Indoor location is finally beginning to deliver on promises made over the last decade. Low cost deployment using simple, power efficient sensors is driving this development. This presentation will provide a survey of mobile location technologies that employ the Bluetooth Low Energy standard paired with the capabilites of recent mobile devices. After moving on to consider the cross platform capabilities of recent vendor protocols, the talk will weigh the pros and cons of various uses of triangulation, proximity and hybrid GPS/Wifi/Bluetooth in location applications. Finally, a live demo of proximity, ranging and position using Bluetooth Low Energy devices and the iBeacon protocol will be conducted within the presentation room.
