1. 16. Indoor Positioning System based on Bluetooth Low Energy for Blind or Visually Impaired Users : Running on a smartphone

   University essay from KTH/Radio Systems Laboratory (RS Lab)

   Author : Tengqingqing Ge; [2015]
   Keywords : RSSI-based indoor positioning; Bluetooth; smartphone; blind and visually impaired; RSSI-baserade inomhuspositionering; Bluetooth; smartphone; blinda och synskadade;

   Abstract : Blind and visually impaired (BVI) users desire an indoor navigation tool that is inexpensive, convenient, and reliable. The purpose of this thesis is to examine the feasibility of using a smartphone as a platform for such a navigation tool. A good navigation tool should have both a good positioning accuracy and a user-friendly interface. READ MORE

3. 17. Evaluation of Ant's wireless protocol for indoor navigation with RSSI

   University essay from Mittuniversitetet/Avdelningen för elektronikkonstruktion

   Author : Patrick DuRussel II; [2014]
   Keywords : ANT; Wireless; Indoor Navigation; RSSI; Android;

   Abstract : Do we always have to be lost in the halls of a big school on an already stressful first day of class? This paper has evaluated a prototype indoor navigation system that uses a ANT wireless protocol. The protocol has been placed into nodes (small electrical devices, hardware) which are then placed around an area of interest (a map), like beacons, using RSSI (signal from the nodes) to help determine where the subject is located.

4. 18. An IEEE 802.15.4 Packet Error Classification Algorithm : Discriminating Between Multipath Fading and Attenuation and WLAN

   University essay from Mittuniversitetet/Avdelningen för informations- och kommunikationssystem

   Author : Nan Chen; [2014]
   Keywords : WSN; error discrimination; MFA; WLAN interference; F-BER; RSSI; LQI; CC2420;

   Abstract : In wireless sensor networks, communications are usually destroyed by signal attenuation, multipath fading and different kinds of interferences like WLAN and microwave oven interference. In order to build a stable wireless communication system, reactions like retransmission mechanisms are necessary. READ MORE

5. 19. "Characterization of RSSI based Proximity Detection"

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Dinesh Ramesh Kumar; [2013]
   Keywords : Localization technique; Propagation; pathloss; RFID;

   Abstract : Real Time Locating System (RTLS) is a widely used monitoring application that assists in tracking and identifying persons or any objects using Anchors(nodes), RF tags and WSN. This is simplified by using the Chirp Spread Spectrum (CSS) technology . READ MORE
