Simultaneous Bluetooth and Wi-Fi scanning on Android

I have developed the code for continuous and simultaneous Wi-Fi (link) and Bluetooth (link) scanning. I found out that when both scannings are activated then the number of Wi-Fi ScanRe开发者_StackOverflow社区sults drops approximately by half. Can I assume that it could be the interference issue?

Their signals interfere with each other if they are in the same wave range. It looks like this is the case. See this post for the wifi/bluetooth GHz ranges; it may also provide you with additional information you are looking for: Bluetooth protocol over wifi?
