Abstract

A reconfigurable wireless modem adapter is provided. The reconfigurable wireless modem adapter includes a control board and a radio frequency switch. The control board has at least two interfaces for a respective at least two modems and is configured to communicatively couple to at least one onboard system in a vehicle. The control board activates a selected modem interfaced to one of the at least two interfaces. The radio frequency switch is communicatively coupled to the control board via the selected one of the at least one modem. The radio frequency switch communicatively couples an antenna to the selected modem. When the control board is communicatively coupled to the at least one onboard system and activates the selected modem, and when the radio frequency switch is communicatively coupled to the antenna, the antenna is communicatively coupled to the at least one onboard system via the selected modem.

so that when the control board is communicatively coupled to the at least one onboard system, when the control board activates the selected one of the at least one modem, and when the radio frequency switch is communicatively coupled to the at least one antenna, the at least one antenna is communicatively coupled to the at least one onboard system via the selected one of the at least one modem.

2. The reconfigurable wireless modem adapter of claim 1, wherein the control board includes:

a data multiplexer; and

control logic to configure the data multiplexer to activate the selected modem, wherein the data multiplexer routes user data from the onboard system to and from the selected modem.

3. The reconfigurable wireless modem adapter of claim 2, wherein the control board further includes a processor to perform an analysis based on information indicative of available service providers, and to output information indicative of the selected one of the at least one modem based on the analysis, wherein the control logic receives the information indicative of the selected one of the at least one modem and configures the data multiplexer based on the received information to activate the selected one of the at least one modem.

4. The reconfigurable wireless modem adapter of claim 3, wherein the information indicative of available service providers includes information indicative of the service providers currently available via the antenna, information indicative of data bandwidth available from the currently available service providers, information indicative of a cost of using the currently available service providers, and information indicative of a quality of service provided by the currently available service providers.

5. The reconfigurable wireless modem adapter of claim 3, wherein the analysis is a cost/performance analysis.

6. The reconfigurable wireless modem adapter of claim 1, wherein the control board is connected to a data-loader interface, and wherein a data loader attached to the data-loader interface is communicatively coupled to the control board.

7. The reconfigurable wireless modem adapter of claim 1, wherein the vehicle is an aircraft, wherein the reconfigurable wireless modem adapter is an aeronautical reconfigurable wireless modem adapter, and wherein the onboard system is one or more of a communications management unit and a cabin server.

8. The reconfigurable wireless modem adapter of claim 1, wherein the at least two interfaces are selected from a combination of two or more of the following:

at least one personal computer memory card international association (PCMCIA) interface;

at least one universal serial bus (USB) interface;

at least one peripheral component interconnect (PCI) interface; and

at least one subscriber identity module (SIM) interface in a digital switch communicatively coupled to a subscriber-identity-module-compatible modem, and wherein the at least two modems are selected from a combination of two or more of the following;

at least one PCMCIA modem, at least one USB modem, at least one PCI modem, and at least one subscriber-identity-module-compatible modem that is operable to interface with a SIM card.

9. The reconfigurable wireless modem adapter of claim 1, further comprising:

a digital switch, wherein the control board sends a control signal to the digital switch to connect one of at least two subscriber identity module cards to the control board via one of the at least one modem.

10. A method to use data services to move data onto and off of a vehicle, the method comprising:

communicatively coupling an interface of a control board to at least one onboard system on the vehicle;

communicatively coupling an antenna on the vehicle to a radio frequency switch;

selecting one of at least one data service provider available to the antenna at the control board;

configuring a data multiplexer on the control board to activate a selected one of at least one modem based on the selecting of the available data service provider, wherein the control board is communicatively coupled to the radio frequency switch via the at least one modem; and

initiating a network acquisitions process based on processing internal to the selected modem.

11. The method of claim 10, wherein communicatively coupling the control board to the radio frequency switch via the at least one modem comprises:

attaching the at least one modem to an interface connected to the control board;

communicatively coupling the attached at least one modem to the radio frequency switch, the method further comprising;
