Why does a frame transmitted at 1 Mbps have a greater usable range than the same frame transmitted at
54 Mbps?
A.
Free space path loss causes greater signal dispersion for higher rate transmissions.
B.
Receiver sensitivity requirements are lower for frames transmitted with less complex modulation and
coding.
C.
To improve reliability, 802.11 STAs increase transmit power as the signaling rate decreases.
D.
Lower data rate RF transmissions travel at higher speeds and are less likely to experience collisions.
E.
Frames sent at higher data rates are also sent at higher power levels and are therefore more prone to
collisions and multipath.
