Reason for Location Update Delay in Museum Wi-Fi Tracking
Question
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?

The issue of location tracking delays in a wireless network for a museum, specifically with regard to tracking people in real time and pushing notifications to their tablets, can be caused by a number of factors. One possible reason is that probe request-based tracking, which is being used to track the location of the devices, may be bound to delay due to the broadcast type of traffic that is not acknowledged over the air and could be lost. This means that the wireless network may not receive the probe requests from the devices or may receive them late, which would affect the accuracy and timeliness of the location updates.
Another possible reason for the delay in location updates is that the CCXv4 S60 feature, which is designed to carry out location updates more frequently, may be disabled by default. CCXv4 S60 is compatible with all Wi-Fi clients and can help improve the accuracy and timeliness of location updates. Therefore, enabling this feature may help resolve the issue of delayed location updates.
It is also possible that the Cisco MSE (Mobility Services Engine), which is used to calculate the location of devices in the wireless network, may not perform a new location calculation for certain elements if the resulting position is not at least 5 meters different than the previous location. This could cause delays in updating the location of the devices, particularly if they are moving around within a small area.
Finally, probe request-based tracking is device dependent, and the tablet might not send a probe request if it is maintaining a good Wi-Fi signal. This can cause slower location updates, as the wireless network may not receive the necessary information to update the location of the device in real time.
In conclusion, the issue of delayed location updates in a wireless network for a museum can be caused by a variety of factors, including the type of location tracking used, the settings of the wireless network, the configuration of the Cisco MSE, and the behavior of the devices themselves. A detailed analysis of these factors is necessary to determine the root cause of the issue and to implement an effective solution.
