Cavli Wireless C20QM

LTE CAT 4/2G Cellular Module

C20QM is a series of LTE Cat 4 modules, designed for IoT and M2M applications, that support 3GPP release 10. With its LGA form factor, it offers pin compatibility with the C10GS LTE Cat 4, C10GS LTE Cat 1/Cat 4 and C10QM modules, allowing for flexible migration. The C20QM module features integrated GNSS with Qualcomm® IZat™ location technology Gen8C Lite, providing precise and reliable positioning through GPS, GLONASS, BeiDou/Compass, Galileo, and QZSS. It supports VoLTE and SMS over IMS/SG/CS, along with a wide range of Internet protocols and industry-standard interfaces. The module comes in two variants: C20QM-EA for the Europe and Asia market, and C20QM-NA for the North America market. Additionally, with an optional integrated eSIM powered by Cavli Hubble platform, it offers global connectivity, reducing time to market. The C20QM module is well-suited for IoT applications such as asset tracking, e-mobility, data loggers, fleet management, and environmental monitoring.
