Abstract

Systems, methods, apparatus, processors and computer-readable media include a radiated testing module that executes a predetermined radiated performance test on a wireless device. The test dictates various performance-related parameters to measure and log at each of a plurality of predetermined positions. Further, the wireless device receives synchronization information operable to enable synchronization between the logged measurements and each of the positions. The synchronized log allows the wireless device, or another apparatus, to determine a radiated performance characteristic based on a predetermined analysis protocol. Further, the described embodiments allow for the determination of several radiated performance characteristics in a single test, using a single, unaltered wireless device.

Claims

or (b4) combinations thereof and

the step selected from steps consisting of (c1) recording synchronization data, in the test log, on the wireless device, corresponding to a respective position for each one of the plurality of positions and further corresponding to each of the measured signal characteristics, (c2) providing synchronization data to another device for recording in a test log on the another device or (c3) combinations thereof.

2. The method of claim 1, further comprising generating the radiated performance characteristic corresponding to a predetermined position associated with the plurality of positions based on the measured signal characteristics and the synchronization data.

3. The method of claim 1, further comprising wirelessly receiving the synchronization data at the wireless device.

5. The method of claim 1, further comprising applying a predetermined analysis protocol to the measured signal characteristics and the synchronization data to generate the radiated performance characteristic.

6. The method of claim 5, where the measured signal characteristics comprise gain values, and where the action of applying a predetermined analysis protocol further comprises:

determining a maximum one of the gain values and the corresponding maximum gain position;

determining a maximum radiated sensitivity at the maximum gain position; and

determining a total radiated sensitivity of the wireless device based on the maximum radiated sensitivity.

7. The method of claim 5, where the measured signal characteristics comprise radiated power values, and where the action of applying a predetermined analysis protocol further comprises:

determining a maximum radiated power value for each one of the plurality of positions; and

determining a total radiated power metric for the wireless device based on the maximum radiated power values.
