Description

Stamp Cat1 is a compact LTE CAT1 data communication module, built-in with the SIM-A7680C module adapted to the LTE CAT1 frequency bands in China, supporting LTE-TDD/LTE-FDD wireless communication standards. The module integrates an SMA external antenna interface to ensure communication quality and signal stability. Compared to NB-IoT, CAT1 has stronger data transmission capabilities, with a maximum downlink rate of 10Mbps (uplink)/5Mbps (downlink). This module is very suitable for application scenarios that require data transmission rates (remote control/data transmission, etc.).
