A new dataset has been added to CRAWDAD. <http://crawdad.org/init/robotarm/> Time- and frequency-variant 2.4 GHz ISM band channel gain Contributed by Dimitri Block, Niels Hendrik Fliedner, Daniel Toews, Uwe Meier. The time- and frequency-variant channel gain is measured in the presence of an industrial cyclic moving robot arm obstacle for four coexisting wireless nodes for the whole license-free 2.4-GHz-ISM band with a time- and frequency-resolution of 110 microsseconds and 1 MHz, respectively. Results for two links are given.
