Several Wi-Fi access points (WFAP) are setup in indoor environment and provide high-quality Internet services. However, the Wi-Fi signal is vulnerable for the impact of the surrounding environment as well as the WFAP are fixed at specific location. The WFAP cannot provide the same signal strength to every covered region. Further, the signal strength for some regions are poor. This study uses the BLE beacons, smart phone, and web service technology to implement a movable device to carry a WFAP. Then, some software design patterns, such as factory pattern, strategy pattern, and observer pattern, are utilized for building an application for smart phone usage. Utilizing the indoor positioning, the mutual positions of the smart phones and WFAP can be collected. On basis of the location information of the smart phones and movable devices on the WFAP, our system can instruct the movable device to carry the WFAP to the nearest location from the smart phone. Our research results show that the average error between the calculated of position and the actual position of the smartphone is 0.81 meters. And the average error of the smartphone and the moveable device after moving by the smartphone application instruction is 1.17 meters. Therefore, we can move the WFAP closer to the smart phone and provide better accessing environment for the user according to the position of the smart phone in the indoor environment.
