Background 

ESKOM is the seventh largest electricity producer and ninth largest electricity seller in the world, with the world's  largest dry cooling power station, supplying 95% of South Africa's electricity consumption and 60% of Africa's electricity consumption. The company needed to replace several out-of-date radio networks with a single modern digital  system. Kirisun supplied a DMR Trunking solution, which provides unified indoor and outdoor communications across  widely varied terrain and harsh environments.

Challenge 

• Delivering a unified, reliable and secure DMR network across the region’s varied environments to support  excellent indoor and outdoor coverage.

• The radio equipment was old and difficult to operate and maintain.

• Stability of system: Improve the system stability to ensure the 24hours communication service.

• The company placed particular emphasis on network coverage, redundancy and high availability.

Solution 

Based on the analysis of the ESKOM’s requirements, Kirisun offered the following solution: 

• Build 2 DMR base stations in the command center of the company. 

• Kirisun provided 2000+Pcs Intrinsically safe DMR radios to all the staff. 

• The radio was equiped with 4W RF power to have a larger coverage compared with other terminals.

Benefits

• Unified and modern digital network

The DMR Tier III trunking network replaced multiple separate old networks to provide much more efficient communications across the region.

• Optimum indoor and outdoor coverage

Besides implementing the end-to-end DMR trunking solution, Kirisun was also able to offer professional network  planning and design services to ensure the optimum coverage for both indoor and outdoor areas.

• Expanded coverage and reduced infrastructure costs

Kirisun’s trunking base station and site design solutions deliver a high level of reliability and wide coverage to  ensure that the overall system is efficient, stable and easy to maintain. Due to the high-power feature, it requires  fewer base stations to cover the same area. Therefore, less infrastructure investment is required.
