General Note:
1. All licensed modes share the same antenna part and cannot transmit simultaneously.
2. The worst case WLAN reported SAR for each configuration was used for SAR summation, regardless of whether the WLAN
channel has WiFi Direct and Hotspot capability. Therefore, the following summations represent the absolute worst cases for
simultaneous transmission with WLAN.
3. When the device operates in head/hotspot/body-worn, cellular TX power has 2 power table associated with WiFi-ON (power table 1)
and WiFi-OFF (power table 2). Cellular SAR associated with power table 1 was used for analysis of simultaneous transmission with
WLAN and BT, associated with power table 2 was used for analysis of simultaneous transmission with BTonly.
4. The Scaled SAR summation is calculated based on the same configuration and test position.
5. Per KDB 447498 D01v06, simultaneous transmission SAR is compliant if,
i) Scalar SAR summation < 1.6W/kg.
ii) SPLSR = (SAR1 + SAR2)^1.5 / (min. separation distance, mm), and the peak separation distance is determined from the
square root of [(x1-x2)2 + (y1-y2)2 + (z1-z2)2], where (x1, y1, z1) and (x2, y2, z2) are the coordinates of the extrapolated peak
SAR locations in the zoom scan.
iii) If SPLSR ≤ 0.04 for 1g SAR, if SPLSR < 0.1 for 10g SAR, simultaneously transmission SAR measurement is not necessary.
iv) Simultaneously transmission SAR measurement, and the reported multi-band SAR < 1.6W/kg.
