Network architecture design

As part of a project to modernize a sports stadium and enhance the customer-service experience for fans, the stadium owners plan to implement a new wireless system. Currently, all tickets are electronic and are managed through the stadium mobile application. The new solution must enable location tracking of fans with precision within 5 ft (1.5 m) to provide 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?

Explanation

Bluetooth Low Energy (BLE) supports low-power proximity sensors and indoor-positioning deployments, enabling a mobile application to infer a fan’s location from nearby BLE beacons. This provides the fine-grained proximity tracking needed for stadium services such as assistance dispatch, location-based ordering, effects, and identifying a raffle winner. An SSID is only a Wi-Fi network identifier, NFC is intended for extremely short-range interactions, and IoT is a general device category rather than a location-tracking technology.
