Abstract
Abstract A method and apparatus are provided for establishing wireless communications between multiple standardized information networks and non-standardized information devices. Communicating networks may operate in accordance with the same or different standards. For each network, virtual proxy nodes are formed which represent each of the other communicating networks and each of the non-standardized information devices.
