UW CSE’s SNUPI at Technology Alliance “Innovation Showcase”

SNUPI (Sensor Nodes Utilizing Powerline Infrastructure) nodes are ultra-low-power, general-purpose wireless sensor nodes that transmit their data by coupling over the powerline to a single receiver attached to the powerline in the home. SNUPI nodes provide whole-home coverage while consuming less than 1 mW of power when transmitting (one order of magnitude lower than existing nodes), and a new custom CMOS transmitter consumes only 65 µW (two orders of magnitude lower than existing nodes). SNUPI was one of five technologies features at the Technology Alliance “Innovation Showcase.”
