Bluetooth and Wi-Fi Interference Simulations and Solutions

Abstract: Bluetooth and IEEE 802.11b or Wi-Fi, both use the same unlicensed Industrial, Scientific and Medical (ISM) band in the frequency range of 2.4 GHz. As the demand and utility of Bluetooth and Wi-Fi devices has increased, the number of co-located devices has also increased in number, so there can be interference issues related to these devices. This review paper investigates interference of Wi-Fi signal in Bluetooth data or voice link with the help of simulations from MATLAB Simulink Bluetooth full duplex communication model. This review paper also discusses the techniques to improve the performance of Bluetooth and Wi-Fi co-located systems.
