Overcoming the Challenges of 4G LTE and MIMO for In-Tunnel Wireless Connectivity

As mobile wireless continues to make the transition to data and video-dominated broadband, unprecedented demands are being placed on operator networks. Thus, 4G LTE networks are deplored worldwide - mainly in macro environments - to support this increasing data throughput demand for mobile users everywhere. However, specifically for in-tunnel applications, deployment of 4G networks has just started.

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