Grant Notes

Output power listed are maximum ERP for GSM 850, WCDMA Band 5, LTE Band 5/12/13/17/26, and 5G NR Band n5. Output power listed are maximum EIRP for PCS1900, WCDMA Band 2/4, LTE Band 2/4/7/38/41/66, and 5G NR Band n7/n38/n41/n66. It supports GSM, WCDMA, LTE (QPSK, 16QAM, 64QAM) and 5G NR Standalone and Non-standalone (CP-OFDM QPSK, 16QAM, 64QAM, 256QAM and DFT-s-OFDM BPSK, QPSK, 16QAM, 64QAM, 256QAM) LTE B2, B4, B5, B7, B12, B13, B17, B26, B38, B41, B66, 5G NR n5, n7, n38, n41, n66 Channel Bandwidth (5/10 MHz) for LTE B13, B17, Channel Bandwidth (1.4/3/5/10 MHz) for LTE B5, B12, Channel Bandwidth (1.4/3/5/10/15 MHz) for LTE B26, Channel Bandwidth (1.4/3/5/10/15/20 MHz) for LTE B2, B4, B66, Channel Bandwidth (5/10/15/20 MHz) for LTE B7, B38, B41; 5GNR n5, n7, n66, Channel Bandwidth (10/15/20 MHz) for 5GNR n38 Channel Bandwidth (20/40/50/60/80/90/100 MHz) for 5G NR n41; EUT supports Uplink Intra-band contiguous carrier aggregation CA_7C, CA_38C, CA_41C. 5G NR ENDC: DC_2A_n66A, DC_5A_n7A, DC_5A_n66A, DC_7A_n5A, DC_7_n66A, DC_26A_n41A, DC_66A_n5A, DC_66A_n7A; This device contains functions that are not operational in U.S. Territories; this filing is only applicable for U.S. operations. This device has integrated DXX, DSS, DTS, NII and PCE transmitters certified under the same FCC ID. SAR compliance for body-worn operating configurations is limited to the belt-clips, holsters or similar accessories that have no metallic component in the assembly and must provide at least 15 mm separation between the device and the user's body. End-users must be informed of the body-worn operating requirements for satisfying RF exposure compliance. The highest reported SAR values for head, body-worn accessory, hotspot and simultaneous transmission use conditions are 1.03 W/kg, 0.33 W/kg, 0.96 W/kg and 1.59 W/kg, respectively.
