    摘要: With the advent of many high-tech intelligence appliances. People's lives more and more convenient .And the prosperous development of smart phones new smart phone applications constantly emerge in the daily life. Whenever there is a new application of smart phone introduced in the market it will always generate pro and con heated discussions. If the appliance can combine with the phone application, but can increase the intelligence function appliances. Following the development of BLE (Bluetooth Low Energy) Bluetooth related applications also become a hot topic at the present time and the study of applying Bluetooth in the indoor positioning has also appeared in many research fields. wearable device 3C overnight become the new darling of the industry.
    In this paper, we make field measurement of the path loss in the Bluetooth wireless transmission path and also in the measurement including obstacles and human blockings to investigate their effect on the wireless signal transmission so as to establish an accurate positioning methodology in order to facilitate the application on the actual product.
    In this paper, we use MATLAB program to create a GUI interface. The user can choose the test scenario that he would like to review, and then the program will automatically plot the path loss curves for the selected test scenario and will mark the test data points; and consequently from the plotted curves the user can make the decision to determine the distance between the transmitter and receiver being a near-range, mid-range or a long-range and then this information will be used as reference when using Bluetooth as a positioning technique. And by using the Android platform to develop a wireless signal strength to determine distance apps.
