Here is a Business Insider article about beacons. The article focuses mainly on Apple’s iBeacon system, and it also focuses completely on the retail consumer “location-triggered notification” uses for Bluetooth low energy (BLE) technologies rather than the B2B staff tracking, asset tracking and other more creative potential uses.

However, the article is a nice very quick introduction to some of the very basic BLE beacon concepts. Also, it has useful and informative links to a lot of other resources. Enjoy!
