An engineer is planning for a 24 Mbps data rate 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

225ft
225 ft for 24mbps.
A
The correct answer according to the Cisco Site Survey Guidelines for WLAN Deployment
Understand Wireless Data Rates is 225 ft.
Wireless data rate configurations are one of the most critical tools available to tune and optimize wireless networks. The choice of data rate directly impacts coverage and performance; therefore, it is essential to understand how changes to data rates impact an environment.
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.
