Cellular routers are used in the utilities industry for several compelling reasons, offering unique advantages that cater to the specific needs and challenges faced by utility companies. Here are the primary reasons:

1. Reliable Remote Connectivity
  • Wide Coverage: Cellular networks provide extensive coverage, especially in remote or hard-to-reach areas where traditional wired connections are impractical.
  • Uninterrupted Service: Cellular routers offer reliable connectivity essential for real-time monitoring and management of utility assets.
2. Scalability and Flexibility
  • Easily Expandable: Cellular networks can be easily scaled to accommodate additional devices and sensors without extensive infrastructure modifications.
  • Quick Deployment: Cellular routers can be quickly installed and activated, allowing for rapid deployment in new sites or during emergencies.
3. Cost-Effectiveness
  • Reduced Infrastructure Costs: Avoids the high costs associated with laying and maintaining wired connections, especially in remote or rugged terrains.
  • Lower Maintenance: Cellular networks require less maintenance compared to traditional wired infrastructure, reducing operational costs.
4. Real-Time Data Access and Monitoring
  • Immediate Data Transmission: Enables real-time data transmission from remote sites to central control systems, facilitating timely decision-making and proactive maintenance.
  • Enhanced Monitoring: Supports continuous monitoring of critical infrastructure like power grids, water treatment plants, and pipelines.
5. Enhanced Security
  • Secure Communications: Many cellular routers support secure VPN connections, encryption, and other security features to protect sensitive data transmitted over the network.
  • Isolation from Public Networks: Cellular networks can be isolated from public internet access, reducing the risk of cyberattacks.
6. Disaster Recovery and Redundancy
  • Network Redundancy: Provides a backup communication channel in case of failures in primary networks, ensuring continuous operation during disasters or network outages.
  • Emergency Response: Facilitates quick restoration of services and coordination during emergencies, helping utility companies maintain essential services.
7. Support for Advanced Technologies
  • Internet of Things (IoT): Cellular routers are integral to IoT applications, enabling seamless integration of smart meters, sensors, and other IoT devices.
  • SCADA Systems: Essential for Supervisory Control and Data Acquisition (SCADA) systems used for remote monitoring and control of industrial processes.

Replacement Applications

PSTN Replacement

PSTN is used by utilities to retrieve telemetry data for operational and governance purposes whilst also providing remote access to SCADA and HMI systems.

Due to the rise in internet usage across the utility market, it has meant the legacy PSTN network is no longer a viable option for communicating voice and data. The Public Switched Telephone Network or PSTN will reach the end of life in 2025, leaving Utility providers who utilise the network at risk of losing network visibility and management.

Because of this risk in collaboration with our OEM partner, we have formed a solution that seamlessly integrates within a PSTN network maintaining connectivity utilising cellular networks with support for fibre and DSL connection. We have also implemented end-to-end Encryption, SSL through GRE over IPsec, Stateful Firewall features and intelligent control/failover protection.


Paknet Replacement

Launched in 1990, Paknet provided a data-only network using cellular radios as endpoints. It was used widely for applications such as burglar alarms through to network monitoring on critical infrastructure.

Due to the age of the technology and upkeep costs, the current network owner Vodaphone took the decision to shut down the network by mid-2022 leaving subscribers to replace equipment or integrate a solution. In the case of some utility networks, this could be in the tens of thousands of locations.

To mitigate this risk we have worked closely with our OEM partners to develop a Paknet emulation feature providing a plug-and-play solution for integration into legacy networks, Replacing the Paknet link with a low-cost cellular solution.

Read our case study below to find out how we have supported UK Power Networks in their Paknet Replacement Programme.

Case Study


Cherry & White work closely with UK Power Networks on their critical infrastructure network across multiple contracts, which cover over 19 million people (8.3 million homes).
Together with our partners, we developed a cost-effective, reliable solution to replace outdated Vodafone Paknet Pads across the UKPN network. By integrating Paknet emulation onto a cellular router using UMTS/LTE networks, we seamlessly modernized their legacy SCADA equipment.
