This research focused on distance measurement using Received Signal Strength Indicator (RSSl) that utilizing Pythagoras theory to get the position of a smartphone with the help of 4 Access Point (AP) in indoor environment. There were many research have been done in this area, but the issue is about the accuracy. From studies that have been done before, there are differences between the results of...
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...
