Abstract

A computer system with a software framework for supporting Wi-Fi communications that is used for WiMAX communications in a user friendly way. A Wi-Fi emulation component presents a driver interface to the framework that allows Wi-Fi user interfaces and control functions to operate with a WiMAX network card. Functions of the WiMAX card not supported through the framework may be translated within the emulation component to command objects that are passed by the framework to extensibility components. The extensibility components may be supplied in association with the network interface card. The emulation component also presents an interface to a driver for a WiMAX network interface card in a form that may interface directly with the framework, if the framework is modified to support WiMAX communications.

Claims

1. A computer storage media having a plurality of computer-executable components that, when executed on a computer, comprise:

a framework for interfacing to a driver for a wireless network card operating according to a first wireless technology;

a driver for controlling a wireless network card operating according to a second wireless technology; and

an interface between the framework and the driver for controlling a wireless network card operating according to a second wireless technology, the interface for converting status and command information between a format used by the framework for the first wireless technology and a format used by the wireless network card operating according to the second wireless technology.

2. The computer storage media of claim 1, wherein the first wireless technology comprises Wi-Fi and the second wireless technology comprises WiMAX.

3. The computer storage media of claim 2, in combination with a computer, the computer comprising a wireless network card operating according to the second wireless technology.

4. The computer storage media in the combination of claim 3, wherein the computer further comprises a wireless network card operating according to the first wireless technology.

5. The computer storage media of claim 2, wherein the framework is further adapted for interfacing to an extensibility component supplied separately from the framework the extensibility component for providing a user interface allowing a user to view and connect to or disconnect from a WiMAX network or configure settings for a WiMAX network.

6. The computer storage media of claim 1, wherein the interface presents a first standardized interface to the framework and a second standardized interface to the driver, the first standardized interface and the second standardized interface having the same format.

7. The computer storage media of claim 1, wherein:

the framework comprises a user interface component presenting a user interface having a field for status information relating to a network connection according to the first wireless technology, the user interface component adapted to issue a command requesting the status information; and

the interface is adapted to, in response to the command, obtain analogous status information from the driver and provide it to the user interface component, the analogous status information representing a condition of a network connection according to the second wireless technology.

8. The computer storage media of claim 7, further comprising a data structure mapping status and command information relating to the first wireless technology processed by the framework to status and command information relating to the second wireless technology processed by the driver.

9. The computer storage media of claim 8, wherein the status and command information comprises OIDs.

10. A kit comprising:

a wireless network interface card adapted for communication according to the WiMAX protocol;

computer storage media encoded with computer executable components comprising;

a driver adapted to interface to the network interface card, the driver having an NDIS interface;

an extensibility component adapted to perform at least one function associated with wireless communication using the WiMAX protocol that is not performed by a standard Wi-Fi network interface; and

an emulator component, adapted to translate between command objects processed by a Wi-Fi network interface and command objects processed by the driver and to format command objects from the driver for execution by the extensibility component.

11. The kit of claim 10, wherein the at least one function is a function not supported by a framework for Wi-Fi communication.

12. The kit of claim 10, in combination with a computer comprising a computer storage media having computer executable instructions that, when executed by the computer, comprise a framework for supporting Wi-Fi communication.

13. The kit in the combination of claim 12, wherein the computer executable instructions, when executed by the computer, further comprise an interface between the framework and the driver.

14. A method of operating a computer having a framework for supporting communication according to a first wireless technology according to a second wireless technology, the method comprising:

receiving a first command object in a format for execution by a network interface operating according to a first wireless technology;

mapping the first command object to a second command object; and

applying the second command object to a wireless network interface operating according a second wireless technology.

15. The method of claim 14, wherein:

the first command comprises setting an operating parameter of the first wireless technology that is not supported in the second wireless technology; and

the mapping comprises generating the second command object with an operating parameter supported by the second wireless technology in place of the operating parameter of the first wireless technology that is not supported.

16. The method of claim 14, further comprising:

generating, in a user interface component, the first command object;

receiving, in response to applying the second command object, a result; and

displaying, by the user interface component, the result.

17. The method of claim 16, wherein:

the first command object comprises a request for a network SSID; and

the mapping comprises mapping the first command object to a second command object that requests a friendly network name.

18. The method of claim 14, further comprising:

receiving a third command object in a format for execution by the network interface operating according to the first wireless technology, the third command object representing a function that is not supported in the second wireless technology; and

returning a failure in response to the first command.

19. The method of claim 18, wherein:

the first command object comprises a request for network statistics

the first wireless technology is Wi-Fi and the second wireless technology is WiMAX; and

the method further comprises displaying network statistics received in response to the second command object with a framework adapted for display of Wi-Fi network statistics.

20. The method of claim 19, wherein:

receiving the first command object comprises receiving the first command object through a first driver interface of a predefined format; and

applying the second command object comprises applying the second command object through a second driver interface of the predefined format.
