Abstract

The invention includes an apparatus and method for allowing a client to access a wireless system. The system includes at least a first wireless access node. The method includes the first wireless access node detecting a client seeking access to the system. The first wireless access node being able to wirelessly connect to a back bone network. Client information is obtained. The first wireless node provides the client a communication path to and from a destination. The communication path is able to include wired and wireless communication links. Routing of information through the communication path between the client and the destination is aided based upon detection of the client. The wireless connection between the first access node and the back bone network can include at least one wireless hop between the first access node and a third access node.
