RFID Spectrum Regulation

Globally, there are regulatory bodies to define the frequency ban and spacing, radiated power and spurious emissions etc. As such, a signal to a device in America may turn out to be noise in another device in Europe. Thus, we should take this into consideration when working on RFID projects to be adapted on a global basis.

Country	Frequency Band (MHz)	Power	Technique
