Siemens enhances cell phone reception in trains thanks to window pane solution
Researchers in Vienna have developed special high-frequency window panes for trains
Massive improvement in receiving level for mobile terminal devices in trains
Greater convenience and better travel quality
It often takes a lot of patience to surf the Internet when traveling by train. Even in high-speed trains, the success rate for displaying Internet pages varies between just 41 and 65 percent, depending on the network provider. The window panes on the trains are an obstacle to good mobile reception. Their coating protects passengers against heat and sun, but the downside of this is that they reflect not only thermal or solar radiation but also all other electromagnetic waves, effectively turning the carriage into a Faraday cage. The shielding on high-speed trains is 99.9 percent. Researchers at Siemens have now come up with a frequency-selective coating for window panes that solves this problem.
