1. Multipath propagation
Transmitted signals can combine with reflected ones to corrupt the signal
detected by the receiver. The PATH between two antennas is a straight line as
shown in Figure 3-2. Any obstacle in this PATH can redirect parts of the
transmitted signal as shown in Figure 3-3. The best propagation path is a clear
line of sight with good clearance between the PATH and any physical obstacle.
