A Study of the Accuracy of the Software Site Survey to Find the Appropriate Location to Install the Access Point for Indoor Positioning

Currently, there are many researches trying to find the position of people inside the building or indoor positioning to apply in many different applications in the future. This research is an early stage, the idea is to find the location of people inside the building through the Wi-Fi signal from the access point. This paper will present the location to install the appropriate access point device inside the building to further develop the indoor positioning system. A comparative analysis of the access point’s design and operation was performed using a Software Heat Map Planner called Ruckus Wireless ZonePlanner, a software license from Ruckus, designed specifically for Wi-Fi systems and using Software Site Surveys to collect data to verify the accuracy of the information. Three software site surveys, Wi-Fi Analyzer, Net Spot, and inSSIDer Home, were used to find average data collection. Then compare with the Software Heat Map Planner to see how much signal quality deviation and signal quality is measured when the signal is broadcast through the walls of the building’s infrastructure: concrete, brick walls, glass walls with metal frames. Summarize the results of each signal quality analysis, the signal quality is between −29 and −68 but based on actual measurements using 3 different software, the signal quality is between −29 and −74, the least error is 9 and the maximum is −28.
