The 3GPP recently completed the standardization of a new LTE-based narrowband technology to support the emerging needs of cellular-IOT devices. Known as Cat-NB1 (formerly NB-IoT), this new low data rate category will enable the development of ultra-low power, ultra-low cost solutions that can leverage the existing LTE infrastructure for a new wave of connected devices. However, in order to efficiently leverage the Cat-NB1 standard, a new approach to cellular SoC design is required, where low data rate transfer in very large time intervals is the goal. As such, solution designers might step out of their “comfort zone” and reevaluate existing modem solutions.

Naturally, CEVA already has solutions in this space. As the leading licensor of signal processing IPs for smarter, connected devices, CEVA together with NextG-Com Limited (NextG-Com) has introduced two pre-integrated narrowband LTE solutions designed to simplify the development of Cat-M1 and Cat-NB1 (NB-IoT) modems for cost-sensitive Internet of Things (IoT) applications.
The solutions incorporate the recently introduced CEVA-X1 single-core IoT processor together with NextG-Com's ALPSLite-M Cat-M1 or ALPSLite-NB Cat-NB1 protocol stacks, in a highly compact and power-efficient manner. Addressing the cost-sensitive nature of cellular IoT devices, the CEVA-X1 is capable of handling the full DSP and CPU processing loads for these modems, eliminating the requirement for a CPU controller in the system. Furthermore, the solutions have been carefully optimized to ensure smallest memory footprint, minimizing the requirements for costly embedded flash and static RAM. Ensuring maximum power efficiency for long life cellular IoT applications such as asset trackers or smart meters, the CEVA-X1 incorporates dedicated NB-IoT instructions, allowing it to operate at a clock speed of less than 100MHz for a complete Cat-NB1 solution.
"Cellular IoT offers huge potential in terms of the breadth of applications it will enable and the massive global scale on which these devices can be deployed," said Denis Bidinost, Chief Executive Officer of NextG-Com. "Our partnership with CEVA brings together their dedicated IoT processor with fully-optimized implementations of our Cat-M1 and Cat-NB1 protocol stacks to significantly simplify the integration of narrowband LTE connectivity into cost-sensitive, power-optimized IoT product designs."
