  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
