Conclusion Since IEEE wireless protocol was launched about a decade ago, Wi fi technical criteria have been beautifully shaped and trusted due to the high-speed, wireless connection and large coverage of the Wi fi technology. Currently the demand pertaining to real-time position information of mobile users is unmatched. For outdoor environments, applying GPS can achieve high accuracy positioning results.
Nevertheless , in interior environments, due to the attenuation or obstruction of GPS alerts, GPS technology cannot be utilized effectively. Therefore , Wi-Fi centered positioning technology has been searched and developed for inside environments. From this thesis, the large market potential and fast development of mobile phones technologies were briefly assessed. It is figured the integration of the smartphones and Wi-Fi for indoor setting is a popular direction in research and industry commercialization. The main difficulties for indoor environment will be discussed with the conclusion that the fingerprint approach based on REALLY SIMPLY SYNDICATION is the optimum solution plus the smartphones is the most suitable mobile phone device due to its wide consumption. Commonly used evaluation methods and algorithms of fingerprint technique are analyzed. We successfully implemented a Wi-Fi based indoor setting system utilizing a smartphone plus the fingerprint-based positioning method.
A number of case studies had been designed and field trials were executed using several mobile systems (i. e. smartphone, ipad tablet and laptop) and the creation and requirements of software and hardware systems had been described. The statistical reaction to the placing errors(the maximum and minimum errors had been 4. 79 m and 0. 49 m respectively) in the specific indoor environment. This is in comparison against our testing program results of 2 m, which can be, more specifically, the space resolution of the greatest matching criteria. The activities of both equally systems were affected by the caliber of the REALLY SIMPLY SYNDICATION observations accumulated from a smartphone. The existing smartphones have got limitations within the quality of Wi-Fi adapters. It is predicted that more expensive and appropriate sized Wi-Fi adapters will be available in smartphones in future. The spatial resolution of the recommended indoor positioning system could be further improved by preparing more complex inside environment, and increasing the number of APs or perhaps combining various sensors into the smartphone.
Several elements can be further explored to boost the functionality of the suggested Wi-Fi centered positioning program for future work. Three main aspects are listed as follows:
