Evaluation of dynamic Localization System Based on UWB and Wi-Fi for Indoor Environments

Due to limitations and complexity in indoor communications, many wireless technologies deployed to correspond with those challenges. The Ultra-Wideband (UWB) wireless communication for indoor environments is one of the widespread bands developed for convey high data rate. The other widespread band is 2.4GHz based on Wi-Fi technology. Each of the mentioned bands could be convenient for specific areas and not for others based on long or short-range communications. In this paper, both bands are applied for indoor environments to find the target’s locations. A new technique based on Multi-Scale Bands with Dynamic approach (MSBD) is applied to implement an optimum system. The three dimensional (3D) case study building designed based on Wireless Insite Package with real building geometric measurements. It is worth to mention that both bands are applied based on dynamic parameters to assign specific parameters for specific environments. The average error in the whole building based on static parameters using UWB is (1.023m) while (0.452m) based on individual 2.4GHZ. The obtained results confirm that the proposed MSBD technique is significantly outperformed individual band with static parameters. The enhancement is noted from error range which improved from (1.023m) to (0.08m) for UWB and (0.452m) to (0.15m) for 2.4GHz. For optimum system, the UWB was deployed for a distance under (10m) and Wi-Fi for other distance. By deploying both technologies and using the dynamic system, the performance of the proposed system worked with accurate measurements in short and long-distance in addition to both LOS and NLOS scenarios identify relevant articles in literature searches, great care should be taken in constructing both.
