Shenzhen, China — 05 January 2026 — Caltta Technologies, a global provider of professional wireless communication solutions, has successfully deployed a Digital Mobile Radio (DMR) for a major national infrastructure construction project in the United Kingdom. The deployment of Enhanced Conventional System (ECS) was completed in close collaboration with Caltta’s local partner, JustCom.

Designed for large-scale, high-risk construction environments, the Caltta DMR ECS solution delivers flexible channel allocation, rapid emergency response, and elastic scalability. The system provides a secure, reliable, and low-latency communication network, enabling seamless coordination among hundreds of on-site personnel.

Meeting the Communication Demands of Large-Scale Infrastructure Construction

As a nationally significant infrastructure project with direct impact on economic development and public welfare, the construction site presents complex operational challenges. Multiple contractors, subcontractors, and safety teams operate simultaneously across a wide geographic area, requiring stable, real-time communication at all times.

The project environment is characterized by high safety risks and constantly changing conditions, making reliable coverage, high system capacity, and immediate emergency response essential to protecting workers and maintaining construction efficiency.

DMR ECS Solution Enables Reliable, Scalable, and Instant Communication

Caltta’s DMR ECS solution was selected to address these challenges through a combination of robust performance and intelligent system design. The system supports up to 50 simultaneous voice calls, allowing different teams to operate independently without congestion.

A key feature is the emergency all-call override, which can pull all radio users into a single channel within one second during critical incidents, ensuring rapid, site-wide coordination. In addition, the ECS architecture enables dynamic channel allocation, allowing the DMR network to scale in line with project requirements while maintaining uninterrupted service.

On-site personnel are equipped with rugged Caltta DMR radios, engineered for demanding construction environments and delivering clear digital audio, high durability, and extended battery life to support long working shifts.

Driving Safer, More Efficient Infrastructure Communications

“Having instant communication across the entire project is a game-changer,” said a representative from the project team. “The emergency all-call function gives us confidence that in any situation, we can reach every worker within seconds. Caltta and JustCom have delivered a solution that significantly improves both safety and operational efficiency.”

Andrew, the Sales Director of JustCom, added: “Caltta’s DMR ECS solution represents a strategic investment in the project’s long-term success. By prioritizing reliability, scalability, and safety, we have implemented a communication system that meets current needs while remaining adaptable to future challenges.”

Caltta values its collaboration with JustCom on this deployment, combining global technology expertise with strong local delivery capabilities. The DMR ECS solution sets a strong benchmark for reliable on-site communications in large-scale infrastructure projects.
