Critical and crisis communications
When you really need to communicate, the radios really need to work. cellXica’s high performance, high-reliability mobile networks perform every time.
We work closely with organisations which design, build or operate critical and crisis communications infrastructure and services.
Our clients are typically specialist connectivity providers, expert system integrators and dedicated suppliers to the emergency services. Each is focused on solving mission-critical problems, irrespective of operational circumstances, physical location or environment. They trust us to design and deliver integrated system solutions that meet their needs, exceed their expectations and improve operational outcomes.
The emergency services, specialist response teams and public safety officials all rely on access to fast, reliable voice and data services, often at times when public networks are overwhelmed, and in places where no existing connectivity is available.
Cellular radio technologies form the backbone of the portable, resilient and secure communication solutions relied on by the organisations responsible for managing critical incidents.
- Private cellular networks ensure first responders and coordinating authorities have access to stable, uninterrupted communications, irrespective of public network service levels
- Portable LTE and 5G networks can be deployed quickly via vehicle-mounted base stations, with integrated satellite uplink adding external internet connectivity
- First responders, field personnel, and mobile command units remain connected in real time across wide areas, enabling coordination of teams, vehicles, drones, and sensors without signal dropouts
- 5G and LTE networks support low-latency voice, video, and data transmission for real-time situational awareness, live video feeds and remote command control
