RF in this context is Radio Frequency. It is a generalized term that includes a huge swath of the electromagnetic radiation spectrum. Bluetooth uses the 2.4 gigahertz band which IS a Radio Frequency.
RF includes all things radio. WiFi, Cellular, AM, FM (broadcast bands), TV, Radar, GPS, garage door openers, police radar, etc, etc.
" Radio frequency (RF) is a measurement representing the oscillation rate of electromagnetic radiation spectrum, or electromagnetic radio waves, from frequencies ranging from 300 GHz to as low as 9 kHz."
So, RF is not (only) Bluetooth, but Bluetooth IS a protocol that totally depends on RF.
Just curious, if you believe that Bluetooth does not use RF and cannot be labeled as using RF, what is your definition of RF?
How do you think Bluetooth transmits and receives data?
The reason I commented at all is that I was helping a friend configure a new printer. The manual actually had instructions for Bluetooth and RF setup. The poor guy was real confused until I explained that RF meant WiFi in this stupidly written chinglish manual. No need to confuse others when we can avoid it.
I am following this thread as I am close to buying a new Shield. I probably will once they iron out some of the bugs being discussed here.
