Investigating the Access Point height for an indoor IOT services

Abstract

The prospects of location estimation and localization approaches in Wireless Local Area Network (WLAN) by using Received Signal Strength (RSS) have gained significant resonance recently. Selecting the appropriate highest for Access Point (AP) and Transmitter devices can achieve higher accuracy for different localization approaches and IoT (Internet of Things) based services. In addition, reducing the shadow fading effects and increasing the coverage area. In this paper, the effect of different AP height on the variation of signal strength was investigated with a height ranging between (1-2.5) m. The obtained RSS measurement indicates that AP height at 2.5 m can achieve best RSS measurement with respect to receiver height of (1.10) m, especially for NLoS received points. Furthermore, RSS measurement system has been designed and utilized for this investigation. The measurement system is connected with an open based cloud platform for aggregation, visualization and analysing the measurement data. The proposed system can achieve high-speed RSS measurements, low-cost implementation and provide more facilities in collecting and monitoring a huge amount of data.
