Northern Ireland Water (NIW) is a government-owned water utility serving a population of 1.7 million across the province of Northern Ireland. With the second largest network of pipelines, water and wastewater treatment plants in the UK, NIW operates the largest single, radio-based telemetry network on the island of Ireland.
This network has formed a key part of NIW infrastructure for the past 10 years and provides real time monitoring of critical infrastructure. In 2011 EMR was awarded a €1.8 million contract to upgrade the network from the legacy analogue radio technology to a state-of-the-art digital radio network based on the 4RF Aprisa platform.
The NIW telemetry network comprises over 1800 radio sites. As part of the migration to digital, EMR was charged with the task of maintaining service to all sites, the integration of the new system with the existing Serck SCADA system together with the provision of a comprehensive network management system. After a careful assessment of the project requirements EMR selected the 4RF Aprisa SR digital radio platform combined with Castle Rock’s SNMPc management software suite. Aprisa SR is a family of IP radios incorporating the highest levels of security and manageability combined with an unrivalled level of reliability.
Castle Rock is the leading network management software deployed in the IT sector. The implementation of Castle Rock allowed EMR to have full visibility of the radio network during rollout, facilitating optimisation and allowing NIW gain confidence in the network from day one and provide NIW with invaluable performance monitoring into the future.
4RF is a New Zealand based specialist manufacturer of high availability RF solutions for the utility and military markets with a worldwide customer base. In 2007, having established it’s enviable reputation based on the provision of solutions in the microwave frequency bands, 4RF turned their R&D attention to UHF radio for the developing digital radio telemetry markets. The Aprisa SR was the product of four years development effort combined with 4RF’s innate knowledge of the utility.
About the Aprisa SR
The Aprisa SR is a family of fully integrated digital radios designed to meet the evolving needs of utility customers. Being fully IP enabled, the Aprisa SR slots in seamlessly with the modern distributed automation, monitoring and control systems of the water and energy utility sectors, while the inclusion of serial communications ports allows integration with older, legacy systems. Because of the nature of the networks on which it is deployed, security has been built in the form of AES256 encryption and comprehensive password protection. Where there is a requirement for redundancy the Aprisa SR is available in a fully managed hot standby configuration. The Aprisa SR is fully SNMP compliant allowing a high level of realtime monitoring and remote diagnostics, allowing control room operators verify that the radio network is operating effectively and address issues before they become critical.
