The table below describes the family in more detail. RF Mote RF 916. Since then, various projects have been undertaken to test communication protocols for distributed sensor networks with the RF motes. 10's of km range. The Laser Mote has been used to demonstrate the long range communication capabilities in small packages.
Range is function of the intensity of the laser.
The device is being used as a test platform to demonstrate the communication algorithms that will ultimately be implemented on Smart Dust. The Mini Mote is a miniaturized version of the RF Mote. It's smaller size and simpler circuit design makes it both cheaper and easier to handle. Algorithms are underway to investigate how two such devices can locate and communicate to one another without initially knowing the location of the other device. The primary advantage of the weC mote is that it can be reprogrammed wirelessly.
