    • A universal wireless radiotelephone communication apparatus is operative in both a first radiotelephone communication system including a first base station having a wide area of coverage, transmitting radiotelephone signals at a first band of frequencies and in a second radiotelephone communication system including a second base station having a localized area of coverage, transmitting radiotelephone signals at a second band of frequencies higher than said first band of frequencies. The second band of frequencies is optimally selected with an offset of less than twice a frequency contained within said first band. The wireless radiotelephone communication apparatus has a common baseband circuitry for operating with both the first base station covering the wide area and with the second base station covering the local area, the common baseband circuitry processing received radiotelephone signals from both base stations and processes signals generated by a user of the handset for transmission to either of these base stations.

    • A wireless device (e.g., a wireless smart phone) uses Global Positioning System (GPS) data, or other position-indicating data, to accurately determine its location in relation to multi-layered wireless networks that the device may see concurrently. If location information is available, the device employs a user-defined priority table to select the order of user-contracted networks available at that location in which the device will register. If location information is unavailable, the device employs a technology priority table to select Common Air Interface (CAI) options for the invention device radio parameters (e.g., GSM, cdma2000, IS-136, IEEE 802.11x, etc.) to search for an available network to access. Information is gathered and stored in databases within the invention device allowing it to be registered in multiple wireless networks. The inventive device provides unique access codes to each wireless network with which a user has contracted, without the intervention of any “anchor” (home) network. The invention facilitates equivalent “home”, or personalized, service in any network by using these features for automatic technology adaptation. This allows the invention device to receive service as if it is in a “home” network no matter what network it is traveling through. The invention provides a ubiquitous experience allowing the user to traverse multiple wireless networks with seamless access to multiple systems and services provided by those networks. It also provides a platform to facilitate the customization of wireless services for business customers.

    • A base station (10) for mobile radio telecommunications systems comprises a radio frame set (11), an amplifier frame (12) and an antenna interface frame (13) connected to transmit and receive antennas (22 and 23). The radio frame set (11) comprises a radio channel frame (14) including a radio control complex (31), a plurality of radio channel units (54) and a plurality of digital interface circuits (57) for interconnecting the base station to a remote mobile telephone switching office. A time division multiplexed bus (53), connected to the radio control complex (31), the radio channel units (54) and the interface circuits (57), is used for selectively connecting, under the control of the radio control complex (31), any radio channel unit (54) to any digital interface circuit (57). Such a radio channel arrangement is capable of handling analog, as well as, digital radio channel units while exhibiting greater capacity, easier maintenance and upgrade, and substantially increased flexibility (FIG. 3).
