a. absorption f. fading
b. amplitude g. free space path loss
c. antenna h. Fresnel zone
d. chipping code i. hopping code
e. diffraction j. polarization
1/ a form of interference/power loss in which the signal is reflected or refracted by the atmosphere, ground, or other obstacles, and the reflected path interferes with the direct path
2/ a type of loss in which certain materials absorb the RF signal
3/ a device used to transmit or receive radio waves
4/ the sequence of changing frequencies in FHSS that determines the sequence and speed of frequency hops
5/ the loss of signal strength resulting from the dispersion of the signal over distance
6/ the bit pattern used in direct sequence spread spectrum
7/ the plane on which radio waves propagate, or the orientation of the radio waves as they leave the antenna
8/ an area in which you can determine RF signal strength, identify potential obstacles, and determine the potential for multipath distortion
9/ a phenomenon tin which a signal bends around objects in its path
10/ the maximum departure of a wave from its undisturbed state; the height of the carrier wave
