  1. 21. Realize Smart City Applications with LoRaWAN Network

    University essay from Mittuniversitetet/Avdelningen för elektronikkonstruktion

    Author : Bin Wang; [2019]
    Keywords : Smart City; IoT; WSN; LoRaWAN;

    Abstract : Internet of Things is an important part of realizing smart cities, this article introduces a proposal to build an Internet of Things system with LoRaWAN to achieve diverse smart city applications. There are three problems proposed and resolved in this research, how to maximize wireless devices’ lifetime with LoRa protocol characters， how to choose the gateways’ location for improving the efficiency and reduce costs, and about a good way to set up network servers to balance performance and consumption to implement in smart city applications.

  3. 22. Non-Coherent Radio-Based Positioning

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Farshid Rezaei; Mohamad Abou Nasa; [2019]
    Keywords : target localization and tracking; wireless sensor network WSN ; hybrid measurements; received signal strength RSS ; angle of arrival AoA ; Technology and Engineering;

    Abstract : In this thesis, a new Angle-of-Arrival (AoA) technique is used to determine the direction of a target in an outdoor environment using Radio Frequency (RF) signals. This technique estimates the AoA based on the difference between the Received Signal Strength Indicators (RSSI) from two/four directive antennas. READ MORE

  6. 25. UWB-based wireless sensor network with medical application

    University essay from Uppsala universitet/Signaler och System

    Author : Joakim Lindström; [2018]
    Keywords : ;

    Abstract : This master thesis aims to develop a prototype of a wireless sensor network (WSN) using ultra wideband (UWB) radio and communication. The WSN consists of five sensor nodes and one sink which is connected to an Android smartphone. The smartphone acts as a sensor data management unit and has the ability to display sensor measurements. READ MORE
