Public Access WiFi Service (PAWS) is one such initiative that takes advantage of the available unused capacity in home broadband connections and allows Less-than-Best Effort (LBE) access to these resources, as exemplified by Lowest Cost Denominator Networking (LCDNet). \PAWS\ has been recently deployed in a deprived community in Nottingham, and, as any crowd-shared network, it faces limited coverage, since there is a single point of Internet access per guest whose availability depends on user sharing policies. To mitigate this problem and extend the coverage, we use a crowd-shared wireless mesh network (WMN), at which the home routers are interconnected as a mesh. Such a \WMN\ provides multiple points of Internet access and can enable resource pooling across all available paths to the Internet backhaul. In order to coordinate traffic redirections through the WMN, we implement and deploy a software-defined \WMN\ (SDWMN) control plane in one of the \CONFINE\ community networks. We further investigate the potential benefits of a crowd-shared \WMN\ for public Internet access by performing a comparative study between a \WMN\ and PAWS. Our experimental results show that a crowd-shared \WMN\ can provide much higher utilization of the shared bandwidth and can accommodate a substantially larger volume of guest traffic.
