Performance impairments of Bluetooth systems in EMI environment specified by WLAN transmissions

Bluetooth and wireless LAN devices use the same 2.4 GHz band and they can interfere each other. In this paper, a systematic analysis is presented to calculate the frame error rate in the Bluetooth systems impaired by electromagnetic interference (EMI) from wireless LAN transmissions. Considerations of GFSK modulation adopted are duly taken into account. The effects of EM radiation from the wireless LAN system in the transmission mode on the relevant performance impairment are determined. Simulation studies on Bluetooth communications consistent with the available details pertinent to EMI from the wireless LAN system are presented, and, relevant conclusions on the interference involved are elucidated.
