Abb.	meaning	Notes
ASK	Amplitude Shift Keying	Keying 0's and 1's by altering the radio carriers amplitude
FSK	Frequency Shift Keying	Keying 0's and 1's by altering the radio carriers frequency
PSK	Phase Shift Keying	Keying 0's and 1's by altering the radio carriers phase
MPSK	Multiple Phase Shift Keying	Keying more than one bit at a time by using four or more phases
RF	Radio Frequency	Rate of oscillation in the range of around 3 kHz to 300 GHz corresponding to radio waves
FSPL	Free Space Path Loss	Loss of amplitude of the signal in free space over distance
ISI	Intersymbol Interference	Signal misinterpreted by receiver due to multipath signals out of phase
EIRP	Equivalent isotropically radiated power	The highest RF signal strength transmitted from a particular antenna. Often expressed in dBm	RSSI	Received Signal Strength Indicator	power level received by the receiver radio in dbm
mW	Milli Watt	0,001 Watt
dBm	Decibel milliwatt	Decibel relative to 1 mW of power.
dBi	Decibel isotropic	Antenna gain compared to a theoretical isotropic antenna
dBd	Decibel dipole	Antenna gain compared to a theoretical isotropic antenna. Add 2,14 dB to get dBi
