Tunnel Coverage

Tunnel Coverage Concepts and Disadvantages of alternatives to Radiating Cable:

Traditional Antenna based in-tunnel coverage solutions are possible, however those solution comes with  significant drawbacks such as:

• Poor coverage due to elevation contour of the tunnel

• Signal blockage by trains

• Signal blockage by curves (e.g. metro)

• Challenging system design particularly for receiving antennas located inside the train

• Sizes becomes a critical parameter notably for mission critical applications at lower frequencies

• Antenna based solutions do not provide the required system reliability and availability - particularly in 4G / 5G capacity driven communication systems

Advantages of Radiating Cable for Tunnels:

C&C Universal Engineering Sdn Bhd’s Tunnel Solutions employs RADIAFLEX Radiating Cables which is the industry’s most advanced portfolio of 4G / 5G-ready radiating cables for wireless indoor communications. RADIAFLEX radiating cables:

• Support all services up to 6 GHz with high performance, making them ideal for multiband, multi-operator applications in the most challenging indoor and underground environments

• Can be combined to take advantage of 3.5 GHz spectrum and accelerate to 5G in buildings and tunnels

Support for any Application:

RADIAFLEX radiating cables are available in several families with different bending radii, performance levels and outer conductor types to meet any application requirements:

• In-building and in-tunnel applications that require the highest possible radiating cable performance to support throughput-optimized 5G coverage solutions and the highly reliable systems needed for mission-critical wireless communications

• Heavy-duty in-building and mining applications

• In-vehicle applications

• Plenum-rated installations
