Probability of OFDM Signal Interception in eHealth Applications

The main purpose of the research conducted in this field is to improve senior’s Quality of Life using remote monitoring systems. One of the main problems of these remote systems is the sensitive personal/medical data security. As in different field of e-Health, like telemedicine, where a high data rate is requested, OFDM systems represent a suitable candidate for these areas. This paper focus is to analyze the probability of intercept (POI) for OFDM (Orthogonal Frequency Division Multiplexing) communication systems. A number of measurements are performed using a WiMAX communication signal. The measurements were conducted using two broadband spectrum analyzers and the conclusions are that the POI, for these systems, is proportional with the number of parallel receiver channels and the scanning speed of the receivers.
