Overview

TandemIT provided programme leadership for a multi-year communications modernisation initiative across a nationally distributed public safety organisation operating complex operational environments. The programme involved replacing ageing analogue communications infrastructure with a modern digital communications platform while maintaining operational continuity and supporting frontline personnel across multiple locations. Scope included digital radio infrastructure, dispatch and control room systems, workforce safety and duress capability, location and beaconing technology, LTE-enabled communications services, subscriber devices and accessories, training and operational readiness, site-based deployments, and vendor and stakeholder management. The initiative represented a significant operational technology transformation delivered within a highly regulated environment where reliability, safety, and operational continuity were essential.
