Abstract

Embodiments of the invention allow the automatic acquisition and tracking of a communications node and the initiation of a communications link with a network through the acquired communications node. Automatic acquisition and tracking reduce or eliminate the need for prior location information in connection with communications nodes that may be used as intermediaries for connection to the network. Further, images taken during acquisition and tracking maybe analyzed to extract authentication information regarding an intermediary communications node, or timing information indicating when the intermediary communications node maybe available for a connection.
