Abstract

A system and method for providing the ability to discover the capabilities of a user'"'"'s computer to determine whether it is capable of supporting more than one wireless protocol simultaneously is provided. A computing device'"'"'s capabilities (including, for example, hardware and/or software capabilities) is checked to determine if it supports at least two specific wireless protocols and checking a computing device'"'"'s capabilities (including, for example, hardware and/or software capabilities) is checked to determine if it supports both wireless protocols simultaneously. The techniques for determining the computing device'"'"'s compatibility may include comparing lists of protocol requirements to lists of system capabilities and/or generating test signals by the system according to the protocol.

Claims

1. A method of using a Software Defined Radio (SDR)-enabled wireless device, the SDR-enabled wireless device comprising hardware and/or software for wireless communication and having system parameters indicating capabilities of the hardware and/or software, the method comprising:

a) receiving a request for performing simultaneous communication according to a first wireless protocol and a second wireless protocol, the first wireless protocol having first protocol requirements for communication and the second wireless protocol having second protocol requirements for communication;

b) determining whether the hardware and/or software of the SDR-enabled wireless device supports simultaneous communication according to the first wireless protocol and the second wireless protocol based at least in part on comparing requirements for the simultaneous communication to the system parameters that indicate the capabilities of the hardware and/or software for wireless communication; and

c) when the hardware and/or software supports simultaneous communication according to the first wireless protocol and second wireless protocol, enabling simultaneous communication according to the first and second wireless protocols.

2. The method of claim 1, wherein receiving said request for performing simultaneous communication according to the first and second wireless protocols comprises receiving a request of a first provider for performing communication of the first wireless protocol and thereafter storing information regarding whether the device is in communication via the first wireless protocol.

3. The method of claim 2, wherein receiving said request for performing simultaneous communication according to the first and second wireless protocols comprises receiving a request of a second provider for performing communication of the second wireless protocol and receiving information about the requirements for simultaneous communication according to the first and second protocols.

4. The method of claim 2, wherein receiving said request for performing simultaneous communication according to the first and second wireless protocols comprises receiving a request of a second provider for performing communication of the second wireless protocol and thereafter transmitting test signals simultaneously using the first and second protocols to determine whether simultaneous communication is supported.

5. The method of claim 1, wherein comparing the requirements for the simultaneous communication to the system parameters comprises comparing system requirements to system parameters on communication software installed on the SDR-enabled wireless device.

6. The method of claim 1, wherein comparing the requirements for the simultaneous communication to the system parameters comprises comparing system requirements to system parameters on communication hardware installed on the SDR-enabled wireless device.

7. The method of claim 1, further comprising splitting a bitstream of the first wireless protocol into first parallel bitstreams each of a first bandwidth and splitting a bitstream of the second wireless protocol into second parallel bitstreams each of a second bandwidth.

8. The method of claim 7, wherein enabling simultaneous communication of the first and second wireless protocols comprises enabling simultaneous communication by matching to a smaller bandwidth of the first and second bandwidths.

9. The method of claim 8, wherein matching to said smaller bandwidth of the first and second bandwidths comprises dividing sub-channels of one of the first and second bandwidths into a bandwidth of a larger bandwidth of the first and second bandwidths.

10. The method of claim 1, wherein, in determining whether the hardware and/or software supports the simultaneous communication, the comparing comprises comparing the system parameters to a combination of the first protocol requirements and the second protocol requirements.

11. A method of using a Software Defined Radio (SDR)-enabled wireless computing device, the SDR-enabled wireless device comprising hardware and/or software for wireless communication and having system parameters indicating capabilities of the hardware and/or software, the method comprising:

a) receiving a request for performing simultaneous communication according to a first wireless protocol and a second wireless protocol, the first wireless protocol having first protocol requirements for communication and the second wireless protocol having second protocol requirements for communication;

b) merging the first protocol requirements and the second protocol requirements to yield requirements for the simultaneous communication;

c) determining whether the hardware and/or software of the SDR-enabled wireless device supports simultaneous communication according to the first wireless protocol and the second wireless protocol based at least in part on comparing the system requirements for the simultaneous communication to the system parameters that indicate the capabilities of the software and/or hardware installed on the SDR-enabled wireless device; and

d) conditionally enabling simultaneous communication according to the first and second wireless protocols based at least in part on a result of the determining of act b).

12. The method of claim 11, wherein receiving said request for performing simultaneous communication of the first and second wireless protocols comprises receiving a request of a first provider for performing communication of a first wireless protocol and thereafter storing information regarding whether the device is in communication via the first wireless protocol.

13. The method of claim 12, wherein receiving said request for performing simultaneous communication of the first and second wireless protocols comprises receiving a request of a second provider for performing communication of a second wireless protocol.

14. The method of claim 12, wherein receiving said request for performing simultaneous communication of the first and second wireless protocols comprises receiving a request of a second provider for performing communication of a second wireless protocol and thereafter transmitting test signals simultaneously using the first and second protocols to determine whether the simultaneous communication can occur.

15. The method of claim 11, wherein comparing the requirements for the simultaneous communication to the system parameters comprises comparing the requirements to system parameters on communication software installed on the SDR-enabled wireless device.

16. The method of claim 11, wherein comparing the requirements for the simultaneous communication to the system parameters comprises comparing the requirements to system parameters on communication hardware installed on the SDR-enabled wireless device.

17. The method of claim 11, wherein merging the first protocol requirements and the second protocol requirements to yield requirements for the simultaneous communication comprises combining the first protocol requirements and the second protocol requirements.
