  1. 26. Evaluating LoRa Physical as a Radio Link Technology for use in a Remote-Controlled Electric Switch System for a Network Bridge Radio-Node

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Abdullahi Aden Hassan; Rasmus Karlsson Källqvist; [2019]
    Keywords : LoRa; Emergency preparedness; Amateur radio; System design; Embedded system; Radio electronics; LoRa; Krisberedskap; Amatörradio; Systemdesign; Inbyggda system; Radioelektronik;

    Abstract : This report explores the design of a system for remotely switching electronics on and off within a range of at least 15 km, to be used with battery driven radio nodes for outdoor Wi-Fi network bridging. The application of the network bridges are connecting to remote networks, should Internet infrastructure fail during an emergency. READ MORE

  3. 27. Communications solution for refugee settlement : Investigation of nRF24L01+ modules for use in a communications network

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Martin Engquist; Simon Bethdavid; [2018]
    Keywords : communications solution; refugee settlement; nrf24l01 ; nrf24l01; 2.4 ghz; frequency; transceiver module; arduino; microcontroller; bidi bidi; uganda; south sudan; uppsala university; radio;

    Abstract : The main purpose of this thesis is to test a communications solution for the second to largest refugee settlement in the world, Bidi Bidi. A solution where it is possible to inform the refugees with necessary information, for example that the water at a specific location is currently contaminated or that food is provided at another location.

    Abstract : The process of finding a parking space can be a tedious task that drivers spent too much time on today. With the rising threat from global warming, reducing the time spent driving is vital. READ MORE

  5. 29. Phase Locked Loops in Fully Integrated NB-IoT Transceivers

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

    Author : Adam Waks; [2018]
    Keywords : Phase locked loops; Narrow Band Internet of Things; Frequency pulling; Balun; Inductor; Technology and Engineering;

    Abstract : This thesis investigates how to fulfill the Narrow Band - Internet of Things (NB-IoT) specification for a fully integrated transceiver in the phase locked loop's (PLL) perspective. Designing a fully integrated transceiver, integrating a power amplifier (PA) is challenging as it leads to frequency pulling of the voltage controlled oscillator (VCO) in the PLL, deteriorating the performance.
