Private wireless networks have moved beyond small 5G experiments. Manufacturers, warehouses, ports, mines, airports, utilities, and large campuses now use private LTE and private 5G for jobs where ordinary Wi-Fi or public cellular cannot always provide the required mobility, coverage, or control.
Berg Insight estimates that 6,500 production private LTE/5G networks were deployed worldwide by the end of 2025, up from 4,700 a year earlier. It valued the private LTE/5G solutions market at about $2.4 billion in 2025 and forecasts it could reach $12 billion by 2030. The research firm also counted close to 60 companies supplying RAN or mobile-core technology for private networks.
That growth creates a new problem for buyers: choosing among dozens of private wireless network vendors that sell very different products. Some provide complete radio and 5G core systems. Others focus on enterprise-friendly management, industrial automation, Open RAN, or fully managed private 5G.
This guide compares 10 important vendors in 2026. It also explains how private networks work, what they cost, how to build one, and when private 5G makes more sense than simply upgrading Wi-Fi.

What Is a Private Wireless Network?
A private wireless network is a wireless network reserved for one organization rather than the general public. The term can describe a private Wi-Fi LAN, but in enterprise telecom it usually refers to a dedicated private LTE or private 5G network.
Think of public cellular as a public highway. Thousands of users share the infrastructure. A private cellular network works more like a controlled road inside a factory, port, mine, university, or business campus. The organization controls who enters, what applications receive priority, where data travels, and how the radio coverage is designed.
Ericsson defines private cellular as a dedicated 4G LTE or 5G network with infrastructure serving a specific organization within a defined geographic area. Typical components include radios or small cells, a cellular core, SIM or eSIM credentials, user devices, backhaul, and management software.
Private LTE vs. Private 5G
Private LTE remains useful for scanners, industrial tablets, voice, cameras, basic IoT, and equipment that does not require advanced 5G capabilities. It also has a mature device ecosystem.
Private 5G adds more capacity and creates a better foundation for applications such as autonomous mobile robots, machine vision, high-bandwidth video, edge AI, and advanced industrial automation. Many current solutions support both LTE and 5G, allowing businesses to migrate instead of replacing everything at once.
What Are Examples of Private Networks?
Common examples include a home LAN, corporate Wi-Fi network, VLAN, VPN, private cloud network, private LTE network, and private 5G network. This article focuses mainly on private LTE and 5G because that is where today’s private wireless vendor market is expanding fastest.
Why Businesses Use Private Wireless Networks
Most companies do not deploy private 5G simply because it is newer than Wi-Fi. They deploy it when a real operational problem justifies the extra cost and complexity.
A conventional office with laptops, printers, phones, and meeting rooms will usually get better value from modern enterprise Wi-Fi. Private cellular becomes more interesting when machines or people must stay connected while moving across a large site, when outdoor coverage matters, or when critical applications need tightly controlled wireless capacity.
Ericsson notes that private cellular can provide broader radio coverage, mobility-oriented handoffs, dedicated capacity, SIM-based authentication, and control over service policies. HPE also positions private 5G as a complement to Wi-Fi for wide-area, high-speed mobility and latency-sensitive applications rather than as a universal Wi-Fi replacement.
| Problem | Common Cause | Business Impact |
|---|---|---|
| Wireless dead zones | Large buildings, metal structures, outdoor areas | Lost connectivity and downtime |
| Robot or vehicle disconnects | Poor roaming between Wi-Fi APs | Interrupted automation |
| Unpredictable performance | Shared radio capacity or interference | Delayed applications |
| Outdoor coverage gaps | Limited Wi-Fi range | More infrastructure required |
| Weak device identity | Poor access control | Security exposure |
| Public-network dependence | Carrier-controlled infrastructure | Less operational control |
| Difficult expansion | Separate network tools and systems | Higher support costs |
Here is what matters: private 5G solves particular networking problems. It should not become the problem itself.
How We Evaluated Private Wireless Network Vendors
A vendor comparison should look beyond 5G speed claims. A usable enterprise solution needs radios, a mobile core, device authentication, spectrum support, monitoring, integration with existing IT and often edge computing.
We therefore considered each vendor’s 4G/5G support, indoor and outdoor options, core architecture, SIM and eSIM management, deployment model, enterprise integration, industrial features, security controls, management experience, global reach, and ability to support real production networks.
Management deserves special attention. Telecom networks traditionally require skills that a normal IT team may not have. Cisco and HPE now emphasize simplified private 5G operations that fit more naturally into enterprise networking workflows. Cisco, for example, describes its Private 5G service as a way to provision, manage, and troubleshoot 5G and IoT without forcing organizations to build a carrier-style operations team.
That shift may determine which private wireless vendors win enterprise projects. The best technology is less useful when the customer’s team cannot operate it confidently.
Private Wireless Network Vendors Compared
| Vendor | Main Offering | Best Fit | Key Strength |
|---|---|---|---|
| Ericsson | Ericsson Private 5G | Industrial enterprises | Full-stack industrial private 4G/5G |
| Nokia | Digital Automation Cloud | Industrial campuses | Large deployment base and edge platform |
| HPE Aruba Networking | HPE Aruba Private 5G | Enterprise IT teams | Wi-Fi-like management |
| Celona | Celona 5G LAN | Warehouses and enterprises | LAN-style private cellular |
| Siemens | Industrial Private 5G | Manufacturing | OT and automation integration |
| Samsung Networks | Private Network Solutions | Large enterprise deployments | End-to-end RAN, core, management |
| Cisco | Cisco Private 5G | Existing Cisco environments | Enterprise integration and operations |
| Mavenir | MAVedge Private Networks | Flexible architectures | Cloud-native and Open RAN approach |
| Verizon Business | Private 5G Network | Managed deployments | Design, deployment, ongoing management |
| NTT DATA | Managed Private 5G | Global enterprises | Integration, managed services, edge AI |
1. Ericsson
Best for: Large industrial and mission-critical sites
Ericsson remains one of the most complete private cellular infrastructure vendors. Ericsson Private 5G supports both 4G and 5G, indoor and outdoor deployment, local data handling, cloud-based network management, and integration with IT and operational technology systems through APIs. The company offers different deployment sizes so organizations can begin with a limited site and expand later.
Its strongest fit is not a normal office. Ericsson makes more sense in factories, ports, mines, utilities, warehouses, airports, and other environments where network failures can disrupt physical operations.
A useful real-world example comes from cement producer CIMPOR. In Portugal, Vodafone and Ericsson deployed private 5G across three cement plants to support industrial applications in challenging environments with dust, vibration, metal structures, autonomous systems, and thousands of sensors.
Ericsson also expanded its partnership with Verizon Business in June 2026 so multinational customers can deploy Ericsson Private 5G through Verizon beyond the United States.
Techoble take: Put Ericsson high on the shortlist when coverage, industrial reliability, mobility, and global deployment capability matter more than finding the lowest-cost entry point.
2. Nokia
Best for: Established industrial private wireless environments
Nokia has one of the largest installed bases in private cellular. Its Digital Automation Cloud, commonly called Nokia DAC, combines 4.9G/LTE and 5G private wireless with industrial edge computing and applications. Nokia also offers smaller configurations such as DAC PW Compact for small and medium industrial locations.
Berg Insight reported that Nokia had roughly 960 customers and more than 2,000 private network deployments at the end of 2025, making it the largest of the major RAN suppliers by private-network deployment count in that research.
There is an important 2026 procurement issue, however. In July 2026 Nokia classified its Enterprise Campus Edge business as a discontinued operation held for sale, saying a sale was highly probable.
That does not erase Nokia’s technology, customers, or installed systems. It does mean a buyer considering a new long-term deployment should ask direct questions about ownership, future support, product roadmaps, warranties, software updates, and migration commitments.
Techoble take: Nokia remains highly relevant, especially for existing deployments, but new buyers should make product-roadmap due diligence part of the purchasing process.
3. HPE Aruba Networking
Best for: IT teams that want private 5G to feel more like enterprise Wi-Fi
HPE Aruba Networking takes a different approach. Instead of expecting enterprise IT teams to operate private cellular like telecom engineers, HPE focuses on making deployment and administration feel familiar.
HPE Aruba Networking Private 5G provides an end-to-end solution with cellular core software and enterprise-oriented management. HPE says administrators can configure and operate private 5G in a way similar to Wi-Fi, with automated configuration and zero-touch provisioning.
Its current core supports both 4G EPC and 5G Core functions. HPE documents on-premises, hybrid, and cloud deployment options, which helps organizations match the architecture to data sovereignty and operational requirements.
This option becomes especially attractive when a company already uses Aruba Wi-Fi or wants one enterprise networking strategy rather than separate Wi-Fi and cellular teams.
Techoble take: HPE Aruba is one of the most practical choices for businesses that understand enterprise networking but do not want to become mobile operators.
4. Celona
Best for: Enterprise-friendly private 5G and warehouse environments
Celona built its reputation around the idea of a 5G LAN. The goal is to make private cellular behave more like familiar enterprise network infrastructure.
Its platform combines indoor and outdoor access points, a converged LTE/5G core, SIM and eSIM support, policy controls, and cloud-based orchestration. Current Celona documentation describes its Edge and Orchestrator components working across an organization’s existing LAN and WAN for provisioning, configuration, reporting, and troubleshooting.
This model fits warehouses, distribution centers, manufacturing floors, outdoor yards, and environments where scanners or moving machines struggle with ordinary Wi-Fi roaming.
Celona is also useful when organizations want private wireless to coexist with Wi-Fi instead of replacing it. That is an increasingly important design principle in 2026.
Techoble take: Consider Celona when your network team wants private cellular without adopting the operating model of a traditional telecom carrier.
5. Siemens
Best for: Industrial automation and manufacturing
Siemens approaches private 5G from the factory floor rather than from a traditional carrier network.
Its industrial private 5G infrastructure targets manufacturing, pharmaceuticals, food and beverage, intralogistics, heavy industry, and other operational technology environments. In April 2026, Siemens announced expansion of its private 5G infrastructure to 15 countries across Europe and the Americas, including a new radio for the U.S. CBRS band. It also added edge-runtime capabilities to 5G routers so applications can run closer to industrial devices.
That is important because connectivity alone rarely completes an Industry 4.0 project. Private 5G must work with industrial switching, automation systems, diagnostics, cybersecurity, production applications, and edge processing.
Siemens already has deep relationships with industrial engineering teams, which can simplify those integration conversations.
Techoble take: A manufacturer using Siemens automation should evaluate Siemens private 5G before treating wireless as a separate telecom purchase.
6. Samsung Networks
Best for: Businesses seeking an end-to-end cellular infrastructure supplier
Samsung Networks provides the main building blocks of a private cellular network rather than only one software layer. Its private-network portfolio includes radios, baseband equipment, core functions, and a dedicated private network management system.
Samsung’s Compact Core is particularly interesting for enterprise deployments. It can support both 4G and 5G functions and can operate on-premises when an organization wants traffic processing and core functions inside its own environment. Samsung also supports remote management and cloud-based deployment models.
The portfolio makes sense for industrial and large-enterprise environments where buyers want the RAN and core to come from a company with substantial commercial cellular experience.
Techoble take: Samsung is worth comparing with Ericsson and other end-to-end suppliers when the project requires a complete cellular stack rather than a small overlay network.
7. Cisco
Best for: Enterprises already invested in Cisco networking
Cisco’s biggest advantage is not simply 5G radio technology. It is enterprise networking context.
Cisco Private 5G is designed as a service that reduces the operational complexity of building and managing private cellular. Cisco includes assessment and site-survey support while positioning the platform around simplified provisioning, management, troubleshooting, IoT integration, and enterprise-grade support.
This matters for companies that already depend on Cisco for switching, routing, security, identity, or network policy. Private 5G can then become another access technology connected to existing enterprise systems instead of an isolated telecom island.
Expert take: Cisco’s approach reflects an important industry shift. Successful private 5G projects increasingly depend on IT integration and operational simplicity, not just radio performance.
Techoble take: Cisco deserves special consideration when the company already has a Cisco-heavy network and wants private 5G integrated with familiar tools and processes.
8. Mavenir
Best for: Cloud-native and open private network architectures
Mavenir appeals to buyers that want more architectural flexibility.
Its private network portfolio supports LTE and 5G, Open RAN, CBRS, cloud-native mobile cores, SIM and eSIM management, edge computing, and several deployment models. Businesses can deploy components on-premises, in cloud environments, or through hybrid architectures.
Mavenir emphasizes software-centric infrastructure rather than tightly closed proprietary stacks. That can matter to organizations or system integrators trying to avoid excessive dependence on one hardware supplier.
The tradeoff is that open architectures can require careful integration and testing. Flexibility provides value only when the organization or integration partner has the skills to manage it.
Techoble take: Mavenir belongs on the shortlist for advanced buyers who value cloud-native software, Open RAN, and deployment flexibility.
9. Verizon Business
Best for: Businesses that want private 5G as a managed service
Not every organization wants to purchase radios, cores, spectrum services, SIM platforms, and management tools separately. Verizon Business addresses that buyer.
Its Private 5G Network service includes help with architecture, deployment, spectrum options, ongoing management, and an on-site network dashboard. Verizon targets manufacturing, transportation, healthcare, utilities, mining, retail, and other large enterprise environments.
One customer example is GSM Outdoors, where Verizon reports a 66% productivity improvement after a private wireless deployment at a 500,000-square-foot warehouse. That figure comes from Verizon’s customer story, so buyers should treat it as a specific case rather than a guaranteed outcome.
Techoble take: Verizon becomes attractive when the main business question is not Which 5G core should we buy? but Who can design and operate this network for us?
10. NTT DATA
Best for: Global enterprises and managed private 5G
NTT DATA fits multinational organizations that need system integration and managed operations across several countries.
In February 2026, NTT DATA and Ericsson announced a multi-year private 5G partnership. The model combines Ericsson’s Private 5G and edge platforms with NTT DATA’s networking services, IT/OT security expertise, managed services, and edge AI. Their initial focus includes manufacturing, mining, ports, airports, transportation, energy, and smart-city environments.
This points to where private wireless is heading. Businesses increasingly want more than connectivity. They want a repeatable platform that connects equipment, processes data locally, feeds AI applications, and can be reproduced across many sites.
Techoble take: NTT DATA is most compelling when an enterprise wants an integrator and managed-service partner rather than simply buying cellular infrastructure.
Which Private Wireless Vendor Is Best?
There is no single winner because these vendors solve different versions of the private-network problem.
For large industrial private 5G, start with Ericsson. For manufacturing environments where automation integration dominates the project, examine Siemens. For IT teams that want private cellular to resemble normal enterprise networking, HPE Aruba Networking, Celona, and Cisco deserve close attention.
Businesses wanting an open, software-centric architecture should investigate Mavenir. Companies that prefer someone else to operate the network should compare Verizon Business and NTT DATA.
Nokia remains significant because of its installed base and industrial platform, but its 2026 Enterprise Campus Edge disposal process means new buyers should confirm the future product and support structure before signing a long contract.
The right shortlist should come from your use case first and the vendor name second.
How Much Does a Private 5G Network Cost?
There is no reliable single price for a private 5G network. A small indoor proof of concept and a multi-building industrial deployment are completely different projects.
The main costs come from the radio access network, cellular core, spectrum, site survey, installation, backhaul, SIM or eSIM provisioning, compatible devices, edge computing, IT/OT integration, software subscriptions, cybersecurity, support, and ongoing network operations.
Public pricing examples show how wide the range can be. One UK private-network supplier currently lists indoor small-cell plus 5G-core bundles around £14,000 to £18,500 before a full enterprise deployment is designed. Another 2026 UK provider estimates traditional projects from around £50,000 for a single-site pilot to £500,000 or more for large industrial deployments. These are vendor-supplied examples, not universal industry price standards.
Managed-service pricing works differently. Providers may finance the infrastructure and charge monthly fees based on coverage, radios, devices, or capacity instead of requiring the customer to purchase the complete network upfront.
For budgeting, a useful rule is:
Small trial or lab: tens of thousands
Production factory or warehouse: often tens to hundreds of thousands
Large multi-site industrial network: potentially hundreds of thousands to millions
Treat those as planning bands only. A proper quote needs an RF survey and application requirements.
How Do I Create a Private Wireless Network?
Building private 5G should follow the business requirement, not the hardware catalog.
The practical flow is:
Use case → Site survey → Spectrum → Architecture → Vendor → Radios and core → Devices and SIMs → IT/OT integration → Security → Testing → Monitoring
1. Define the Use Case
Identify exactly what needs wireless connectivity. A warehouse scanner, autonomous vehicle, security camera, industrial controller, and worker smartphone have very different requirements.
2. Perform an RF Site Survey
Measure building size, walls, metal equipment, outdoor areas, interference, device movement, and expected traffic. Radio count should come from RF design rather than guesswork.
3. Determine Available Spectrum
Spectrum rules differ by country. The United States, for example, provides CBRS shared spectrum that several private-network vendors support. Other countries reserve or license different bands for local enterprise networks.
4. Select LTE, 5G, or Both
Do not buy 5G only because the name sounds newer. Existing industrial devices may work perfectly on LTE. Dual-mode systems can protect that investment while providing a path to 5G.
5. Choose the Core and RAN
The RAN handles wireless communication with devices. The core authenticates users, applies policies, routes traffic, and connects private cellular to enterprise networks and applications.
6. Provision SIMs or eSIMs
Private cellular normally uses SIM-based identities. Each authorized device receives credentials that allow it to join the network.
7. Integrate the Network
Connect private 5G to VLANs, firewalls, identity systems, application servers, cloud environments, and operational technology as required.
8. Test Real Workloads
Do not stop after a speed test. Move scanners, robots, vehicles, or workers around the actual site. Test handoffs, latency, application response, uplink performance, failure recovery, and coverage at difficult locations.
Ericsson describes private 5G deployment in similar stages: planning and design, setup and installation, IT/OT integration, validation, and network optimization.
Private Wireless Network Security
Private does not automatically mean secure.
Private LTE and 5G have useful security foundations. SIM or eSIM credentials give each cellular endpoint a defined identity, and organizations can keep selected traffic inside their own network. Dedicated or protected spectrum also reduces some interference concerns found in shared unlicensed environments.
But administrators still need to secure the core, management platform, edge servers, APIs, switches, firewalls, radios, and connected devices. A flat network in which every camera, tablet, robot, and controller can reach everything else creates unnecessary risk.
Segment devices by role. Restrict administrative access. Patch radio and core software. Protect management accounts with strong authentication. Log configuration changes. Connect the private network to existing zero-trust and identity policies where possible.
The right mindset is simple: private 5G is a security architecture component, not a replacement for cybersecurity.
Private 5G vs. Wi-Fi 7
Private 5G and Wi-Fi 7 will often work together.
| Requirement | Wi-Fi 7 | Private 5G |
|---|---|---|
| Laptops and normal office devices | Excellent | Usually unnecessary |
| BYOD support | Excellent | More complex |
| Large outdoor areas | Possible but AP-heavy | Strong |
| Fast-moving industrial devices | Good with proper design | Strong |
| SIM-based authentication | No | Yes |
| Dedicated cellular spectrum | No | Yes, depending on deployment |
| Installation simplicity | Usually easier | More complex |
| Device ecosystem | Very broad | More specialized |
| Initial cost | Usually lower | Usually higher |
| Industrial mobility | Good | Major strength |
Wi-Fi wins for everyday connectivity because it is inexpensive, familiar, and supported by almost every laptop and phone.
Private 5G becomes more compelling for operational technology that moves around large or difficult environments. Ericsson explicitly describes the technologies as complementary, while Berg Insight’s 2026 market report expects Wi-Fi to remain complementary to private LTE/5G even as Wi-Fi 7 adoption grows.
A smart factory may therefore use Wi-Fi 7 for office users and visitors while putting autonomous vehicles, scanners, machine-vision cameras, and critical industrial systems on private 5G.
Private Wireless Technologies to Watch
The next phase of private wireless is less about faster phones and more about connecting machines to local computing and AI.
5G RedCap aims to reduce device complexity for cellular IoT applications that do not require the full performance of premium 5G hardware. That could help expand the range of sensors and industrial devices capable of joining private 5G.
Edge computing is also becoming more important. Instead of sending every video frame or machine reading to a distant cloud region, companies can process information locally. That reduces unnecessary data movement and can improve response time for automation and AI workloads.
Private 5G plus edge AI is already showing up in 2026 vendor strategies. NTT DATA and Ericsson, for example, are combining managed private 5G with edge AI and what they describe as physical AI for industrial environments.
Open RAN, network slicing, neutral-host infrastructure, AI-assisted operations, and tighter Wi-Fi/private-5G management will also shape vendor competition.
The biggest change may be organizational rather than technical. Private 5G is moving from isolated telecom trials toward systems that enterprise IT and OT teams can actually operate.
Private Wireless Vendor Buying Checklist
Before signing a contract, check the full lifecycle rather than only the radio specifications.
- Confirm whether the solution supports LTE, 5G, or both.
- Verify supported spectrum in every country where you will deploy.
- Ask whether the 5G core runs on-premises, in the cloud, or both.
- Determine where application data will be processed.
- Confirm who handles spectrum licensing or shared-spectrum access.
- Check indoor and outdoor radio options.
- Verify compatibility with your existing industrial devices.
- Confirm SIM and eSIM provisioning processes.
- Test integration with LAN, Wi-Fi, VLANs, firewalls, and identity systems.
- Ask who performs the RF survey and installation.
- Require clear software-update and security-patching policies.
- Compare upfront cost with three-year and five-year operating cost.
- Check how the platform scales across additional buildings or countries.
- Ask what happens to support if the product line is sold or discontinued.
- Run a production workload pilot before committing to a large rollout.
Frequently Asked Questions
What Is a Private Wireless Network?
A private wireless network is dedicated to one organization rather than being open to general public users. In modern enterprise networking, the term often refers to private LTE or private 5G. The organization controls coverage, device access, network policies, and integration with business systems.
How Much Does a Private 5G Network Cost?
Private 5G costs vary from tens of thousands for small installations to hundreds of thousands or more for large industrial sites. Radio count, core software, spectrum, installation, device compatibility, integration, edge computing, and ongoing management all affect the final cost. Always request pricing based on an RF design rather than using a generic per-site estimate.
How Do I Create a Private Wireless Network?
Start by defining the application and coverage area. Perform a radio site survey, determine which spectrum you can use, select LTE or 5G technology, deploy the RAN and cellular core, provision SIMs, integrate the system with your LAN and applications, apply security controls, and test real workloads before full production.
What Are Some Examples of Private Networks?
Examples include private Wi-Fi LANs, VLANs, VPNs, private cloud networks, private LTE networks, and private 5G networks. A factory private 5G network connecting robots and scanners is one example. A university’s internal Wi-Fi network is another.
Is Private 5G Better Than Wi-Fi?
Not automatically. Wi-Fi remains better for most laptops, office users, visitors, and general internet access because devices support it widely and deployment costs are usually lower. Private 5G becomes more attractive for high mobility, broad outdoor coverage, industrial automation, controlled radio capacity, or applications that benefit from SIM-based identity.
Do You Need a SIM Card for Private 5G?
Usually, yes. Devices authenticate to private cellular networks using a physical SIM or eSIM profile. SIM-based identity is one reason companies can apply precise access and device policies to private LTE and 5G endpoints.
Can a Small Business Use Private 5G?
Yes, but most small businesses do not need it. A shop, small office, restaurant, or normal school will usually receive better value from professionally designed Wi-Fi. Private cellular becomes reasonable when the business operates warehouses, industrial machinery, large outdoor areas, mobile equipment, or applications where wireless downtime creates significant financial risk.
Final Thoughts Before Choosing a Private Wireless Vendor
The private wireless market in 2026 is no longer a contest to see which vendor can write 5G on the largest brochure. Real differences now appear in deployment models, industrial integration, management, spectrum support, edge computing, security, and long-term operating cost.
Ericsson is a strong starting point for industrial private 5G. Siemens stands out when private cellular needs to sit close to factory automation. HPE Aruba, Celona, and Cisco make strong cases for enterprise IT teams. Mavenir brings a more open, cloud-native approach. Samsung offers a broad end-to-end cellular stack. Verizon Business and NTT DATA make sense when managed service matters more than owning every technical component.
Nokia still has one of the market’s most important installed bases, but its 2026 Enterprise Campus Edge disposal process makes vendor-roadmap checks essential for new projects.
The best decision starts with one question: What problem must this network solve?
If you only need better office coverage, improve Wi-Fi.
If you need reliable connectivity for robots, vehicles, scanners, cameras, industrial systems, or people moving across a difficult site, private LTE or 5G deserves a serious look.
Choose in this order:
Use case → Site conditions → Spectrum → Existing IT/OT → Security → Management model → Total cost → Vendor
That process will produce a much better private wireless network than choosing the vendor name first.
