IEEE 802.11 and Bluetooth, these two operating in the unlicensed 2.4 GHz frequency band are becoming more and more popular in the mobile computing world. The number of devices equipped with IEEE 802.11 and Bluetooth is growing drastically. Result is the number of co-located devices, say within 10meters, grown to a limit, so that it may cause interference issues in the 2.4 GHz radio frequency spectrum. Bluetooth supports both voice (SCO) and data (ACL) packets. This paper investigate these interference issues and use a new Bluetooth voice packet named Synchronous Connection-Oriented with Repeated Transmission (SCORT) to study the improvement in performance.
