As the Rio 2016 Olympics unfold, RIOgaleão Airport has had to accommodate an unprecedented number of travelers. A network of 3,000 newly installed beacons and a complementary app with wayfinding features are guiding Olympic hopefuls and supporters through the airport’s recently unveiled South Pier, a 100,000-square-meter extension to Terminal 2. Cathay Pacific’s flagship first- and business-class lounge at San Francisco International Airport offers visitors more than just a taste of Hong Kong. The choice between dan dan mian or fish ball noodle soup and more at the carrier’s signature noodle bar, or fresh daily menus from the deli counter, the self-service buffet or the Italian coffee bar, is enough to overwhelm even the most ravenous of travelers. So, to help the hungry choose their fare, Cathay enlisted beacon technology.
