Mobile wireless makes the transition to data and video-dominated broadband. Unprecedented demands are placed on operator networks. Thus, 4G LTE networks are deployed worldwide mainly in macro environments to serve the increasing demand of data throughput for all kinds of mobile users at any places. However, specifically for in-tunnel applications, deployment of 4G network has just started.

The purpose of this white paper is to review the design challenges for in-tunnel LTE applications and to analyze the key performance indicators. The document summarizes the results of a comprehensive measurement campaign focusing on in-tunnel LTE performance based on RFS RADIAFLEX® radiating cables.

Furthermore, a number of test cases have been executed to investigate the applicability of MIMO technology in tunnel environments and to identify its individual requirements.

The white paper gives insight to the individual test configurations as well as the results which have been achieved.
