RF Rendez-Blue: reducing power and inquiry costs in Bluetooth-enabled mobile systems
نویسندگان
چکیده
In resource-limited mobile computing devices, Bluetooth wireless technology imposes a weighty burden due to inef£cient power utilization and a sluggish device discovery process. Buttressing Bluetooth with Radio Frequency Identi£cation (RFID) technology by performing an operation we call “Rendez-Blue” alleviates these limitations. In the Rendez-Blue process, an RFID signal is used as a cue to “wake-up” a sleeping Bluetooth radio. This ensures that the Bluetooth radio is active only when needed, signi£cantly reducing power consumption. In addition, RFID is used to communicate Bluetooth device information, allowing the user to bypass the traditional 10.24-second discovery process.
