Private 5G vs LTE Network Comparison: Speed, Latency, Cost and Use Cases
Private 5G slashes latency from 30–50ms to less than 10ms, with optimised setups achieving as low as 1ms. This improvement makes real-time control possible, enabling industrial control loops that were previously out of reach with older technologies.
Bandwidth gets a substantial boost as well. While LTE typically delivers speeds in the range of tens to hundreds of Mbps, 5G offers multi-gigabit throughput. This kind of capacity supports applications like high-definition video analytics for AI-driven quality control and digital twin technologies.
Another standout feature is network slicing, which allows a single network to be divided into virtual networks, each tailored for specific tasks. For instance, one slice can be optimised for ultra-low latency robotics control, while another can handle high-bandwidth video surveillance.
These advancements in speed and capacity lay the groundwork for large-scale, high-density deployments.
Building on its performance edge, Private 5G is designed to scale for a wide range of industrial needs. It operates across three frequency bands:
This flexibility makes it possible to connect a massive number of devices. For example, in large manufacturing or logistics operations, 5G can support thousands of IoT devices and sensors within a single facility. Real-world applications include the Ningbo Zhoushan Port Authority, which uses 5G for remote monitoring and video surveillance of gantry cranes, and Sandvik, which implemented it in mines to power Automated Guided Vehicles.
Modern deployment models make scaling even more practical. Subscription-based offerings, like those from Firecell, allow businesses to expand their infrastructure as needed without heavy upfront investment. For instance, Firecell charges £86 per 1,000m² per month (approximately €99), with initial infrastructure costs covered by the provider for spaces exceeding 10,000m².
Security is a top priority for industrial applications, and Private 5G delivers robust, industrial-grade protections. Unlike Wi-Fi, which relies on credential-based authentication, 5G requires a physical or electronic SIM card for device access, significantly reducing the risk of unauthorised entry. As Cisco highlights:
"Private 5G communications are encrypted, and an appropriate SIM card must be present in the endpoint device to enable access."
Private 5G also includes native end-to-end encryption, ensuring that all communication between devices and the core network remains confidential and secure. For maximum protection, organisations can deploy standalone Non-Public Networks (NPN Model C), which physically separate industrial data from public cellular traffic, ensuring complete data sovereignty.
Additionally, the technology supports zero-trust security frameworks, a critical feature for safeguarding sensitive assets. Ericsson underscores this point:
"Private networks are expected to provide full end-to-end security to ensure information, infrastructure and people are protected from threats."
Given its advanced capabilities, Private 5G comes with a higher price tag compared to LTE. However, subscription models can help offset the initial costs. For example, Firecell offers a starter fee of £390 per 1,000m² (around €450) and monthly subscriptions of £86 per 1,000m² (approximately €99).
For organisations planning to adopt cutting-edge technologies like automation, AI, or augmented reality in the next 3–5 years, investing in 5G now ensures they have the infrastructure to support these advancements.
Private LTE has been a trusted industrial standard for over a decade, delivering secure connectivity and sufficient bandwidth for applications like mobile asset tracking, warehouse vehicle management, and voice communications. Its bandwidth typically ranges from tens to hundreds of Mbps, which is suitable for these tasks. However, it falls short when it comes to supporting the multi-gigabit requirements of emerging technologies such as high-definition video analytics and digital twins. As Cisco explains:
"Private LTE (4G) networks have been in use for more than 10 years, providing secure connectivity in use cases where coverage and reliability are needed."
One of LTE’s standout features is its ability to maintain reliable connectivity across large areas, making it a better option than Wi-Fi in such scenarios. For example, large warehouses, remote mining sites, and sprawling logistics centres benefit from LTE’s superior mobility and reliability. Unlike Wi-Fi, which can suffer from lags or dropouts during handoffs, LTE ensures consistent performance, making it an ideal choice for wide-area scalability.
Private LTE is particularly effective in providing wide-area coverage for industries like utilities, airports, and mining. Using low-band spectrum (below 1 GHz), it can cover hundreds of square miles, while mid-band spectrum (Sub-6 GHz) typically offers coverage spanning several miles. While this makes LTE a good fit for general enterprise needs, it does have limitations, particularly when it comes to supporting environments with a high density of IoT devices.
Security is one of the key strengths of Private LTE. It uses SIM-based authentication to tightly control network access, ensuring that only authorised devices can connect. All communications are encrypted, which adds an extra layer of protection – especially crucial in industrial environments or remote locations where data integrity is critical.
When it comes to cost, Private LTE is generally less expensive to deploy than 5G, though it does cost more than Wi-Fi due to the complexity of its cellular components, originally designed for public networks. However, the market is evolving, with subscription-based models becoming more common. This shift lowers the financial barrier for small and medium-sized enterprises (SMEs) looking to adopt this technology.
For organisations assessing their current and future needs, LTE offers a cost-effective solution for reliable coverage and mobility. However, facilities planning to adopt high-density sensor networks or real-time robotic control may find 5G’s capabilities more aligned with their long-term goals. While LTE delivers proven reliability at a lower upfront cost, its features are distinct from the advanced possibilities that 5G brings to the table.

The cost of setting up private LTE and private 5G networks can vary quite a bit, mainly due to differences in hardware, spectrum availability, and ongoing operational needs.
Private LTE tends to have lower upfront costs (CAPEX). This is largely because the technology is well-established, with mature hardware that’s readily available. On top of that, LTE spectrum is often more affordable and, in some cases, can be accessed through unlicensed bands, making it a more budget-friendly choice at the start. On the other hand, deploying private 5G comes with higher initial costs. This is due to the need for newer hardware, like advanced high-frequency radios and denser antenna infrastructure, along with access to mid-band spectrum, which is usually more expensive.
When it comes to operational costs (OPEX), LTE has the advantage of being around for years, so many enterprises already have the expertise and maintenance systems in place to keep costs manageable. Private 5G, while offering better performance – such as ultra-low latency and the ability to handle more devices – can lead to higher energy costs and may demand specialised skills for fine-tuning and maintenance. That said, newer pricing models, like subscription-based private 5G services, are emerging. These allow businesses to spread the costs over time, easing the burden of a large upfront investment.
Yes, combining private 5G and LTE networks into a hybrid setup is entirely possible. This approach lets organisations take advantage of the high performance and speed of 5G while benefiting from LTE’s extensive coverage and proven reliability.
That said, hybrid deployments aren’t without their challenges. They might introduce slightly higher latency or pose some security concerns. To make this work effectively, meticulous planning and management are crucial. This ensures the network aligns with your specific connectivity requirements while addressing these potential trade-offs.
