The local wireless networking techniques are becoming more and more popular in mobile terminals nowadays. Even so that Wireless LAN (e.g. IEEE 802.11b) and Bluetooth solutions operating at the 2.4 GHz ISM band can be found in the same device. This enables new kind of usage possibilities and applications from which the most challenging ones, from interoperability point of view, are those that require simultaneous real-time operation over these links. One good example of this kind of service is a Voice over IP (VoIP) call over the WLAN to the terminal with a Bluetooth headset. In this paper problems regarding different receiver architectures are presented and solutions for optimized Bluetooth usage are considered.
