AVT9152 SAR testing?

gmonroe
gmonroe over 2 years ago

I see  in the FCC filing that the AVT9152 is not supposed to be used within 20cm of the body.  I know this is a limit that triggers SAR testing.  Can anyone tell me if SAR was just not tested on this device or if there were problems with it?  We need to be installed closer than that.  I want to make sure that we could move forward with our own testing as necessary as opposed to knowing that it will fail if we do test.

    AVT9152 had gone through Radio Exposure Evaluation (FCC 47 CFR Part 2.1091) for its embedded BLE module + antenna. Nordic's nRF9160 IC had also gone through FCC 47 CFR Part 2.1091. Based on the assessments…

    No testing related to SAR was done previously. Other than that, the module (in particular nRF9160) conforms to 3GPP spec, and had passed corresponding FCC and CE's RF emission tests.

    AVT9152 had gone through Radio Exposure Evaluation (FCC 47 CFR Part 2.1091) for its embedded BLE module + antenna. Nordic's nRF9160 IC had also gone through FCC 47 CFR Part 2.1091. Based on the assessments, AVT9152 (with nRF9160 inside) is safe to be used at a distance greater 20cm from a user.

    The module has not done SAR test as this depends on actual usage scenario - how the module is mounted in end device and its position to human body, type of LTE antenna and orientation, etc.

    Do you know if anything has been seen in prior testing that suggests it might fail?
