Private 5G networks for enterprises
In short: A private 5G network gives an organisation its own mobile network for a site such as a factory, port or campus. It can be fully owned or shared with an operator. It offers reliable mobility, coverage and SIM-based identity, but needs spectrum, new skills and the same careful security as any critical network.
What private 5G is
A private 5G network serves one organisation rather than the public. 3GPP calls these non-public networks (NPNs) and describes two main kinds: a standalone NPN, which runs independently of any public operator, and a public network integrated NPN, which is delivered with the help of a public network, for example as a dedicated slice. Typical sites include factories, warehouses, ports, mines, airports and large campuses.
| Model | Who runs what | Pros | Cons |
|---|---|---|---|
| Fully standalone | Enterprise owns RAN and core on site | Data stays local, full control, works if WAN is down | Highest cost and skill needs |
| Shared RAN, private core | Operator radio, enterprise core | Less hardware, local data handling | Dependent on operator coverage |
| Operator slice | Operator provides a dedicated slice | Fast to start, wide area | Less control, data leaves site |
| Managed service | Partner runs either model for you | Reduced in-house effort | Supplier dependence, contract risk |
Spectrum
Mobile networks need radio spectrum. Rules vary by country, so always check with the national regulator. Common routes are:
- Leasing from an operator that holds a national licence.
- Local or shared licences that some regulators offer for a specific site, for example in parts of the mid-band around 3.5 to 4 GHz in several European countries.
- Shared access schemes such as the Citizens Broadband Radio Service (CBRS) in the United States.
Private 5G or Wi-Fi?
Wi-Fi 6 and Wi-Fi 7 are excellent for offices and most indoor use, with very low device cost. Private 5G tends to win where devices move across large outdoor areas, where handover must be seamless (such as autonomous vehicles in a yard), or where predictable performance under load matters. Many organisations use both and connect them to the same enterprise network design.
Security and operations
- Identity: manage SIMs or eSIMs as credentials. Keep an inventory, revoke lost ones, and link each SIM to an asset owner.
- Segmentation: map devices into separate data networks, slices or VLANs after the UPF, and enforce firewall policy between them, as you would for IoT segmentation.
- Protect the core: the core is software on servers. Harden hosts, restrict management access, patch regularly and back up configuration.
- Integrate with OT: in factories, align with IEC 62443 zones and conduits and involve operational technology engineers early.
- Monitor: send core and RAN logs to your SIEM, and watch for rogue radios, unknown SIMs and abnormal traffic.
- Plan skills and support: radio planning, core operations and vendor support contracts are new areas for most IT teams.
Tip: run a pilot in one area with clear success measures, such as coverage, latency and device availability, before committing to a site-wide roll-out.
Practice
What does 3GPP call a private mobile network that runs independently of public operators?
Name one situation where private 5G may be better than Wi-Fi.
Why should SIMs be managed like credentials?
Key takeaways
- Private 5G is a mobile network for one organisation; 3GPP calls it a non-public network.
- Models range from fully owned to an operator-hosted slice.
- Spectrum rules vary by country; check the regulator.
- Use private 5G where mobility, coverage and predictability matter; Wi-Fi elsewhere.
- Secure SIMs, segment traffic, harden the core and monitor it.
