When OT and IT traffic share the same infrastructure, the boundary between production systems and everything else becomes a policy decision not an architectural one. Policies get misconfigured. Patches get skipped. And a ransomware event that starts on the IT side now has a pathway to production. Private 5G changes the architecture, not just the policy.
Private 5G is a private cellular network you own and operate on your own site. It runs on CBRS: shared 3.5 GHz spectrum the FCC opened for enterprise use, with no carrier subscription and no spectrum license to buy. The result is carrier-grade coverage, security, and reliability under your control.
How It WorksOT security was not a priority when production systems ran on isolated, air-gapped networks. Digitization changed that. Today, the same network carrying ERP data and email traffic often reaches SCADA systems, PLCs, and industrial controllers. That convergence brings operational visibility and new attack surface.
LG Private 5G creates hard network boundaries through 3GPP network slicing and SIM-based device authentication. OT devices are provisioned with SIMs that authenticate to the private network not to a shared credential. They connect to their dedicated slice and only that slice. A compromised IT device doesn't have a path to OT traffic, because they're not on the same logical network.
VLANs and firewall rules create boundaries that depend on perfect configuration.
Devices join with a password or by connecting to the right SSID.
Rogue access points, evil-twin, and deauth attacks target the open RF interface.
Slicing puts OT and IT on separate logical networks, separation by architecture, not policy.
SIM-based authentication: only provisioned devices connect, cryptographically.
Licensed CBRS spectrum and SIM credentials remove those Wi-Fi attack vectors.
Patient health information must be isolated from general network traffic. LG Private 5G provides dedicated network slices for clinical devices, with SIM-based authentication ensuring that only provisioned clinical devices connect to the protected slice. PHI stays on a network segment that doesn't touch general hospital connectivity.
Defense contractors handling Controlled Unclassified Information (CUI) require network isolation between CUI-bearing systems and general IT. LG Private 5G's SIM-based authentication and OT/IT slicing architecture directly supports CMMC network access control requirements without depending on policy enforcement alone.
The IEC 62443 framework defines security zones and conduits for industrial control systems. LG Private 5G's slicing architecture implements network zone separation at the radio access layer each zone gets its own slice with its own security policy, enforced before traffic reaches the wired network.
Electric utility operators subject to NERC CIP requirements need documented, enforceable separation between operational technology and corporate networks. LG Private 5G's architecture provides that separation with configuration documentation that directly supports compliance evidence requirements.
Pipeline operators managing OT systems subject to TSA security directives need defensible network segmentation between control systems and corporate IT. LG Private 5G's dedicated OT slice keeps pipeline control traffic on an isolated network that doesn't share a path with corporate applications.
Retail, hospitality, and consumer-facing operations handling personal data under CCPA, GDPR, or state privacy regulations need documented separation between consumer data and operational systems. LG Private 5G's slicing provides that separation with a clear architecture that supports compliance documentation.
Production systems, SCADA, and industrial controllers operate on a dedicated OT slice that is architecturally separate from the IT network. A security event on the IT side has no path to OT not because a firewall rule blocks it, but because OT devices aren't on the same network. LG Private 5G makes that separation a property of the infrastructure, not the configuration.
Every device on an LG Private 5G network authenticates with a SIM credential the same mechanism that authenticates devices on public 5G networks. Unauthorized devices can't join with a password or by connecting to the right SSID. Device authentication is cryptographic and provisioned, not credential-based.
LG's vCore can be deployed on-premises, keeping all traffic processing within the facility. Production telemetry, patient records, and regulated data never leave the building. Cloud outages don't affect operations. Compliance auditors get a clear, documentable architecture with data sovereignty that doesn't depend on a cloud provider's terms of service.
Medical devices, infusion pumps, and patient monitoring equipment connect to a dedicated clinical slice that is isolated from the general hospital network. Visitors on the guest network and employees on the corporate network have no path to clinical device traffic. HIPAA boundaries are enforced at the network layer, not the application layer.
Visitors, contractors, and temporary workers can access a guest slice with internet connectivity while remaining completely isolated from operational systems. There is no VLAN misconfiguration that could accidentally bridge them to production. The isolation is architectural guests are provisioned on a separate slice at the SIM level.
Security camera and access control systems handling sensitive footage and building access data benefit from dedicated network isolation. LG Private 5G provides a separate slice for physical security systems, keeping surveillance traffic off the same network that carries production or patient data.
LG Private 5G inherits the security architecture of public 5G networks 3GPP-defined authentication, encryption, and access control. The same standards that protect carrier networks protect your private network, applied on-premises under your control.
Slices are not VLANs with extra steps. Each slice has its own independent forwarding plane traffic on one slice cannot reach another slice without explicit policy, which doesn't exist by default. OT/IT separation is enforced at the radio layer before traffic reaches the core.
LG Private 5G operates in CBRS Band 48 a licensed-priority spectrum band that is not accessible to consumer devices. Rogue device association, Wi-Fi deauthentication attacks, and evil twin access points are not applicable attack vectors. The RF interface requires a provisioned SIM to access.
Regulatory frameworks for OT security, healthcare data, and critical infrastructure are expanding in scope and enforcement. The architecture you build today needs to support compliance requirements that don't fully exist yet. LG Private 5G's standards-based architecture documented, auditable, and independent of vendor-specific policy enforcement gives you a foundation that compliance frameworks are designed to recognize.
