An engineer is adding APs to an existing VoWLAN to allow for location based services. Which option will the primary change be to the network?

The correct answer is B. AP footprint. Location-based services require that at least three APs can simultaneously hear any given device at a usable RSSI level so the location engine can triangulate its position. This typically demands a denser AP deployment than a voice-only WLAN. The primary change is therefore the…

Explanation

Location-based services require that at least three APs can simultaneously hear any given device at a usable RSSI level so the location engine can triangulate its position. This typically demands a denser AP deployment than a voice-only WLAN. The primary change is therefore the AP footprint - more APs must be added and repositioned to achieve the necessary overlapping coverage density. Cell overlap does not decrease (it actually increases). Transmit power would more likely decrease (smaller cells for better granularity), not increase. Bridging and triangulation are architectural concepts, not changes the engineer makes to the network itself.
