IP builds LTE Cat-M1 and Cat-NB1 blocks in cost-sensitive IoT SoCs

November 18, 2016 // By Graham Prophet
Signal processing IP provider CEVA, together with NextG-Com Limited (NextG-Com; Staines, UK), have 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 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. The solutions have been 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 100 MHz 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 [the company was formed as a spin-out from Infineon]. “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.”

 

“At CEVA, we’re at the forefront of LTE and 5G modem innovation, and the only end-to-end DSP supplier for cellular in the industry today, said Michael Boukaya, vice president and general manager, Wireless Business Unit at CEVA. “With the recent introduction of our single-core CEVA-X1 IoT processor, we leveraged this expertise to address the cellular IoT space and help drive this technology forward. Together with NextG-Com, we can offer our customers pre-integrated, dedicated solutions for low data rate LTE connectivity in any IoT device, from asset trackers through to wearalone wearables.”
