TL;DR: It is shown that both the horizontal positioning accuracy and the floor detection probability can be improved with proper interpolation and extrapolation methods, and it is also illustrated that the best positioning performance is not necessarily achieved with the best average interpolationand extrapolation accuracy.

TL;DR: The new design of WLAN 802.11ax can significantly reduce the latency of the system, and offer increased sleeping opportunities on both base station and user equipment sides leading to enhanced power savings, and is able to improve the channel utilization when compared with LTE-A.

TL;DR: The purpose of this paper is to address the path-loss channel models and shadowing effects for WLAN and RFID signals based on extensive measurement campaigns in an office environment, and to envision a near future where multiple RFID and WLAN signals will co-exist on multiple frequency bands.

TL;DR: In this article, the authors presented a novel hybrid configuration for indoor positioning, utilizing the passive radio frequency identification (RFID) and wireless local area network (WLAN), based on a mobile device with a WLAN receiver, a textile RFID tag and one or several RFID readers communicating with the mobile.

TL;DR: An extensive analysis of the performance evaluation and enhancement study of the IEEE 802.11ah network when multi-access points (multi-APs) with relatively high number of associated stations (STAs) are considered, which confirms the importance of the Restricted Access Window mechanism to improve substantially the overall system performance.
