In the latest edition of the Ericsson Mobility Report, the forecast for cellular IoT increased significantly, almost doubling to 3.5 billion connections for 2023. The report cites large-scale deployments in China and increasing interest in eNB-IoT and Cat-M1 cellular IoTstandards as the catalysts for 30% CAGR between 2017 and 2023.
CEVA-Dragonfly NB2 claims to be the first licensable Rel14 compliant eNB-IoT system and builds on the success of CEVA-Dragonfly NB1, which has been widely licensed for a range of use cases and emerging end markets, including smart cities, transport and logistics and consumer electronics. It is centered on the CEVA-X1 DSP/control processor featuring an enhanced Instruction Set Architecture (ISA) and provides a unified processor environment for both physical layer and protocol stack workloads. The IP also includes a highly-integrated, worldwide enabled RF transceiver, a power amplifier (PA) and all the associated hardware and software modules required to develop a complete eNB-IoT product, ensuring the lowest possible bill-of-materials (BOM) in the process.
In addition to the performance improvements enabled by Release 14 including higher data rates and lower latency, CEVA-Dragonfly NB2 features a range of enhancements to ensure higher performance, added functionality and increased security for NB-IoTapplications compared to its predecessor. A new power management solution, complete with intelligent sleep mechanisms ensures ultra-low sleep power consumption of a few microAmps, further improving the battery life critical to every NB-IoT device. The enhanced RF design is already silicon-proven at 55nm and 40nm processes, further lowering the entry barriers for customers with no previous cellular expertize to enter this burgeoning market. CEVA-Dragonfly NB2 also includes the fully-optimized physical layer and protocol stack firmware designed for Release 14 Cat-NB2. The addition of an on-chip embedded flash memory and controller now allows full NB-IoT design on a single die which further reduces BOM and power consumption.
For customers developing NB-IoT products that also require GNSS capabilities, CEVA-Dragonfly NB2 includes a new power-optimized GNSS hardware package, with GNSS RF Receiver and multi-constellation digital front-end. This GNSS package speeds up both acquisition and tracking tasks by up to 8x compared to CEVA-Dragonfly NB1, enabling a host of popular NB-IoT use cases, including people, livestock and asset tracking, and geo-fencing.
