Abstract:
1. A method for signal measurement, the method comprising: in a wireless communication device: receiving a first signal via a first antenna at said wireless communication device during a test duration, the first signal being modulated according to a first communication protocol; during the test duration when the first antenna is under test, measuring a received signal strength of the received first signal at said wireless communication device; in response to the measured received signal strength, generating a characterization signal; concurrently with receiving said first signal via said first antenna during said test duration, modulating a second signal with the characterization signal so that the second signal indicates said measured received signal strength of said first signal, including determining a frequency of the received first signal, and selecting a frequency of said generated second signal so as to mitigate interference with said received first signal such that there is minimal or acceptable interference of the generated second signal from the received first signal, and modulating the generated second signal according to a second communication protocol, the second communication protocol being selected to be different from the first communication protocol; and concurrently with receiving said first signal via said first antenna during said test duration, transmitting said generated second signal via a second antenna during the test duration.
