1. 1. Wi-Fi fingerprinting as a mean to measure building occupancy : A case study in an office environment

   Master-uppsats, KTH/Transportplanering

   Författare :Johan Bexhorn; Karl Kvarnefalk; [2023]
   Nyckelord :Wi-Fi tracking systems; Wi-Fi fingerprinting; footfall analytics;

   Sammanfattning : The task of collecting visitor data in an indoor environment and therein determining the occupancy of a building is an extensive task. Conventional methods are expensive, time-consuming, and often lack the ability to produce data in longer time series. Further, they often require disruption of the studied area as equipment must be deployed. LÄS MER

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

   Författare :HongShuo Yi; Duosi Dai; [2023]
   Nyckelord :LoRa; Indoor IoT Internet of Things ; Signal strength; Round-trip time RTT ; Goodput; LoRaWAN device classes; AVR-RSS2; RIOT-OS; LoRa; Inomhus-IoT Internet of Things ; Signalstyrka; Rundresa-tid RTT ; Goodput; LoRaWAN klasser; AVR-RSS2; RIOT-OS;

   Sammanfattning : This thesis is dedicated to measuring the communication performance of LoRa technology in an indoor environment and providing insight into its potential application as an effective Internet of Things (IoT) communication solution in Low Power Wide Area Networks (LPWAN). Through careful experimentation and analysis, we assessed various transmission parameters such as spreading factor (SF), bandwidth (BW), Payload Length (PL), and LoRaWAN classes. LÄS MER

5. 4. Ray-tracing Based Investigations on the Deployment of RISs in Indoor Scenarios

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

   Författare :Swaroop Divya Sai Prem Nambala; Dexin Kong; [2023]
   Nyckelord :Reconfigurable intelligent surface; RIS; optimization; Ray-tracing; Mixed integer linear programming MILP ; Complex impulse response; Wireless Insite.; Technology and Engineering;

   Sammanfattning : Reconfigurable intelligence surface (RIS) is a promising candidate technology for future 6G wireless communication systems. In existing communication systems, the network operators are unable to control the propagation environment, which causes significant limitations on communication performance. LÄS MER

7. 5. Machine Learning-based MIMO Indoor Positioning

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

   Författare :Qiyi Chen; [2023]
   Nyckelord :Technology and Engineering;

   Sammanfattning : The most widely used positioning system is Global Navigation Satellite System (GNSS), which uses traditional positioning techniques and cannot achieve satisfactory positioning performance in indoor scenarios due to Non-Line-of-Sight (NLoS) transmission. Fingerprinting is a non-traditional positioning technique that is robust to NLoS transmission in indoor scenarios. LÄS MER
