“Private wireless and public mobile coverage solve different problems. Together, they create a more complete connectivity foundation for the enterprise.”
The Challenge: Dependable Cellular Across Very Different Environments
Modern industrial enterprises increasingly depend on cellular connectivity, but the requirements inside a manufacturing plant can be very different from those inside an office, warehouse or engineering facility.
For one global manufacturer, private wireless was already an important part of its digital manufacturing strategy. The company uses Nokia Digital Automation Cloud (DAC) to support industrial applications that require high availability, enterprise control and reliable connectivity.
But employees, contractors and visitors had another critical need: dependable public mobile coverage on the phones they already carry.
Inside large corporate facilities, outdoor mobile networks could not consistently provide that experience. Building materials, expansive floor plans and challenging radio environments created weak signals and dead zones. Employees experienced dropped calls and sometimes needed to move elsewhere to get reliable service.
The challenge extended beyond any single building. With a diverse portfolio of offices, manufacturing plants, warehouses and other facilities, the company needed a repeatable approach that could support multiple mobile operators without requiring separate infrastructure and carrier negotiations at every location.
The Solution: Neutral Host Coverage That Complements Private Wireless
InfiniG deployed its Mobile Coverage as a Service (MCaaS) platform to provide reliable indoor public mobile coverage across initial corporate facilities.
Built on shared Citizens Broadband Radio Service (CBRS) spectrum and neutral host architecture, the solution supports AT&T, T-Mobile and Verizon subscribers through a common radio access network.
Employees and visitors can use their existing phones, SIMs and service plans. There are no special apps to install, no Wi-Fi calling workarounds and no changes to their normal mobile experience.
InfiniG also manages the technical integration and commercial relationships with participating mobile operators. Instead of requiring the enterprise to coordinate individually with each carrier, InfiniG handles onboarding, network integration, support and escalation.
This gives the customer a repeatable model for expanding indoor mobile coverage across additional facilities without treating every building as a separate carrier project.
Building on Nokia DAC Private Wireless
An important part of the customer's broader connectivity strategy is the ability to bring public mobile coverage and private wireless together.
The company already uses Nokia DAC for private cellular connectivity in industrial environments. InfiniG's established integration with Nokia DAC provides a path to add neutral host coverage using compatible shared radio infrastructure.
Through InfiniG Connect, the two networks maintain separate service paths:
- Private wireless: Nokia DAC connects authorized devices to the enterprise's private core, supporting industrial applications, operational control and isolated traffic.
- Public mobile coverage: InfiniG's neutral host platform connects ordinary mobile devices to participating operator networks for native voice, data, video and supported mobile safety services.
The device's SIM and selected network determine which service path it uses.
Sharing compatible radio infrastructure does not mean merging the networks or compromising the enterprise's control over private-network traffic.
InfiniG and Nokia have an established technology partnership supporting this approach, allowing enterprises to combine Nokia DAC private wireless with multi-operator public mobile coverage while preserving their existing private-network capabilities.
For manufacturers already investing in private cellular, this architecture offers a practical way to extend the value of that infrastructure.
The Experience: Cellular Coverage That Just Works
The most visible benefit of InfiniG's neutral host solution is also the simplest: employees and visitors can use their existing mobile phones inside buildings where coverage was previously unreliable.
There is no need to change mobile operators, install applications or depend on Wi-Fi calling to compensate for weak indoor cellular signals.
Key takeaway: Reliable cellular coverage should work on the phones employees already have, without requiring them to change how they connect.
In industrial environments, dependable public mobile connectivity also plays an important role in workplace communications and safety.
Alongside everyday voice, messaging and data services, participating mobile networks can support native 911 calling and Wireless Emergency Alerts. These capabilities help provide a familiar communication experience for employees, contractors and visitors, including people who are not authorized users of the enterprise's private wireless network.
Emergency calling features, indoor location capabilities and alert delivery depend on the participating operator, device and site configuration.
The Results: A Foundation for Multi-Site Expansion
InfiniG's initial neutral host deployments demonstrate a repeatable approach to providing indoor public mobile coverage across a large enterprise.
Key outcomes include:
- Multi-operator coverage: AT&T, T-Mobile and Verizon service across initial deployed facilities.
- A familiar mobile experience: Employees use their existing phones, SIMs and mobile plans without additional applications or workarounds.
- Improved indoor connectivity: Coverage addresses building areas that outdoor carrier networks could not reliably serve.
- Simpler operator management: InfiniG handles mobile-operator relationships, technical onboarding, support and escalation.
- A repeatable deployment model: A consistent neutral host approach designed to extend across corporate offices, manufacturing facilities, warehouses and other enterprise environments.
- A path to shared infrastructure: Established Nokia DAC integration creates opportunities to support private wireless and public mobile coverage through compatible shared radio infrastructure while keeping their networks separate.
The initial deployments focus on addressing indoor public mobile coverage needs. The broader private wireless and neutral host architecture provides a foundation for future opportunities to use shared infrastructure wherever the technical requirements and site configurations allow.
The Bigger Picture: One Cellular Strategy, Two Distinct Networks
Industrial enterprises increasingly need two kinds of cellular connectivity.
Private wireless provides the control, availability and traffic isolation required for manufacturing and operational applications. Public mobile networks keep employees, contractors and visitors connected through the phones and service plans they already use.
These are complementary requirements, not competing approaches.
Key takeaway: Private and public cellular networks have different jobs. Shared infrastructure can support both while preserving separate traffic paths and enterprise control.
For large organizations, combining these capabilities offers a more flexible approach to enterprise connectivity.
Manufacturers can continue investing in the private networks that support their operational requirements while using InfiniG neutral host technology to bring dependable public mobile coverage into their buildings.
And because InfiniG manages the participating mobile operators, the enterprise can focus on its facilities and business operations rather than negotiating and maintaining individual carrier relationships.
The result is a cellular strategy designed to grow with the organization: private network control, public mobile coverage and compatible shared infrastructure that supports both.
