. These networks provide dedicated bandwidth, enhanced security, and tailored solutions to meet the unique operational needs and customizable solutions of businesses. Whether you’re curious about how private networks differ from public cellular or WiFi or want to explore their potential applications, these FAQs dive into the most common questions to help you better understand the world of private 4G and 5G networks. 

‍

What is a Private Network?

At its core, a private cellular network is a dedicated cellular network infrastructure that uses 4G LTE or 5G technology to provide coverage to a specific organization or area 

‍

Private vs. Public Cellular Networks: What's the Difference?

Private networks are designed for the use of a specific organization and access to it is determined by the organization, whereas public networks such as AT&T, Verizon, and T-Mobile are accessible to the general public and shared by multiple users.

A private network generally offers enhanced security, reliability, and control, compared to public networks.

‍

How Do Private Cellular Networks Work?

Private cellular networks rely on the same 4G LTE or 5G technology that public cellular networks depend on. Components like the Radio Access Network (RAN) and core network form the primary infrastructure of a private cellular network as well, but the key difference is these components are managed and operated by an organization or their chosen partner.

Private networks use the same 4G LTE or 5G components as public networks, including:

The key difference: private networks are managed and operated by the organization or its chosen vendor.

‍

How Much Does a Private Cellular Network Cost?

Costs vary significantly based on coverage area, capacity requirements, underlying technology (4G vs 5G), and deployment model. Initial investments can range from tens of thousands to millions of dollars. Costs depend on factors like:

The costs of a private cellular network vary based on coverage area, capacity requirements, underlying technology (4G vs 5G), and deployment model. For in-building private networks, it costs similar to enterprise WiFi, around 60 cents a square foot deployed. For outdoor private networks, the costs really depend on how open the area is, but can be as little as 5 cents per square foot. Assess your coverage area, capacity needs, and technology preferences carefully, and consult a qualified vendor to design a solution that meets both your budget and long-term goals.

4G LTE vs. 5G Private Networks: Which Should You Choose?

This depends on your needs and budget. 5G private networks are next-gen and provide better performance overall: faster data speeds (up to 500 Mbps on CBRS, which is twice the speed of 4G LTE on the same spectrum), lower latency (1 ms vs 30-50 ms in 4G LTE networks), and higher capacity for connected devices (double the number of used compared to 4G LTE). 5G also supports newer technologies like network slicing and edge computing. However, a 4G LTE network might suffice for your operations. Nevertheless, you should use equipment that is easily upgradeable to 5G in case it is required in the future.

• Speeds: Up to 10 Gbps (10–100x faster than 4G).
• Latency: As low as 1 millisecond.
• Capacity: Up to 1 million connected devices per sq. km.‍

‍Tip: Use 5G-upgradable equipment to future-proof your investment.

‍

Can Private Networks Integrate with Public Networks or WiFi?

Yes, hybrid deployments are possible. For example, an organisation can deploy a private network outdoors and use the existing Wi-Fi indoors allowing roaming between the two technologies. Or an organisation can leverage public cellular as a backup for its private network. This allows seamless integration while still giving organisations control over security of the network.

‍

What Spectrum Options Are Available for Private Networks?

Organizations can use licensed spectrum, shared spectrum (like CBRS), or unlicensed bands (Wi-Fi or LTE-U), depending on their location and requirements.

In the US, private networks are commonly deployed in the CBRS band. 

‍

What is CBRS (Band 48)?

Citizens Broadband Radio Service (CBRS) is a spectrum band (Band 48) that has revolutionised spectrum sharing in the US. It allows organizations to set up private LTE networks affordably through shared spectrum access that is lightly licensed.

CBRS enables affordable private LTE deployments with benefits like:

CBRS offers several pros over unlicensed spectrum such as improved security, enhanced mobility and range, and better capacity.

‍

How Long Does Private Network Deployment Take?

Deployment timelines typically range from a few months to a year, depending on the network's complexity and scale. Timelines ranges, depend on:

The deployment starts with the planning phase where the use cases, key performance indicators, the site, and types of private network are analyzed, and then moves to the implementation phase where the network is installed. 

‍

Who Benefits from Private Networks?

Sectors that require reliable outdoor coverage, handle sensitive data, run mission-critical applications, manage complex IoT systems, or require uninterrupted service are the primary beneficiaries of private networks. This manufacturing, warehousing, mining, oil and gas, logistics, healthcare, entertainment, event management, and construction sectors. Private networks are ideal for industries requiring:

This includes manufacturing, warehousing, mining, oil and gas, logistics, healthcare, entertainment, event management, and construction sectors.

‍

Is a Private Network Better Than WiFi?

Private networks and WiFi serve different purposes and have distinct advantages. While a private network might be better on some parameters such as coverage and latency, WiFi might be better suited for cost and indoor use cases. Both models often work side-by-side to provide a more comprehensive connectivity solution.

Best practice: Combine both for a comprehensive solution.

‍

‍What are the key Benefits of Private Networks?

Private networks offer enhanced long range outdoor coverage, better security control, greater reliability, lower costs over time, complete control over network resources, and tailored connectivity for specific applications.. Key benefits include: 

Private networks can be customized to meet specific operational demands, such as supporting advanced IoT systems, enabling real-time data processing with low latency, or integrating seamlessly with edge computing solutions. This level of customization and control makes private networks a strategic investment for industries seeking to drive innovation, improve productivity, and future-proof their connectivity infrastructure.

‍

What Maintenance Do Private Networks Require?

Regular maintenance includes software updates, performance optimization, security patches, and hardware maintenance are required.

‍

What is the Future of Private Networks?

The uptake of private networks is on the rise due to various factors such as the opening up of the CBRS band, availability of cheaper deployment models, etc. and existing private networks are gradually migrating from 4G LTE to 5G. Alongside this, advancements in 6G technology, edge computing, the growth of Internet of Things (IoT), AI, and better regulatory environment are also shaping the demand and benefits of private networks.

‍

How to Choose the Right Private Network Solution

Choosing the right private network solution involves identifying the primary use cases of the organisation, assessing Key Performance Indicators (KPIs) such as the number of connected devices, required bandwidth, data speeds, and latency, conducting a site survey, planning integration with existing IT systems in the building, determining whether to use 4G or 5G technology, identifying the type of infrastructure (on-premise, cloud, hybrid, etc.), estimating the budget and ROI, etc. Working with an experienced vendor could make this process smoother and more thorough.

Consider your specific requirements, budget, and long-term goals. Consulting with an experienced vendor is highly recommended.
