SpecScape comprises cloud-managed computing and data repositories that are fed by a large number of mobile (vehicle-mountable) sensor kits (which we call SpecTiles) — SpecTiles together provides a high level overview of SpecScape architecture. Users log into the cloud-hosted portals to access with an end-to-end software ecosystem to handle such crowd-sourced data creates SpecScape. and pose spectrum queries across many SpecTile sensors. Each kit will be designed to be easily mounted in a vehicle (with appropriate power and battery hookup to its ignition). Each SpecTile kit can be deployed by researchers, volunteers, and citizen scientists in their own personal or fleet vehicles. Each SpecTile kit, is going to be cheap, cover the entire sub-8 GHz spectrum, including all the WiFi- 6 bands, is designed by leveraging the most popular analog devices chipset AD9363, used in all SDRs, Further, the sensor comes with an integrated general-purpose compute node, based on an ARM proces- sor, to allow for flexible computing right on the sensor board. To allow experimenters to deploy compute capabilities in this general-purpose compute node, we use an open-sourced, edge compute software in- frastructure, called ParaDrop . In SpecScape, an experimenter can therefore create spectrum queries whose compute functions can be partitioned across cloud-hosted resources as well as in the mobile sen- sors themselves, all orchestrated by our software ecosystem.
