We propose SCALED, an architecture that extends the energyharvesting range of ultra-low-power platforms. We explore two design questions: (1) The design of the energy harvester, including which ambient frequency bands to combine as well as overall modalities to combine energy rather than focus on one band; (2) The design of radio infrastructure to fill-in the coverage gaps of ambient energy, with minimal interference to communication sources. We implement and study SCALED through a multi-pronged evaluation including building-scale proof-of-concept deployments.
