This document from the Federal Communications Commission Office of Engineering and Technology Laboratory Division provides SAR test guidance for devices incorporating Long Term Evolution (LTE) capabilities. The procedures are compiled based on recent inquiries from grantees and test laboratories on how to test USB dongles and wireless handsets with LTE functions. As device implementations continue to emerge, further revisions to the SAR test requirements for LTE products may be necessary. These test considerations have taken into account the different factors and parameters, due to evolving designs, which could result in varying test configurations required to support RF exposure compliance.Read the document from the FCC.
