This document summarizes a summit on in-building wireless held on October 2, 2013 at the Kellogg Conference Hotel. It provides statistics on the growth of the distributed antenna system (DAS) and small cell industry, noting these technologies are important for improving indoor wireless coverage and capacity. It also discusses challenges like obtaining power, real estate and backhaul for these systems. The document concludes that macro cells, small cells and DAS need to work together to provide better overall wireless service, and small cell deployments are expected to grow significantly in the coming years.
