Abstract

Bluetooth Low Energy is one of the most popular technologies used by small electronic devices for wireless communication. Because it operates in an overcrowded frequency band it is exposed to a lot of interferences. This thesis focuses on the influence of Wi-Fi interferences on the communication of BLE devices. With practical experiments, we want to show different ways of countering interferences and analyze how successful BLE communication is. We found out, that interferences have an effect on advertising channels only in close proximity. When a BLE communication is established, Wi-Fi traffic on one Wi-Fi channel has little effect on the success rate of packets, as BLE uses a frequency hopping method, which almost completely negates any effect. When there is Wi-Fi traffic on the whole BLE frequency band only two channels remain, which are always the last two data channels.
