Analysis of positioning accuracy corresponding to the number of BLE beacons in indoor positioning system

摘要: In these days, a technology that utilize of Bluetooth Low Energy (BLE) beacon, has been attracted attention to provide variety convenience services. Especially, not limited the service can assist people directly such as public safety, healthcare, proximity-based service, mobile payment, etc., indirectly asset tracking also proposed. Most all, indoor location awareness using BLE beacon is essential technique realize services, it expected be more focused if spread in future. this paper, we first analyse practical path loss model signals with compared Wi-Fi order take advantage for positioning. To estimate model, employed four beacons (each two same manufacturer) and AP. Each signal was measured during one minute at each reference distance from lm 13m (with 2m interval) Line-of-Sight (LOS) environment. The calculated used generate virtually, applied configure radiomap positioning measurement data our simulation. Since relatively lower tx power APs, requires much achieve comparable accuracy. We on relationship between number installed its accuracy paper.
