Communication Range, defined as the maximum distance allowing a reliable radio link to exchange information between a transmitter and a receiver.
Even simple oscilloscopes are not designed to handle RF challenges as speciallized equipment, the right ONDUINO shield can enhance some of their capabilities...
Receiver sensitivity, typically measured in milliwatts, stands for the weakest power of the signal that can be reliably received and understood.
RF power, typically measured in milliwatts, refers to the strenght of the RF signal. Higher power cover greater distance and penetrate obstacles more effectively.
