Abstract

A method for conducting a radiated performance test on a wireless device comprising the steps of: establishing an interface from a test computer to the wireless device; establishing a data connection on the interface between the test computer and the wireless device; initializing and starting a timer for a predetermined interval on the wireless device; starting a test script on the wireless device; removing the interface during the predetermined interval; running the radiated performance test after the predetermined interval; storing a log of the radiated performance test on the wireless device; and analysing test results based on the log.

Claims

1. A method for conducting a radiated performance test on a wireless device under controlled test conditions, the method comprising the steps of:

establishing an interface from a test computer to said wireless device;

establishing a data connection on said interface between said test computer and said wireless device;

initializing and starting a timer for a predetermined interval on said wireless device;

removing said interface to said wireless device during said predetermined interval;

starting a radiated performance test result accumulation script at said wireless device after said predetermined interval;

subjecting said wireless device to said radiated performance test after said predetermined interval;

storing a log of said radiated performance test results on said wireless device; and

analysing said test results based on said log.

2. The method of claim 1, wherein said interface is a data cable.

3. The method of claim 1, wherein said interface is a wireless communications means.

4. The method of claim 1, wherein analysing said results includes:

re-establishing said interface;

re-establishing said data connection between said test computer and said wireless device;

retrieving said test log from said wireless device to said test computer; and

performing an analysis of said test log to provide derived test results.

5. The method of claim 4, wherein said step of initializing a timer includes said software tool sending a command to said wireless device.

6. The method of claim 1, wherein analysing said test results includes:

performing an analysis of said log on said wireless device to obtain derived test results; and

displaying said test results on said wireless device.

7. The method of claim 1, wherein said computer includes a software tool for communications between said wireless device and said computer.

8. The method of claim 7, wherein said step of establishing said data connection includes said software tool sending a command to said wireless device.

9. The method of claim 7, wherein said step of starting a test script includes said software tool sending a command to said wireless device.

10. The method of claim 1. wherein said step of starting a test script further includes loading a test script from said computer to said wireless device.

11. The method of claim 1. wherein said test script pre-exists on said wireless device.

12. A method for conducting a radiated performance test on a wireless device under controlled test conditions, the method comprising the steps of:

initializing and starting a timer from said wireless device for a predetermined interval;

starting a radiated performance test result accumulation script from said wireless device after said predetermined interval;

subjecting said wireless device to said radiated performance test after said predetermined interval;

storing a log of said radiated performance test results on said wireless device;

establishing an interface between said wireless device and a test computer;

establishing a data connection between said test computer and said wireless device;

retrieving said test log from said wireless device to said test computer; and

performing an analysis of said test log to provide derived test results.

13. The method of claim 12, wherein said interface is a data cable.

14. The method of claim 12, wherein said interface is a wireless communications means.

15. The method of claim 12, wherein said computer includes a software tool for communications between said wireless device and said computer.

16. The method of claim 15, wherein said step of establishing said data connection includes said software tool sending a command to said wireless device.

17. A method for conducting a radiated performance test on a wireless device under controlled test conditions, the method comprising the steps of:

initializing and starting a timer from said wireless device for a predetermined interval;

starting a radiated performance test result accumulation script from said wireless device after said predetermined interval;

subjecting said wireless device to said radiated performance test after said predetermined interval;

storing a log of said radiated performance test results on said wireless device;

performing an analysis of said log on said wireless device to obtain derived test results; and

displaying said test results on said wireless device.
