Abstract

Indoor Positioning has been an active research area in the last decade, but so far, commercial Indoor Positioning Systems (IPSs) have been sparse. The main obstacle towards widely available IPSs has been the lack of appropriate, low cost technologies, that enable indoor positioning. While Wi-Fi infrastructures are ubiquitous, consumer-oriented Wi- Fi enabled mobile phones have been missing. Conversely, while Bluetooth technology is present in the vastmajority of consumermobile phones,Bluetooth infrastructures have been missing. Bluetooth infrastructures have typically been installed as part of complete hardware-/software IPSs that often incur a substantial hardware cost. Furthermore, Bluetooth has low power consumption compared to Wi-Fi devices, which promotes longer battery life-time on mobile phones. In this paper, we present a Bluetooth IPS based entirely on commodity-grade products. The positioning accuracy is evaluated by using the so-called location fingerprinting technique which is well-known from Wi-Fi positioning literature. The results show that 2 meters median accuracy is achievable - a result that compares favourably to results for Wi-Fi based systems.
