A method for monitoring a danger area of a railway installation. At least one radio module is arranged in, or in the vicinity of, the danger area. Radio signals are transmitted by the radio module and the radio signals are received and evaluated. A pattern of the received radio signals in a basic state of the danger area is determined and when the radio signals are evaluated, differences from the pattern in the basic state are determined and a response is triggered when the differences exceed a predefined limit value. There is also described a monitoring device. The radio modules are preferably WLAN modules and the danger area is a tunnel. Timetabled breaches of the danger area by trains do not lead to an alarm and the radio modules are functionally tested by determining whether the predefined limit value is exceeded when a train travels through.
