Power Output is ERP for part 22 and 27(Below 1GHz) and EIRP for Part 24 and 27(Above 1GHz). This device has 1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz and 20 MHz bandwidth modes for LTE Bands 2/4/25/66; 1.4 MHz, 3 MHz, 5 MHz, 10 MHz and 15 MHz bandwidth modes for LTE Band 26; 1.4 MHz, 3 MHz, 5 MHz and 10 MHz bandwidth modes for LTE Bands 5/12; 5 MHz, 10 MHz, 15 MHz and 20 MHz bandwidth modes for LTE Bands 7/38/41. SAR compliance for body-worn operating conditions is limited to the specific configurations tested for this filing. Body-worn operations are restricted to belt clips, holsters or similar accessories that have no metallic component in the assembly and must provide a minimum separation distance of 10mm between the device and the body. End-users must be informed of the body-worn operating requirements for satisfying RF exposure compliance. The highest reported SAR for head, body-worn accessory, product specific(hotspot) and simultaneous transmission exposure conditions are 0.63 W/kg, 0.57 W/kg, 0.57 W/kg and 1.34 W/kg, respectively.
