摘要: We design and use a software tool capable of automatically checking the attendance an enrolled student by using smartphone. The needs to install application on his/her challenging issue is that we need find out if inside or outside classroom. For this purpose, smartphone will measure current signal strength Wi-Fi Bluetooth devices near measurement results are reported server running check student. can analyze strengths determine whether A comprehensive WiFi signals shows scanning consumes more energy than BLE scanning. Also, received beacon change dynamically due interference fading. In other words, not able location in classroom signal. If place device, adjust transmission power level. This helps improve accuracy By leveraging perform highly advanced measurement.
