Overview

CEVA, in partnership with ASTRI, has designed a complete NB-IoT IP solution that can serve a wide range of applications.
The CEVA-Dragonfly NB1 pre-integrates together a CEVA-X1 processor, an optimized RF, a baseband, and a protocol software to offer a complete Release 13 Cat-NB1 modem IP solution that reduces time-to-market and lowers entry barriers.
The CEVA-Dragonfly NB1 is a fully software-configurable solution that can be extended seamlessly with GNSS and sensor fusion functionality.
It includes a reference silicon of the complete modem design, including an embedded CMOS RF transceiver, an advanced digital front-end, physical layer software, and a third party NB-IoT protocol stack (MAC, RLC, PDCP, RRC, and NAS).
