This subject was discussed on the Industrial Wireless Forum last fall. This blog expands on the topic and provides an in-depth view of the challenges for utilities and the solutions by Moso Networks and partners.

Electric, gas, and water utilities operate large networks of substations, pipelines, smart meters, and field crews. However, many field and backhaul links still rely on leased copper, legacy serial radios, or Wi-Fi systems that weren’t designed for outdoor use or deterministic performance over long distances. These limitations create risk as utilities modernize supervisory control and data acquisition (SCADA), expand advanced metering infrastructure (AMI), and integrate distributed generation.

Private 5G provides a secure, high-availability wireless layer for mission-critical utility operations in both congested urban RF environments and remote areas with limited commercial cellular coverage. It delivers licensed spectrum, predictable latency, SIM-based access control, and wide-area outdoor coverage without depending on public carriers. With integrated solutions such as the Moso Canopy radio and the Druid Raemis packet core, utilities can deploy low-latency, high-bandwidth connectivity that is resilient, easy to manage, and cost-efficient.

Why Utilities Need Private 5G

Public and unlicensed wireless systems weren’t designed for long-range industrial utility environments. Substations, pumping sites, solar farms, and distribution equipment operate in RF-challenged areas where signal strength fluctuates or service drops entirely. Best-effort links also introduce jitter and latency that SCADA and protection systems can’t tolerate.

Private 5G gives utilities full control of coverage, security, QoS, and lifecycle management. Licensed or managed spectrum mitigates congestion, while SIM-based authentication and network slicing isolate operational traffic from enterprise IT and the public internet. Remote industrial and utility sites are often early adopters of private 5G, since commercial LTE signals don’t propagate reliably around metal structures, elevation changes, and underground assets.

With Moso Canopy and the pre-validated Druid Raemis core, deployment is streamlined. Radios auto-discover, provisioning runs through a unified interface, and the entire network can be delivered as a managed service. Utilities gain carrier-grade wireless capability without carrier-scale complexity, which is especially important in substations where reliable connectivity supports monitoring, security, and field operations.

To illustrate key operational differences, the table below compares private 5G delivered by Moso Canopy radios with the Druid Raemis core to public LTE and Wi-Fi options used in utility communications.

Substation and Field Operations Connectivity

Substations are among the most communications-sensitive points in a utility network. Protection relays, fault monitoring, and SCADA systems require deterministic latency and secure transport, even during storms or fiber outages. Legacy copper, serial radios, and microwave links are costly to maintain and prone to disruption. Wi-Fi and public LTE often deliver inconsistent coverage in substation yards, where transformers and metal structures create heavy interference.

Private 5G provides a dedicated wireless layer engineered for outdoor industrial coverage. Licensed spectrum reduces RF noise, and SIM-based access isolates OT devices to ensure deterministic performance for critical workloads. When fiber fails, private 5G maintains local connectivity, providing a resilient last-mile link to field assets and backhaul.

With Moso Canopy and Druid Raemis at the edge, SCADA and protection traffic continue operating while upstream connectivity is restored. A single Moso radio can cover an entire substation yard, connecting cameras, relays, RTUs, sensors, and field tablets. Radios auto-discover the Druid Raemis core, eliminating manual CLI scripting.

AMI and Distributed Grid Assets

AMI platforms and grid-edge IoT devices generate large volumes of telemetry across wide service territories. Millions of meters, reclosers, EV chargers, regulators, and DERs transmit frequent updates. While many utilities backhaul this data over public LTE, neighborhood congestion and carrier outages often degrade performance. Wi-Fi mesh and other unlicensed wireless systems are also susceptible to interference and unpredictable latency.

Private 5G provides a dedicated RF environment for AMI and distribution automation, supporting thousands of devices per sector. SIM-based onboarding ensures immutable identity for each device, and QoS separates metering traffic from protection signals. Utilities typically start with distributed sensors and automation equipment, then expand to mobility and video applications.

Private 5G also improves backhaul economics. Instead of carrier data plans or new fiber builds, a single Moso radio can cover neighborhoods or solar sites, delivering deterministic uplink and reliable propagation through metal enclosures and foliage. With Moso Canopy and the Druid Raemis core, utilities can segment traffic by feeder or region, simplifying compliance and lifecycle management.

Storm Response, Mobility, and Field Crews

Storm recovery is one of the most difficult communications challenges for utilities. If fiber is down or commercial LTE is saturated, field crews lose connectivity precisely when operations depend on it. Wi-Fi hotspots have limited range, and satellite links are costly with constrained bandwidth.

Private 5G provides a resilient mobile communications layer for crews, substations, and command centers. Utilities are increasingly adopting portable private 5G systems that deploy in hours, delivering local coverage and core services without waiting for fiber restoration. With Moso Canopy and the Druid Raemis core at the edge, the network continues operating locally if backhaul fails, keeping SCADA, telemetry, cameras, and push-to-talk applications online.

A single Moso Canopy radio covers staging areas, mobile command units, and damaged sites while supporting tablets, safety cameras, drones, and outage coordination tools. Radios auto-discover and provision through the Druid Raemis core, reducing temporary network complexity and lowering O&M overhead. Because the system interoperates with SCADA, GIS, and workforce management platforms, crews maintain secure mobility between sites and access outage maps and digital work orders that accelerate restoration and reduce truck rolls.

Cybersecurity and Regulatory Compliance

Cyber risk increases as utilities digitize substations, integrate DERs, and deploy millions of edge devices. Public LTE further expands the attack surface, with traffic moving across networks the utility doesn’t control. Wi-Fi introduces similar exposure through third-party infrastructure and MAC-based access control vulnerable to spoofing.

Private 5G creates a closed, utility-owned domain that meets operational and regulatory requirements. SIM-based authentication assigns a verifiable identity to each device, and traffic segmentation prevents lateral movement between operational networks and enterprise IT. When segments are isolated at the packet-core level, a compromise in one zone can’t propagate into OT, supporting NERC CIP practices.

With Moso Canopy and the Druid Raemis core, utilities can efficiently and securely enforce network slices and QoS policies for SCADA, AMI, video, and workforce applications. Session-level monitoring and logging improve visibility and control without depending on public carriers.

Conclusion

Utilities are replacing legacy links, expanding AMI deployments, electrifying transportation, and supporting distributed generation. Private 5G delivers licensed-spectrum reliability, engineered outdoor coverage, and resilient operation if backhaul fails. Moso Canopy and the Druid Raemis core provide carrier-grade connectivity without telecom complexity through auto-discovery, centralized SIM provisioning, and isolated traffic that protects critical systems. From substations to storm response, private 5G is the communications foundation for secure, efficient utility operations.
