Benefits of technology

[0008]According to the present invention, a technique including a method for using a mobile communication device is provided. In an exemplary embodiment, the present invention provides a technique for using two distinct radio interfaces to transmit and receive digital information. By way of the present technique, numerous mobile units will be distributed and used throughout a selected region or nationally or globally. The invention relates to a data transmission method in a wireless communications system comprising in each cell at least one base station communicating with mobile stations within its coverage area, in which method extra known reference information is added to a transmit signal. To enable an efficient use of bandwidth, information that is of interest to multiple users is broadcast over a dedicated channel to the receiver interface and the separate transceiver interface is used for communicating high value, low volume information in both directions with the device.

[0010]In a preferred embodiment the two wireless networks can be integrated together via hardware or software at the device and backend network layers. The two networks can be utilized to provide more efficient use of wireless bandwidth and more cost-effective access to wireless information for the device user, the carrier, a content provider, a services provider, or a party to a transaction.

[0019]Information can be sent down a one-way wireless network that provides a new frequency for the two-way network radio interface in the device to be tune to.In a preferred embodiment the two networks can be utilized to provide more reliable access to wireless information.

Problems solved by technology

The higher cost network is relative in cost to the lower cost network.
