Intelligent Edge in Smart Utilities

All-in-One Industrial IoT Gateways simplify deployment and scale up to reduce CapEx and OpEx

Energy utilities, including power, water and gas, have been one of the key sectors demonstrating fast and steady adoption of industrial IoT (IIoT) technologies. This is evident by forecasts placing the global market for IoT in utilities at nearly $54 billion by 2024, representing a growth of 13.5% from 2019¹ . The reasoning for this trend is clear – by making sensor-based meters and other end points “smart”, utilities expect to benefit from higher efficiency, easy scalability and improved operations, as well as to minimize risk and downtime. To help achieve these benefits, there’s a growing use of cloudbased Big Data, analytics and dashboards, which provide critical real-time insights for C-Level decision makers. These insights are required to ensure that the utility company is able to meet fluctuating customer demand at all times, with no hiccups.

However, going smart isn’t enough. In a typical utility company, thousands or more of these end points need to be connected , sometimes from remote locations with no network reach. For example, data from program logic controller (PLCs) needs to be aggregated and hauled securely over various wireline and wireless networks to the control center. In many cases, there’s also the issue of connecting existing devices from older generations and making sure they can “speak” with the control room/management system that are using new SCADA protocols such as MQTT. And last but certainly not least, given the rise in cybersecurity vulnerabilities that goes hand in hand with hyper-connectedness, such deployments require in addition to secure tunnels, a remote Operational Technology (OT) security probe. The latter connects to a central OT security system, for example for anomaly detection.

Until now, all of the above would have meant that five (5!) different appliances would be required at each remote site (a PLC gateway, a LoRaWAN gateway, a ruggedized router/firewall, a protocol converter, and a cellular modem). When multiplied by the number of connected sites, this results in a massive footprint that would prove to be very difficult to manage and maintain.

RAD’s Secure Industrial IoT GW Solutions with Edge Computing Simplify Smart Utilities Deployments

RAD offers ruggedized, multiservice and compact Industrial IoT (IIoT) gateways with Edge Computing and an advanced security information and event management (SIEM) that eliminate the multi-appliance clutter described above. They also save CapEx and OpEx, and allow the flexible addition of functions, as needed. These IIoT gateways combine multiple wired and wireless interfaces to connect large volumes of sensors, meters and other smart devices over various WAN links in a secure manner. RAD’s IIoT solution hosts both networking and non-networking functions on the same hardware, to reduce the number of devices in the network and increase security and reliability.

  • Transparent delivery of legacy traffic from serial-based devices
  • Ruggedized devices suitable for harsh environments
  • Upgradeable to SD-CloudAaccess support for application-aware traffic distribution across multiple links

Edge Computing

Edge Computing allows hosting of various software-based functionalities on an edge device, so that less appliances are required there, introducing cost and space savings and flexibility to add future functions. Such software-based functions allow local processing of the data produced by sensor-rich assets, rather than sending it all the way to a centralized control center. As a result, the following benefits can be achieved:

  • Ultra-low latency: As the data doesn´t need to be sent across long routes to data centers or cloud services, better deterministic response time due to low latency can be achieved.
  • Trigger local, real-time actions when anomalies are detected.
  • Save on cellular data plan costs since not all traffic needs to be backhauled across metered networks
  • Enable smart data collection for advanced support programs or predictive maintenance.
  • Tighter cyber security as less assets require protection.
  • Flexibility in choosing best-of-breed software edge applications.

With Edge Computing capabilities, RAD’s SecFlow supports more than secure networking functionality, providing the option for onboarding third-party software using containers to further reduce the number of appliances required in the field. In the context of large-scale smart utility deployments, this integrated gateway approach simplifies operations and reduces the cost of connecting thousands of remote IoT assets, while strengthening security.

Harnessing LPWAN Connectivity

Low-power WAN (LPWAN) technologies including LoRaWAN, LTE-M and narrowband IoT (NB-IoT) support large scale connectivity for collecting sensor data. Such applications tend to require sporadic connectivity for low bandwidth data transfer. LoRaWAN in particular has increasingly been deployed in smart utility applications due to its use of unlicensed spectrum and the availability of standardized, low-cost modules with long battery life. RAD’s IIoT gateways use LoRaWAN to connect smart utility devices to the cloud for data processing and management gateways use LoRaWAN to connect smart utility devices to the cloud for data processing and management.

Energy Substation Deployment Example

RAD’s SecFlow IIoT Gateway solution is being used by a large power utility as part of a project to modernize its power distribution network, which serves more than 90 million subscribers. The SecFlow collects field data from Modbus RTUs and backhauls it over public 3G/4G cellular links to the central HMI control room. IPsec is used to encrypt the data and ensure it’s protected from cyber-attacks.

RAD’s Security Gateway aggregates all IPsec tunnels from the remote sites, serving as a state-of-the-art VPN aggregator with a stateful firewall, real-time Radius decryption and an automated PKI (X.509) with an integrated DNS resolver.

The entire network is managed by the RADView management system, enabling intuitive and automated provisioning and monitoring of the thousands of RTUs and gateways in the network
