SNUPI (Sensor Nodes Utilizing Powerline Infrastructure) nodes are ultra-low-power, general-purpose 27 MHz wireless sensor nodes that transmit their data by coupling over the powerline to a single receiver attached to the powerline in the home. We've demonstrated the ability of our general purpose wireless sensor nodes to provide whole-home coverage while consuming less than 1 mW of power when transmitting (one order of magnitude lower than existing nodes), and our custom CMOS transmitter consumes only 65 µW (two orders of magnitude lower than existing nodes). Compared to those found in traditional whole-home wireless systems, this is the lowest power transmitter to date.
