Performance comparison between UWB and NB Propagation models for an indoor localization



เครือข่ายนักวิจัย+ผลงานวิจัย (full screen)


Nowadays, an indoor localization has been widely employed in some applications such as finding itself in a department store. Nevertheless, general indoor localization has the moderate effectiveness which some applications require high accuracy to use in Emergency situations. Thus, the indoor localization has been improved in many ways. Normally, most methods are acceptable to use in finding a location within the building such as WLAN with the fingerprinting technique. Therefore, the fingerprinting technique was used in this paper. Then, narrowband (NB) and ultra wideband (UWB) signals were compared in order to show about the efficiency in the indoor localization. The channel model was used from VNA at the frequency range 3 GHz to 11 GHz. As the result, the best result of UWB Localization modeling has yield as 90.84% at 1 meter accuracy value in 3 rooms whereas the best result of WLAN Localization modeling has yield as 36.64% at 3 meters accuracy value in 3 rooms. Then, UWB signal is more suitable than NB signal. © 2014 IEEE.
