An investigation of the coexistence of 802.11g WLAN and high data rate Bluetooth enabled consumer electronic devices in indoor home and office environments

The anticipated proliferation of various wireless local area network (WLAN) enabled devices in the near future is likely to result in increased mutual interference in the 2.45 GHz industrial, scientific and medical (ISM) band. The paper investigates the impact of standard Bluetooth and high data rate (HDR) Bluetooth interference on IEEE 802.11g enabled consumer electronic devices and vice versa. Technical design issues for HDR Bluetooth and 802.11g systems implemented in software are presented. Packet error rate (PER) versus signal-to-noise ratio (SNR) plots are presented. The improvement in performance attained in 802.11g systems by using erasures in the corrupted subcarriers is briefly discussed.
