    Abstract: A wireless communication network comprising: (1) a plurality of mobile devices each configured to receive a beacon being broadcasted within the network and determine based on information transmitted within the beacon whether the mobile device is supported within the network; and (2) one or more access devices configured to broadcast the beacon within the network. Each of the mobile devices has a transmitting mechanism for communicating with the one or more access device. However, only those mobile devices that are supported by the network respond to the receipt of the beacon. Thus, no transmission occurs from the mobile devices until the device is identified as being supported by the network. These mobile devices instantiating a communication path with the one or more access devices and request an authentication from the one or more access devices. In this manner, a handshake mechanism is established between the access devices and the mobile devices that are supported by the network.

    Abstract: The present invention is a system of at least one cordless telephone, a home base station and at least one non-home base station. A roaming cordless telephone out of range of its home base station will use a non-home base station to direct digital mode signals to its home base station. The home base station will convert the digital mode signals to analog signals and communicate them with the telephone network. Only a single direct line connection is needed for the home base station, as the digital mode signals and the analog signals communications do not interfere with each other. The user may potentially avoid long distance charges by using the non-home base station as a conduit while using the home base station as the telephone network site for long distance charge accrual. Further, the necessity for using a cellular telephone with the consequent charges is avoided.
