Abstract :
The performance of wireless sensor nodes operating in the 2.40-2.48 GHz ISM frequency band is presented over each of the 16 different channels. It is shown that the response of individual carrier frequency depends on both the antenna and the overall system. On-body channel characterization is performed at various points on the human body torso in an anechoic chamber using a pair of wireless sensor modules. Measurement results are compared with those from the conventional technique with a Vector Network Analyzer.
