Answer 1

We did use gimbal's ibeacons for indoor localization in a 6mx11m area. The RSSI fluctuation was a major issue that we handled through particle filtering. The code for the project can be found at https://github.com/ipapapa/IoT-MicroLocation/. The github repository contains the iOS application as well as a java based apache tomcat server. While we did get an accuracy as high as 0.97 meters, it is still very challenging to use beacons for micro-location purposes.Check the paper http://people.engr.ncsu.edu/ipapapa/Files/globecom2015.pdf which has been accepted for publication in IEEE Globecom conference.
