  2. 2. Cost-Effective Positioning based on WiFi-Probes: A Quantitative Study : Deriving the Position of a Smartphone using the Signal Strength of WiFi-Probes

    University essay from Blekinge Tekniska Högskola/Institutionen för datalogi och datorsystemteknik; Blekinge Tekniska Högskola/Institutionen för datalogi och datorsystemteknik

    Author : Alexander Ljung; Hannes Knutsson; [2018]
    Keywords : WiFi; Probe Broadcast; Local Positioning System; Trilateration; RSSI;

    Abstract : In the modern society, almost everyone has a smartphone. These devices tend to almost always use WiFi-networking. For the device to identify nearby WiFi access points it has to send out WiFi probing broadcasts. Nearby access points respond to these broadcasts in order to let the device know that they are within reach. READ MORE

  3. 3. Methods for locating signal jammers with a UAV

    University essay from Linköpings universitet/Fysik och elektroteknikLinköpings universitet/Tekniska fakulteten; Linköpings universitet/Fysik och elektroteknikLinköpings universitet/Tekniska fakulteten

    Author : Andreas Höggren; Love Lindmark; [2018]
    Keywords : UAV; Signal jammer; RSSI; Signal reflection;

    Abstract : Wireless communication today is a modern way to transport data from one location to another. One of the drawbacks of this feature is that a signal jammer can disrupt communications between the receiver and transmitter since the radio waves travel in the open air. This drawback can be exploited in both military and civilian applications. READ MORE

  4. 4. A Combination method of Fingerprint Positioning and Propagation Model Based localization scheme in 3D Large-Scale Indoor Space

    University essay from Mittuniversitetet/Avdelningen för informationssystem och -teknologi

    Author : Jun Liu; [2018]
    Keywords : ;

    Abstract : To achieve the concrete aim of improving the positioning accuracy for large-scale indoor space in this thesis, we propose a weighted Gaussian and Mean hybrid filter (G-M filter) to obtain the G-M mean of received signal strength indicator (RSSI) measurements, which is implemented by taking the practically experimental measurements of received signal strength indicator and analyzing the characteristics of received signal strength indicator. Meanwhile, various path loss models have been utilized to estimate the separation between the transmitting antenna and the receiver (T-R separation) by calculating the G-M mean of received signal strength indicator, therefore, a dynamic-parameter path loss model has been proposed which can be appropriate to enhance the accuracy of estimated T-R separation and accurately describe the indoor position.
