Getting sensors out of the lab and deployed in our cities holds the promise of enabling a deeper understanding of our urban environments. However, the realities of deploying these systems are that an enormous amount of engineering effort must be completed before even simple exploratory deployments can occur. Signpost is one potential solution to this problem, reducing the barrier to entry by providing resources to plug-and-play sensing modules. We'll discuss the design of Signpost and how it addresses the needs of city-scale sensing. One particular need Signpost addresses is that of wide-area wireless communication. We'll dig deeper into this issue and explore several new low-power, wide-area networks that have the potential for enabling city-scale deployments. These networks are not without challenges, however, and we'll discuss how well existing networks can serve real-world application needs.
