That's the #1 use I have in mind. People who are building devices that need low-power and short-range communication may also find this technology interesting and may find a role for ATBEN/ATUSB. Likewise, those who already have IEEE 802.15.4 devices may find a role for ATBEN/ATUSB. I don't know enough about the industrial/sensor sector to venture a guess on whether ATBEN/ATUSB could be popular there. There is a fair amount of activity in this area also in the Free Software community, e.g., with the Contiki OS [1]. They also have a list of hardware they support or are at least aware of [2].

This would mainly depend on the duty cycle of their application. If all they do is send a few bytes of sensor data every few hours, there could be tens of thousands nodes in a PAN. (PAN = Personal Area Network, the equivalent to a single LAN in WiFi terminology.) - Werner _______________________________________________ Qi Hardware Discussion List Mail to list (members only): discussion@lists.en.qi-hardware.com Subscribe or Unsubscribe: http://lists.en.qi-hardware.com/mailman/listinfo/discussion
