RADIAFLEX® Redeployable System Lifetime Connectivity

PORTABLE TETRA COVERAGE FOR TEMPORARY AND EMERGENCY OPERATIONS

Where Communication Cannot Fail Modern buildings and underground infrastructure create significant challenges for emergency communications.

Dense concrete cores and steel reinforcement in high-rise construction or in underground transport systems create a ‘Faraday cage’ effect that causes signal attenuation and unpredictable coverage.

Emergency services and infrastructure operators need a way to maintain reliable coverage across these environments, which is a considerable operational challenge.

About TETRA TETRA is the radio communications system used by emergency services for reliable operational communication in difficult environments. Specifically designed for emergency communication, it is effective in environments where standard coverage can be unreliable.

Operating within the 430 MHz and 870 MHz frequency bands, it offers multiple technical advantages: •

Superior penetration through concrete, steel and underground structures

•

Enhanced diffraction, allowing signals to bend around obstacles and into coverage shadow areas

•

•

Reduced infrastructure dependency during operational incidents

•

Reliable vertical and underground propagation in complex structures

•

Optimized for reliable, low latency, mission-critical voice services

Whether operating in reinforced high-rise buildings, below ground in transport infrastructure, or across difficult terrain, TETRA can deliver the stability and continuity required for tough operational conditions.

But what happens in buildings without existing TETRA coverage?

RADIAFLEX® Redeployable (RD) System

System Characteristics

The RADIAFLEX RD System is a

• Continuous radiating cable for reliable coverage up to 600m

portable TETRA communications network for rapid deployment during emergencies, regardless of environment or existing infrastructure.

Developed initially for emergency services, RFS radiating cable is deployed from a portable drum and functions as a continuous distributed antenna. The result is consistent coverage without repeater infrastructure that can be redeployed as required.
