Increasing accuracy of bluetooth low energy for distance measurement applications

Bluetooth Low Energy (BLE) or Bluetooth Smart is a wireless device that can be connected to many wireless devices with many applications. In this paper, we analyzed the accuracy of BLE for measuring distance in order to build the indoor positioning application. The problem of BLE in distance measurement and indoor position are low accuracy that is caused by the fading effect. We discussed about the effect of changing the value of advertising interval to the accuracy of distance measurement by application, between BLE as a Transmitter and a Smartphone with Android OS as a receiver. The result showed that the accuracy of distance measurement will increase if the value of advertising interval is decreased.
