چکیده
For railway and metro operators, offering a 4G network connection is becoming more critical to keep up with passenger demands for continuous access to data and mobile services while they are on the move. As a result Radio Frequency Systems (RFS) conducted a comprehensive measurement campaign focusing on in‐tunnel LTE performance based on its Radiaflex radiating, or leaky feeder, cables to review the design challenges for in‐tunnel LTE applications and to analyse key performance indicators (KPIs).
