Coexistence issues for a 2.4 GHz wireless audio streaming in presence of bluetooth paging and WLAN

[摘要] Nowadays, customers expect to integrate their mobile electronic devices(smartphones and laptops) in a vehicle to form a wireless network. Typically,IEEE 802.11 is used to provide a high-speed wireless local area network(WLAN) and Bluetooth is used for cable replacement applications in a wirelesspersonal area network (PAN). In addition, Daimler uses KLEER as thirdwireless technology in the unlicensed (UL) 2.4 GHz-ISM-band to transmitfull CD-quality digital audio. As Bluetooth, IEEE 802.11 and KLEER areoperating in the same frequency band, it has to be ensured that all threetechnologies can be used simultaneously without interference. In this paper,we focus on the impact of Bluetooth and IEEE 802.11 as interferer inpresence of a KLEER audio transmission.
