1. 6. IoT Buoy for Water Quality Monitoring : Design, prototype, and test of a solar-powered, LoRaWAN-based WQM system for the smart city

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Mattia Dalla Via; [2021]
   Nyckelord :IoT; LPWAN; Water Quality Monitoring; Environmental Monitoring; Smart City;

   Sammanfattning : Although water is incredibly abundant on Earth, only 2.5 % of the water reserve is freshwater, and one third of the world’s population lacks safe drinking water. Water quality monitoring (WQM) is thus a crucial asset to safeguard this invaluable resource. LÄS MER

3. 7. Information visualization of network parameters in private cellular network solutions

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Emma Åkesson; [2020]
   Nyckelord :Information visualization; 5G; private cellular networks; dashboards; dashboard design;

   Sammanfattning : In the upcoming years, industrial enterprises are expected to undergo a major transformation, as the Internet of Things (IoT) reaches widespread adoption. A key enabler behind this transformation, known as Industry 4.0, is the 5th generation of cellular networks (5G). LÄS MER

4. 8. An Energy Efficient Narrowband Internet of Things Radio Base Station

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Karl Minör; [2020]
   Nyckelord :Technology and Engineering;

   Sammanfattning : NB-IoT was designed as an add-on to the LTE standard to enable wide area cellular connectivity to low-cost devices to facilitate the rapid growth of the Internet of Things. NB-IoT was found to increase the idle power consumption of the radio unit in an example LTE radio base station by almost 17%, costing the mobile network operator not only money, but also harming the environment through increased CO2 emissions.
