Utility networks span hundreds of kilometres, operate in remote and hazardous environments, and carry communications that cannot fail. Private LTE and 5G give utility operators the coverage, security and control that public networks cannot provide — if the network is planned correctly from the start.
Private LTE and 5G networks also offer stronger security and full operational control, which are essential for protecting critical infrastructure and meeting regulatory requirements. With assets spread across vast and remote areas, utilities need wide-area coverage that commercial networks often cannot provide. Private wireless systems enable consistent communication with field crews and support the growing number of connected devices used for grid automation, smart meters, sensors, and advanced monitoring.
Why utilities need private LTE/5G networks
Public mobile networks are not built for utility operations. They go down during the same grid events that utility operators need to respond to, cannot guarantee the coverage depth or latency that SCADA and AMI systems require, and expose operational data to shared infrastructure. Private LTE and 5G networks solve this directly: the operator controls the spectrum, the core, the coverage zones and the security configuration independently of public infrastructure, across every substation, field asset and remote installation the operation depends on.
RAN planning for private wireless networks in the utility sector focuses on designing highly reliable, secure, and wide-area coverage that aligns with the operational demands of critical infrastructure. This process involves determining optimal base-station locations, and modelling coverage to support both fixed and mobile use cases, including field crews, automation equipment, and millions of connected sensors.
The utility private network planning challenge
Utility private networks are not campus deployments. The infrastructure they must cover is geographically dispersed: substations kilometres apart, pipeline monitoring points across open terrain, distribution assets in urban and rural environments simultaneously. The devices they serve range from high-bandwidth crew communications to low-power sensors. And the reliability standard is continuous; grid monitoring and operational safety systems cannot tolerate outages.
RAN planning for utility private networks means designing wide-area coverage that reaches every operational site without gaps, with capacity for both high-bandwidth and low-power use cases, and interference management across large geographic footprints. Getting base-station placement, antenna configuration and frequency planning right across distributed infrastructure requires simulation, not estimation.
What the network must support
- Grid monitoring and SCADA: low-latency connectivity to substations, switching stations and remote monitoring points. Coverage gaps in a SCADA network are operational failures.
- AMI and smart metering: high device density at low power levels, across urban and rural environments simultaneously.
- Field crew communications: reliable voice and data for engineers and technicians working on distributed assets, including locations where public coverage is absent.
- Grid automation and protection: deterministic, low-latency communication between protection relays and control centres for automated switching and fault detection.
- Remote site monitoring: pipelines, renewable energy installations and remote generation assets, often beyond any public network footprint.
Planning wide-area utility networks with Atoll and Atoll One
Atoll is used by utility operators to plan wide-area private LTE and 5G networks across distributed infrastructure. It models outdoor terrain accurately across large geographic areas, places base stations to maximise coverage efficiency across the full service territory, and validates that every operational site is within coverage, however remote. Where sites include substations or control buildings, indoor modelling runs within the same project.
For site-level deployments: a substation campus, a wind farm, a regional distribution cluster, Atoll One provides the same outdoor and indoor planning capability in a tool designed for private network projects. Many utility operators use Atoll One for site-level work and Atoll for the wider network.
Frequently asked questions
Public networks go down during grid events, cannot guarantee the latency SCADA and AMI require, and share infrastructure with public users. Private LTE and 5G give the operator direct control over coverage, capacity, security and uptime, independently of public network availability.
SCADA and grid monitoring, AMI and smart metering, field crew communications, grid automation and protection systems, and remote site monitoring across pipelines, substations and renewable energy installations.
Scale and distribution. The planning challenge is achieving reliable coverage across every node of a network that may span hundreds of kilometres — including remote locations with no public coverage. Wide-area propagation modelling across real terrain and accurate base-station placement across a large geographic footprint are the core requirements.
Atoll One for site-level deployments — a substation campus, a generation facility, an industrial site. Atoll for wide-area or multi-site networks spanning a large geographic area. Many utility operators use both at different stages or for different parts of their network.
