<p>The method involves providing an electromagnetic field from a current loop that extends along a longitudinal section of a railway track. Data that is to be transmitted is coupled into the current loop driven with a current source (IQ). The power source has an impedance (ZQ) that ranges between 20 and 100 k |. The current loop runs over a length of several hundred meters and is at least partially formed using a leaky cable arrangement. An independent claim is also included for a system for transmitting data between a rail-bound vehicle and a repeater.</p> |
