If you’ve ever tried to stream a video on your mobile device while traveling by train, you may be familiar with the sense of dread that tunnels inspire: right in the middle of watching your show, the video is interrupted because the mobile signal can’t penetrate through the tunnel and into the train. This frustrating experience may soon be a thing of the past—in Norway, at least.

Mobile operators there recently worked with Germany-based Radio Frequency Systems (RFS)—a designer and manufacturer of cable, antenna, and tower systems—to break the record for in-tunnel download speeds for a mobile network.
