Abstract
Bluetooth Low Energy (BLE) is a Bluetooth standard with low energy consumption. Beacons using BLE transmit BLE signals, which can be received by smart phones running iOS or Android OS. At present, demonstration experiments are conducted.
An indoor position detection using an ordered order-k Voronoi diagram was proposed. Beacons were installed in a building of Tokai University. Experiments are conducted to investigate position detection using the proposed approach. We have two results using the proposed system: (1) a floor decision success rate of 99.6 %; and (2) indoor position detection success rates of 85.5 % (first neighbor) and 48.9 % (second neighbor). Finally, we present some ideas for improving the proposed approach.

Notes
- 1.
Immediate, Near, Far and Unknown are the return values for a method in the iOS SDK.
- 2.
Two Voronoi polygons are adjacent when the polygons share a segment.
