Place Sticker : Energy Harvesting Approach for Low Cost Wi-Fi AP Positioning Infrastructure

In order to realize a feasible and low-cost indoor positioning, we implemented prototypes of energy-harvesting Wi-Fi AP’s and conducted evaluation experiments at the underground shopping mall in Osaka. Solar panel driven access points only transmit a unique beacon but do not perform any other functionality in order to conserve energy. The unique beacon can be used for Wi-Fi positioning from ordinary Wi-Fi devices. We controlled beacon transmitting power to adapt positioning precision and obtained average 0.4m at most and 3.2m at 10m-pitch layout for both stationary status and walking status in the underground mall.
