Placement of sensors
As wifi accuracy is limited, we recognize that placement of the sensors at strategic spots is crucial in maximizing accuracy. However current sensors in the NTU Virtus Lab are placed as shown in the diagram below
You may have observed that there are 5 sensors ( as only 5 sensors were provided to them ) and they are located randomly ( locations where power supply is available )
If the placement of the current set up does affect accuracy, then it would not be fully utilized for energy conservation under normal circumstances and locating occupants in an emergency. This may also mean additionally costs for running redundant sensors.

Inability to communicate with occupants
While the current system is allows the admins to locate occupants, there is no way of communicating with them during an emergency. Making phone calls is not practical as they might be too many occupants in the building. Even if there are fire alarms to inform occupants about an emergency, they might not know what to do and where to go
