Exam 400-351 topic 2 question 4 discussion

You are designing a wireless network for a museum. One of their requirements is to track people inside the museum and push a notification into their tablet device as soon as they step in front of the painting with information about the artist and the painting. This information must be delivered in real time. You are using regular probe request-based tracking and, during testing, you notice that although the tablet is connected to the museum Wi-Fi network, the location is not updating in real time as you move. It can take almost two minutes for the location to be updated. Which option is the likely reason for this issue?
