With Cyton/Bluetooth Cyton/Wifi, what are the highest frequencies that one can expect to be measured reliably and without (much) artifacts from sampling or transmissions?

Which is basically saying that sample rate needs to be twice the highest frequency you are digitizing. HOWEVER, that guideline is still subject to 'aliasing' artifacts.

The Wifi Shield board is not currently available, but is 'planned' to be manufactured again, once some power supply issues are resolved.
