Abstract-With the spread of IT technologies, we offer a novel near field user detection method by convenient and correct way to take advantage of the Wi-Fi 802.11x technology on smart mobile devices. In this research managers initiate AP mode Wi-Fi service or BLE peripheral advertisement for user detection. The key algorithm in this research is as follows; An advertisement signal is broadcasted only to a person who is closed to the Wi-Fi AP or BLE beacon. If a member has detected advertisement signal, a smart application of the member(or student) will connect and report to the server that the member are near the manager node. If the member does not get the advertisement signal, the smart application of member will report to the server that the users/students are not near the manager node. By this way instructors/managers can conveniently check whether members are near the instructors/manager nodes.
