Does anyone have any knowledge on the possibility of passive bluetooth? The idea is much like what is used in some applications of RFID. A bluetooth enabled tag (tank circuit like) which would acquire power from the transmitted source and reflect back. The data transferred would not need to be extensive, just a few bytes.
The reason I ask; RFID in even simple applications is still hindered greatly by distance and RF disturbances (metal, etc.). It seems to me that bluetooth would be more stable due to it's lower frequency, but obviously more costly unless the tags could be passive. I suspect that even a 10 foot clear transmission would have excellent applications. Especially in security, location identification, etc.
Has anyone had any experience in this area? Perhaps someone could point me in a good direction. Thank you in advance.
Passive Bluetooth?
