Routine SAR evaluation refers to that specifically required by §2.1093, using measurements or computer simulation. When routine SAR evaluation is not required, portable transmitters without put power greater than the applicable low threshold require SAR evaluation to quality for TCB approval. One antenna is available for the EUT. The minimum separation distance is 5mm. BLE DTS: According to KDB 447498, no stand-alone required for BT antenna, and no simultaneous SAR measurement is required.
