藍芽是短距離的無線傳輸技術，運作在2.4GHz ISM band。和無線網路(WLAN)使用相同的頻率，因此會受到WLAN的干擾。Specification of the Bluetooth System, Core Version 1.2 [2] 中新加入Adaptive Frequency Hopping (AFH)，透過選擇藍芽跳頻運作頻道的方式，避開受WLAN干擾的頻道以減少干擾的情況。但是AFH在受到干擾嚴重的地方，如有三個以上的WLAN Access Point，其效能還是會下降。
另一個方法是Interference Aware Packet Selection (IAPS)，透過能即時根據傳送封包所在的藍芽頻道，選擇適合的封包傳送機制，以減少干擾造成的影響。藉由使用IAPS可以解決AFH在干擾嚴重的情況下所產生的效能下降問題。
這篇論文將兩種方法結合，在受到干擾嚴重的地方可以有好的效能表現。
