Wi-Fi networks have gained tremendous success in delevering wireless broad band access. However, traditional Wi-Fi Hot Spots rely on wired networks as backhauls. Wireless Mesh Networking (WMN) technology , which our solution is based on, enables us to build a network that is self-organizing and self-healing.

As illustrated in the following figure, the network architecture consists of two parts, the mesh backbone and local footprints. All the mesh modes are equipped with two wireless interfaces. One is an IEEE 802.11a/g compliant radio, which is the backbone traffic carrier. Another is an IEEE 802.11b radio, which provides access to wireless clients in the local footprint. It supports standard configured wireless clients, which usually have off-the-shelf IEEE 802.11 hardware. Wireless clients can have access to the Internet or intranet through the wireless mesh backbone. Arriving users can immediately join the network when they come into range and turn on their devices.
