There’s an interesting article at code4lib on Creation of a Library Tour Application for Mobile Equipment using iBeacon Technology by Virginia Tech. It describes a project where a QR code driven library tour was updated to use beacons.
Some insights include how attractive beacons can become ‘lost’, the problem of replacing batteries, limited battery life due to the iOS requirement for beacons to advertise every 100ms and challenges physically fixing beacons.
As mentioned in our article on Choosing an Advertising Interval, it’s possible to set the advertising interval to between 300ms and 600ms while maintaining a reasonable detection time. Also, had the library chosen Android tablets they could have used a much longer advertising interval. 100ms is an artificial thing set by Apple for very quick detection on iOS devices. On Android, the scanning is more controllable,you can scan for longer and hence have beacons that advertise less often and have much longer battery life.
