This paper describes the deployment and evaluation of a 700MHz WiFi-based Wireless Mesh Network (WMN) testbed. To the knowledge, this is the world's first WiFi-based testbed using the recently-released 700MHz frequency band and deployed under both indoor and outdoor environments, including open space and a Louisiana swamp with dense cypress trees. Initial experimental results show that the 700MHz WMN has a significantly larger transmission range and better penetration ability compared to a traditional 2.4GHz WMN, which indicates that utilizing the 700MHz frequency band will considerably enhance the performance of WMNs, including the ability to support real-time applications.
