Private 5G networks are transforming industries like manufacturing, logistics, and energy by solving connectivity challenges and delivering measurable returns. For example, 87% of enterprises report ROI within 12 months, with benefits ranging from reduced downtime to operational savings. However, deploying private 5G requires a clear understanding of costs and benefits to justify the investment.
By identifying use cases, running pilots, and calculating ROI using clear metrics like downtime reduction and maintenance savings, organisations can make informed decisions. This guide breaks down the framework to help you assess the financial impact of private 5G for your operations.
Private 5G Network ROI: Key Costs, Benefits, and Returns
The initial investment for private 5G varies greatly depending on the size and complexity of the deployment. For instance, enterprise-level installations can range from approximately £200,000 to £800,000. Smaller setups, such as a warehouse, might cost between £40,000 and £80,000. Multi-campus projects, however, can significantly exceed these figures. For a typical manufacturing facility spanning 250,000 sq. ft. (around 23,000 m²), roughly 20 5G radios are needed to ensure reliable coverage – this is far fewer than the 50 to 80 access points required for older technologies like Wi-Fi.
A major factor influencing cost is the core network architecture. Cloud-based 5G core networks can reduce infrastructure costs by up to 40% compared to on-premises setups. Small cells, essential for 5G, typically cost between £8,000 and £40,000 per site. Indoor access points often start at around £17,000, while outdoor units can be priced at approximately £46,000. Additionally, backhaul infrastructure, mainly fibre optic cabling, accounts for 15% to 30% of the total deployment cost. Installation costs for fibre vary widely, ranging between £20,000 and £80,000 per kilometre, depending on terrain and local regulations.
Spectrum access is another important variable. In the UK, organisations can use local or shared licensed spectrum, with costs dependent on specific licensing arrangements. To ensure reliable coverage and avoid performance issues later, professional RF studies and site surveys are crucial.
Beyond hardware, integration and workforce training also play a significant role in the overall costs.
Integration costs go beyond just hardware setup – they also include ensuring system compatibility and preparing the workforce. The deployment process typically begins with business engagement and test plan development, followed by network design, installation, and training.
Developing a business case to outline requirements, use cases, and potential savings is an important step, with services costing around £1,350 per unit. Edge computing integration is a key feature in the majority (94%) of successful deployments, as it enables real-time data processing. While this adds to the upfront costs, it is essential for unlocking the operational benefits of private 5G. Labour costs during the training phase – including activities like validating the test plan and onboarding employees – represent another distinct expense. However, the reduced number of access points required for 5G helps lower installation, labour, and cabling costs.
Many vendors offer software-as-a-service (SaaS) models with three- or five-year subscription plans. This allows organisations to shift integration costs from a capital expense to a more manageable operational expense model.
Once setup and integration are complete, the long-term financial impact comes from operational and maintenance costs.
Ongoing operational expenses typically range from 15% to 20% of the initial capital expenditure each year. These costs cover essentials like 24/7 network monitoring, software updates, security patches, and support services. Energy costs are another consideration, as 5G networks consume three to four times more energy than 4G systems due to the higher number of base stations and increased real-time processing demands.
Interestingly, 86% of industrial enterprises report lower ongoing costs after deploying private 5G, with 60% achieving at least 11% annual operational savings. These savings are largely due to unified core management software, which simplifies network oversight compared to managing numerous Wi-Fi devices. Additionally, fewer access points mean reduced physical maintenance and labour costs over time.
Private 5G also eliminates the recurring expense of recabling when production lines or facility layouts change – a common issue with wired Ethernet. Moreover, IoT sensor integration enables predictive maintenance, shifting from reactive to proactive approaches. This can reduce unplanned downtime by 25% to 30%. Over a five-year period, Wi-Fi can end up costing around 22% more per square metre than private 5G when total ownership costs are considered.
Private 5G networks bring a game-changing advantage by enabling immediate data acknowledgement, eliminating the multi-second delays often seen with Wi‑Fi. This instant responsiveness allows workers to maintain peak productivity without waiting for network lag.
Devices like Autonomous Mobile Robots (AMRs) and Automated Guided Vehicles (AGVs) benefit immensely from 5G’s seamless signal handover. Unlike Wi‑Fi, which can cause connection drops during handovers, 5G allows these vehicles to operate at speeds up to 30% faster. For manufacturers managing fleets of AGVs across sprawling facilities, this speed boost directly translates into higher throughput and faster order processing [2, 15].
Cloud-based 5G also revolutionises quality control. Real-time AI inspections powered by 5G can increase testing capacity by 25%. For example, IKD, a Chinese automotive supplier, experienced a 10% rise in overall product yield in 2025 after swapping out 6 miles of Ethernet cables for a private 5G network connecting 600 machines. This wireless setup not only enhanced flexibility in production line reconfiguration but also eliminated the physical limitations of fixed Ethernet connections.
Beyond speed and flexibility, private 5G’s real-time data capabilities pave the way for proactive maintenance, helping reduce downtime and optimise operations.
Private 5G doesn’t just boost productivity – it also tackles one of the most expensive problems in industrial settings: unplanned downtime. In high-stakes manufacturing environments, downtime can cost over £80,000 per hour. With private 5G, continuous monitoring of critical metrics like temperature, vibration, and pressure enables predictive maintenance, cutting unplanned downtime by 25–30%.
Take Newmont‘s Cadia gold-copper mine in Australia, for instance. By deploying private 5G in 2025, the mine enabled 24/7 autonomous operation of its dozer fleet across a 2.5-kilometre tailings area. This upgrade eliminated up to six hours of downtime per shift caused by unreliable Wi‑Fi connections. Such recovery of lost time can lead to significant annual savings.
Switching to predictive maintenance also reduces emergency repair costs and extends the lifespan of machinery. Tesla’s Gigafactory Berlin-Brandenburg provides a compelling example. After implementing private 5G in 2025, the factory resolved up to 90% of "overcycle" issues in its General Assembly shop, significantly boosting production throughput.
In manufacturing, private 5G supports the deployment of up to 1 million IoT devices per square kilometre – ten times more than 4G can handle. This capability enables comprehensive monitoring of equipment, environmental conditions, and quality. Additionally, eliminating Ethernet cabling, which costs around £180 per drop, can save factories hundreds of thousands of pounds annually.
Logistics operations also see major improvements. Enhanced performance of AGVs and AMRs under 5G networks has been transformative. For example, CJ Logistics achieved a 20% productivity increase and cut infrastructure costs by 15% compared to a Wi‑Fi solution. Unlike Wi‑Fi, which often struggles in environments filled with metal structures and constant vehicle movement, 5G delivers consistent, mission-critical performance.
In the energy sector, private 5G boosts safety and efficiency by enabling connected workers in hazardous environments and facilitating remote asset monitoring. Risun Group in China saw a 20% rise in production efficiency and a 30% reduction in labour costs after transitioning to private 5G in 2025. The network also provided coverage in previously inaccessible hazardous areas, reducing the need for personnel in dangerous zones while maintaining full operational control.
"It is important for everyone involved in promoting Industry 4.0 in manufacturing settings… to recognise the cost-saving benefits of 5G and private cellular, with an eye towards flexibility with its use."

Across industries, the numbers speak for themselves: 87% of industrial enterprises report measurable ROI within 12 months of deploying private 5G networks. These benefits not only make private 5G a sound financial decision but also establish it as a powerful tool for transforming operations across sectors.
Start by identifying where private 5G excels compared to Wi-Fi. Look at scenarios needing high mobility, broad coverage, or operations in challenging environments with significant steel and concrete barriers. Examples include autonomous mobile robots, real-time quality control cameras, and connected workers in hazardous areas. These applications often require the consistent performance that Wi-Fi struggles to deliver.
A single 5G network can handle multiple use cases, cutting costs by eliminating the need for separate systems. For instance, instead of deploying individual networks for AGVs, quality control, and worker connectivity, a private 5G network spreads the investment across all these applications, improving the return on investment.
Establish baseline metrics like downtime, processing times, maintenance costs, and safety expenses before deployment. These benchmarks are essential for measuring improvement. For example, Newmont’s Cadia mine faced six hours of downtime per shift due to unreliable connectivity before adopting private 5G. This downtime figure became the baseline for calculating savings. With clear metrics in place, you can apply a standard ROI formula and determine payback periods.
The formula for ROI is straightforward: (Total Benefits − Total Costs) ÷ Total Costs × 100%. Total costs include infrastructure (e.g., access points, spectrum licensing, and edge computing hardware), integration expenses (such as installation labour and security measures), and ongoing operational costs. On the benefits side, consider productivity improvements, reduced downtime, maintenance savings, and avoided infrastructure costs.
For the payback period, use this formula: Total Investment ÷ Annual Net Savings. Interestingly, 87% of industrial enterprises report achieving measurable ROI within 12 months of deploying private 5G. A typical timeline includes 1–3 months for needs assessment and pilot planning, followed by 3–6 months for pilot deployment and validation. When calculating the total cost of ownership, don’t forget factors like energy savings (up to 20%), lower re-cabling expenses during facility changes, and reduced device management costs over five years.
Additionally, 60% of enterprises report at least 11% annual OPEX savings post-deployment. In manufacturing, where downtime can exceed £80,000 per hour, even minor uptime improvements yield significant returns. For instance, IKD cut cable maintenance costs to nearly zero and boosted product yield by 10% after replacing six miles of cables with a private 5G network. Piloting the solution helps refine these assumptions and validate projected savings.
Before committing to a full-scale rollout, run small pilot projects to test your ROI calculations. A well-structured pilot includes five stages: business engagement, test plan development, network design, installation, and validation against the test plan. Set clear success criteria, such as acceptable packet loss rates, connection timeout thresholds, and signal handover performance, and measure results against these benchmarks.
Focus on "lighthouse" projects that provide immediate business value and demonstrate capabilities beyond Wi-Fi. Pilots turn theoretical projections into reliable forecasts by validating assumptions about coverage, reliability, and productivity gains. The data gathered during these pilots builds confidence in the larger business case.
"The fastest way to move beyond trials and drive adoption by businesses is to apply 5G to use cases which surpass the capabilities of Wi‑Fi." – Ericsson
Expanding on the earlier ROI framework, let’s look at how industries are seeing measurable benefits and cost savings. For instance, Tesla’s Gigafactory Texas showcases how private 5G can address challenges like AGV stoppages caused by unstable Wi‑Fi. In fact, Tier‑1 automotive suppliers could achieve a 28× ROI over five years by leveraging similar technology.
Additionally, cloud-based quality control powered by private 5G can boost testing capacity by 25%. On top of that, switching to 5G could save an average factory hundreds of thousands of pounds annually by eliminating the need for extensive Ethernet cabling.
Private 5G isn’t just transforming manufacturing; it’s also delivering value in energy and logistics. For logistics operations, replacing extensive Wi‑Fi infrastructure with fewer 5G small cells can lead to investment savings of around 15%.
In the energy sector, private 5G enhances both safety and efficiency. It enables connected workers to operate in hazardous environments and supports remote asset monitoring. These advancements reduce the need for personnel to enter dangerous zones while still ensuring full operational control. The result? Noticeable gains in productivity and cost management.
Private 5G is no longer a concept with uncertain returns – it’s delivering tangible benefits. A striking 87% of enterprises report measurable returns within just 12 months, while 81% find that their initial investment costs are lower than traditional alternatives. These numbers highlight how, with the right evaluation, private 5G offers quick payback while also cutting long-term operational costs.
Armed with a detailed cost-benefit analysis, you can now assess the financial impact of private 5G in your specific context. The key is to take a systematic, data-driven approach. Start by identifying your primary use case – whether it’s connecting automated guided vehicles (AGVs) in manufacturing, enabling remote inspections in the energy sector, or supporting high-speed scanning in logistics. Then, use the ROI calculator provided in this guide, which considers factors like facility size, device density, and downtime costs. Before scaling up, validate your assumptions with a pilot project to ensure accuracy.
As one industry leader puts it:
"Private 5G isn’t an expensive experiment anymore. It’s an effective financial tool that delivers payback before you finish your first financial year."
The real game-changer comes when private 5G is combined with on-premises edge computing. This pairing enables AI-driven applications that shift maintenance strategies from reactive to predictive. Notably, 94% of successful deployments include edge computing, underscoring its importance in achieving meaningful financial outcomes.
With private networks expected to drive £43 billion in business transformations by 2030, the real question isn’t whether to invest – it’s how quickly you can craft a strong business case. Use the frameworks in this guide to systematically evaluate costs and benefits, aligning your investment decisions with your strategic objectives. A well-structured ROI framework ensures your investments deliver both immediate and long-term value.
When setting up a private 5G network, there are several important costs to keep in mind. These include infrastructure expenses, which cover everything from hardware to site preparation, as well as ongoing maintenance to keep the network running efficiently. Another key consideration is integration costs, ensuring the network works seamlessly with your existing systems.
Don’t overlook spectrum licensing fees either – these can vary widely based on your location and how you plan to use the network. Finally, the scale of coverage required to meet your organisation’s needs will significantly influence the overall investment.
Taking the time to assess these factors will give you a better picture of the financial commitment involved, helping you make decisions that align with your organisation’s objectives.
Private 5G offers long-term cost savings by improving operational efficiency, increasing automation, and reducing downtime. These advantages often lead to a quicker return on investment (ROI), with many businesses seeing results in under a year.
On the other hand, Wi-Fi, though commonly used, functions as a "best effort" technology. It often falls short in reliability, scalability, and cost efficiency, particularly in demanding industrial settings. This makes private 5G a more practical option for industries such as manufacturing, logistics, and energy.
Validating the return on investment (ROI) assumptions before rolling out a private 5G network requires careful planning and analysis. Start by pinpointing your specific business objectives – whether it’s improving productivity, reducing downtime, or advancing automation. Assign measurable values to these goals so you can gauge their potential impact on your operations.
Next, take a close look at the costs involved. This includes infrastructure setup, ongoing maintenance, and integration expenses. Establishing a clear financial baseline is essential to understanding the overall investment. Running a small-scale pilot or implementing the network in phases can offer practical insights and allow you to fine-tune your assumptions based on actual results.
To ensure your projections are grounded, compare your data against industry benchmarks and case studies. This step helps you validate your expectations and minimises the risk of unforeseen costs or surprises when scaling up the deployment. A methodical approach like this ensures you’re making well-informed decisions every step of the way.
