Ceva has designed a complete eNB-IoT IP solution that can serve a wide range of applications. The Ceva-Waves Dragonfly NB2 pre-integrates together a Ceva-BX1 processor, an optimized RF Transceiver, a baseband, and a protocol stack to offer a complete Release 15 Cat-NB2 modem IP solution that reduces time-to-market and lowers entry barriers. The Ceva-Waves Dragonfly NB2 is a fully software-configurable solution that can be extended with multi-constellation 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 firmware, and a protocol stack (MAC, RLC, PDCP, RRC, and NAS).
For broader foundry process selection, the Ceva-Waves Dragonfly NB2 solution can also be used with partners' RF transceiver or customer own.
