Multisite DMR system strengthens comms for mining group

Caltta Technologies, a provider of professional and critical communications solutions, has announced the successful deployment of a multisite DMR Enhanced Communication System (ECS) for a key mining group in Uzbekistan.

The project was delivered in collaboration with Radiocom Holding Group, Caltta’s local partner in Uzbekistan, providing the mining operator with communications infrastructure designed to support safer, more efficient and better-coordinated operations. The deployment addresses the demanding communications requirements of large-scale mining operations, where extensive geographic coverage, complex terrain and constantly changing working environments require dependable communications between field personnel, vehicles, dispatch teams and emergency responders.

Mining operations can extend across open pits, underground workings, transportation routes and processing facilities, often covering large areas with significant variations in terrain and operating conditions. These environments can create challenges for radio communications, while changing work locations and the movement of personnel and vehicles can make maintaining consistent connectivity particularly demanding.

The mining group required a communications solution capable of connecting geographically dispersed operational areas while providing centralised coordination and supporting rapid response when incidents occur. Caltta and Radiocom implemented a multisite DMR ECS architecture to address these requirements.

The network connects separate mining areas through an IP-based infrastructure, enabling communications resources to be coordinated across sites while providing a scalable foundation for future expansion. Rather than relying on isolated communications channels, the deployed solution brings together field radio communications and centralised dispatch capabilities.

The network supports voice communications for mobile and field personnel, while the PD200 dispatch platform provides the control centre with real-time GPS location information, call recording and operational event logging. This gives dispatch teams greater visibility of personnel and vehicles and enables resources to be coordinated more efficiently across the mining operation.

Caltta’s PR900 digital repeaters form the network infrastructure supporting communications coverage, while PM790 mobile radios are used by transport and patrol teams and PH690 portable radios support personnel working in demanding field environments. Features including AI-based noise cancellation, emergency calling and man-down alerts provide additional operational and personnel-safety capabilities. The ECS architecture also incorporates dynamic channel allocation and load balancing to help manage network resources and reduce the potential for communications congestion.

A key consideration for the project was the ability to support the mining group’s future operational development. Because the individual sites are interconnected through IP networking, additional mining areas, shafts, pits or processing facilities can be incorporated into the communications architecture as operations expand. This provides the operator with a scalable communications foundation without requiring a fundamental redesign of the network, while also enabling communications infrastructure to evolve alongside the mine.

Radiocom Holding Group played an important role in the successful delivery of the project, providing local market knowledge, project support and implementation expertise in Uzbekistan.

“Successful industrial communications projects depend not only on technology, but also on a strong understanding of the local operating environment and the customer’s day-to-day requirements,” said Djabbarov Mirvakhid, Managing Director of Radiocom Holding Group. “Our collaboration with Caltta enabled us to combine local expertise with an established DMR communications platform to deliver a practical solution for a demanding mining environment.”

The project has strengthened the cooperation between Caltta and Radiocom Holding Group and created a foundation for further opportunities across Uzbekistan’s mining, energy and heavy-industry sectors. It also highlights the role of modern DMR infrastructure in strengthening operational coordination and communications resilience in challenging environments.

“Reliable communications are fundamental to safe and efficient mining operations, particularly where teams and vehicles are distributed across large and complex sites,” said Leo Li, Head of Channel Business at Caltta Technologies. “This project demonstrates our ability to combine proven DMR technology with local expertise to deliver a communications network that can adapt to the operational realities of the mining industry.

“We are pleased to work with Radiocom Holding Group to support the continued digitalisation of industrial communications in Uzbekistan.”
