This letter outlines the compliance strategy employed by Sepura for the SC2024 FCC/ISED certification, necessitated by component changes. Specifically, the Bluetooth/Wi-Fi module (previously LBEP5CLWTC-631) has been replaced with the LBEE59B1LV-278, and the GNSS module (Ublox M8) has been updated to Ublox M10. The new BT/Wi-Fi module is already certified under FCC ID: XX6LBEE59B1LV and IC ID: 8739A-LBEE59B1LV.
The document details the testing approach for Bluetooth, Wi-Fi, and TETRA functionalities. Bluetooth testing leverages manufacturer data, supplemented by radiated spurious emission and output power checks. Wi-Fi testing involves complete re-evaluation due to software-based power reductions. TETRA testing, while not involving circuit changes, undergoes full re-testing due to accreditation scope changes at the testing lab. The letter also addresses simultaneous transmission capabilities, unintentional radiator testing, and RF exposure calculations, ensuring comprehensive compliance with FCC and ISED regulations.
