Bluetooth technology has been widely adopted in consumer or mobile devices due to its small form factor and low product cost. However increasing demand for high-speed multimedia applications continuously stimulates Bluetooth to adopt an alternative MAC and PHY technology. In this paper, we propose a dual-mode Bluetooth application which uses both a legacy Bluetooth module for low-speed communication and an alternative UWB module for high-speed Bluetooth communication. We modified legacy Bluetooth profiles for high definition video transmission and developed UWB SoC that can be used for high speed Bluetooth communication.
