CWDP-305 · Question #76
Why does a frame transmitted at 1 Mbps have a greater usable range than the same frame transmitted at 54 Mbps?
The correct answer is B. Receiver sensitivity requirements are lower for frames transmitted with less complex modulation. See the full explanation below for the reasoning.
Question
Why does a frame transmitted at 1 Mbps have a greater usable range than the same frame transmitted at 54 Mbps?
Options
- AFree space path loss causes greater signal dispersion for higher rate transmissions.
- BReceiver sensitivity requirements are lower for frames transmitted with less complex modulation
- CTo improve reliability, 802.11 STAs increase transmit power as the signaling rate decreases.
- DLower data rate RF transmissions travel at higher speeds and are less likely to experience
