Submission + - Readerless RFID: Berkeley's Mesh Network

donzo writes: "eWEEK has an article about advances in RFID: "UC/Berkeley researchers have created tiny wireless 'motes' (aka network sensors) that use radio signals to communicate where they are located in physical space. The end goal: an RFID network that could revolutionize the industry with its ability to locate tagged items without the aid of readers... 'What we showed in the university was that you could network together a lot of sensors,' said Kristofer Pister, a professor of Electrical Engineering and Computer Science at UC/Berkeley who made a name for himself with his 1997 development of technology called Smart Dust — a self-organizing network of tiny wireless 'motes.'... Intended to be about the size of a grain of sand or a piece of dust — the motes from Dust Networks are currently about the size of a quarter — the motes contain sensors, computing circuits, bi-directional wireless technology, and an antenna and very low-battery power supply that are external to the chip. The motes can detect light, temperature or vibrations."

To the systems programmer, users and applications serve only to provide a test load.
