An engineer is planning for a 24 Mbps data rate on the 5Ghz band for a new installation.
What is the coverage area from the AP if the environment and other factors are not taken into consideration?
A . 225 feet
B . 80 feet
C . 150 feet
D . 100 feet
Answer: A
Explanation:
Coverage (Cell Size)
Lower data rates can be demodulated across greater distances than higher data rates. This is because of the lower complexity encoding schemes ― the signal can be understood at a lower SNR. Enable lower data rates in order to increase the effective range of the AP; disable the lower data rates in order to decrease the effective range of the AP.
