Descriptions
01
Power levels
The power levels are calculated by adding the power required for transmitting the signals, and the energy of the detector is used
02
Duty cycle
: on-time intervals; : off-time intervals
03
Distance
indicates power of the signal (dBm) in the zero distance, indicates signal power (dBm) in the distance , indicates the signal frequency (MHz), indicates fade margin, and refers to the path-loss exponent
