"The Berkeley guys are working on the dust mote, 1 mm2 target size
including the radio chip. The biggest limitation now is the battery power
and the radio range. Even if they can get the size down to "dust", the
antenna HAS TO BE 1/4 of the radio wave length. For the 433 MHz version
this is around 8-10 inches! So these dust motes will have "tails".
Eventually, these could painted on the wall, or dumped from the air for
millitary applications. Lot's of unsolved problems. For sensor networks,
how do you obtain large amount of data through a few base stations? Smart
aggregation and routing protocols need to be employed, and the network
must process the data by itself."
