Question
As part of a project to modernize a sports stadium and improve the customer service experience for fans, the stadium owners want to implement a new wireless system. Currently, all tickets are electronic and managed by the stadium mobile application. The new solution is required to allow location tracking precision within 5ft (1.5m) of fans to deliver the following services:
- Emergency/security assistance
- Mobile food order
- Event special effects
- Raffle winner location displayed on the giant stadium screen
Which of the following technologies enables location tracking?
Options
- ASSID
- BBLE
- CNFC
- DIoT

Explanation
BLE (Bluetooth Low Energy) beacons deployed throughout the stadium enable indoor positioning with accuracy in the 1–3 meter range, meeting the required 5ft (1.5m) precision threshold. BLE beacons broadcast signals that are received by the stadium's mobile app on fans' phones; the app uses RSSI triangulation or angle-of-arrival techniques to calculate precise location. This makes services like emergency assistance, food delivery routing, and raffle winner locating on a screen feasible. SSID (A) is simply a Wi-Fi network name, not a tracking mechanism. NFC (C) has a range of only ~4cm and requires the device to be tapped - not suitable for continuous passive tracking. IoT (D) is a broad ecosystem category, not a specific location-tracking technology.
