How do you build a highly reliable communication network for a national-scale utility when fibre optics cannot reach most substations due to terrain? For EDCO in Jordan, the answer was a fully redundant UHF network built on RipEX and RipEX-HS.

Challenge: Extreme Reliability Requirements for a Nationwide SCADA/DMS/AMR System
The Electricity Distribution Company (EDCO), established in 1997, is responsible for electricity distribution planning, installation, operation and maintenance across more than half of Jordan.
In 2015, EDCO launched a tender for a major project: to connect selected substations to a new SCADA / DMS / AMR control centre in Amman. The system needed to:
- monitor and control both existing and future distribution networks
- ensure continuous visibility and management across all EDCO regions
- meet the highest reliability and redundancy standards
- comply with IEC 60870-5-104 requirements
- support long-term expansion and evolving operational needs
While EDCO initially hoped to use fibre optics, extensive field analysis revealed that physical constraints made fibre feasible only in a very limited part of the territory.
Solution: RipEX and RipEX-HS Redundant Architecture in 400 MHz UHF
After extensive research and testing, EDCO concluded that a UHF data radio network could provide the required availability – but only when using best-in-class equipment.
RipEX and its 1+1 hot-standby version RipEX-HS were selected due to:
- full redundancy with automatic switchover
- extremely high reliability and availability
- dual AC/DC power supplies in every HS unit
- support for IEC 104 using Base Driven protocol
- advanced routing functionality
- RF output power up to 10 W where required
- proven long-term robustness in harsh environments
Deployment: Custom-Built RACOM Cabinets and Turnkey Integration
The initial deployment includes:
- 12 RipEX-HS redundant stations
- 25 RipEX radio modems
- Siemens Ruggedcom switches
- ABB RTUs
All equipment is delivered inside custom indoor wall-mount cabinets, designed, wired and tested by RACOM to EDCO’s exact specifications. This ensured:
- fast installation
- complete uniformity across sites
- minimal work required on-site
- simplified project logistics for the contractor
RACOM provided extensive support:
- remote technical assistance
- detailed design consultations
- on-site commissioning visits
- ongoing troubleshooting and optimization
This support was crucial to keeping the multi-stage project on schedule.
Results: A Reliable, Expandable Backbone for National Power Distribution
EDCO and its contractor reported high satisfaction with:
- product quality
- network reliability
- responsiveness and professionalism of RACOM support
- the turnkey nature of RACOM’s cabinet solution
The RipEX-based UHF network now provides:
- mission-critical SCADA connectivity
- reliable operation in challenging geographies
- redundancy across all primary sites
- a clear path for future network expansion
Based on the project’s success, EDCO is already discussing additional phases to further extend the RACOM-powered communication network across Jordan.
