Seeking to find the fastest way to the Olympics? Now travelers going to Brazil for the worldwide competitions can get directions via beacons. Rio de Janeiro’s Galeão International Airport recently launched a mobile app and beacons to aid the travelers headed to the city for the Summer Olympic Games, which run Aug. 5-21. Beacons are small pieces of hardware that can determine a traveler’s location via Bluetooth. In order for beacons to work, a traveler has to download the RIOgaleão Airport app and turn on the Bluetooth feature on her smartphone. The RIOgaleão Airport deployed 3,000 beacons across its 100,000-square-meter building, says Alexandre Villeroy, chief information officer at RIOgaleão Airport. The beacons work in conjunction with the mobile app to give travelers turn-by-turn directions around the airport.
