Abstract
Official abstract text for this publication.
Methods and systems are disclosed for reducing signal interference between Bluetooth (BT) and WLAN (e.g. WiFi) communications in an information handling system. The WLAN receiver has configurable front-end filter circuitry. Based upon information concerning the BT frequency region for current BT communications, the WLAN receiver can adjust or set its configurable front-end filter circuitry to filter out the BT communications. As the BT communications hop from frequency to frequency, the WLAN receiver can continue to adjust its configurable front-end filter circuitry accordingly. Example implementations for the configurable front-end filter circuitry include bandpass filters and selectable low pass and high pass filters. These filters are selected and/or tuned such that BT frequency regions are filtered from the WLAN input signal before further WLAN signal processing is conducted, thereby improving the performance of simultaneous BT and WLAN communications.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of reducing signal interference between simultaneous Bluetooth and WLAN communications in an information handling system, comprising: providing an information handling system with a Bluetooth transceiver and a WLAN transceiver, the WLAN transceiver having a configurable front-end filter system including a tunable bandpass filter; identifying a channel for WLAN communications; selecting a channel for Bluetooth communications, the Bluetooth commun…
