The Wi-Fi signal strengths in indoor environments would be affected by various time-varying environmental factors (e.g. number of people, humidity and temperature). To tackle this problem, Dr Lu proposed one method in each category for wireless localisation in time-varying indoor environments. Both proposed methods give better localisation accuracy.<\/p><p style=\"text-align: justify;\"><\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-cbe960f elementor-widget elementor-widget-image\" data-id=\"cbe960f\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"elementor-image\">\n\t\t\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/www.hsu.edu.hk\/wp-content\/uploads\/2021\/05\/Photo-2-1.jpg\" data-elementor-open-lightbox=\"yes\" data-elementor-lightbox-title=\"Wireless Localisation in Time-Varying Indoor Environment\" data-elementor-lightbox-description=\"Wireless Localisation in Time-Varying Indoor Environment\">\n\t\t\t\t\t\t\t<img width=\"600\" height=\"449\" src=\"https:\/\/www.hsu.edu.hk\/wp-content\/uploads\/2021\/05\/Photo-2-1-1140x853.jpg\" class=\"attachment-large size-large\" alt=\"Wireless Localisation in Time-Varying Indoor Environment\" loading=\"lazy\" srcset=\"https:\/\/www.hsu.edu.hk\/wp-content\/uploads\/2021\/05\/Photo-2-1-1140x853.jpg 1140w, https:\/\/www.hsu.edu.hk\/wp-content\/uploads\/2021\/05\/Photo-2-1-768x575.jpg 768w, https:\/\/www.hsu.edu.hk\/wp-content\/uploads\/2021\/05\/Photo-2-1-360x270.jpg 360w, https:\/\/www.hsu.edu.hk\/wp-content\/uploads\/2021\/05\/Photo-2-1.jpg 1200w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/>\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"29 April 2021 The Deep Learning and Cognitive Computing Centre (DLC3) conducted a research seminar on 29 April 2021.
