https://techcrunch.com/2018/05/21/comcasts-mesh-wi-fi-system-xfi-pods-launches-nationwide/ > Comcast today is officially launching its own Wi-Fi extender devices called xFi Pods that help to address problems with weak Wi-Fi signals in parts of a customer’s home due to things like the use of building materials that disrupt signals, or even just the home’s design. The launch follows Comcast’s announcement last year that it was investing in the mesh router maker Plume, which offers plug-in “pods” that help extend Wi-Fi signals. > The company said that it would launch its own xFi pods that pair with Comcast’s gateways to its own customers as a result of that deal.
