Riot Micro and Amarisoft have developed a low-power dual-mode NB-IoT and LTE-M module reference design that claims to enable 10-year battery life in NB-IoT user equipment, making it ideal for a variety of applications including asset tracking, smart city, smart home, and metering. The design features Riot’s RM1000 module design and Amarisoft’s AMARI LTE 100 software running on a compact software defined radio (SDR) platform.

The reference design is based on the RM1000 NB-IoT baseband modem and integrates all of the circuitry required to implement NB-IoT and LTE-M into a low cost 18x23mm form factor.

Supporting 17 global bands, modules can be built for IoT device OEMs that need a single-SKU design for deployment on global networks.

Modules based on the design will feature an ultra-low current in eDRX mode, allowing a battery life in excess of 10 years,  said the companies.

“We are excited to showcase the reliability and small form factor of the Amarisoft NB-IoT network connected to the Riot Micro module at MWC. Interoperability testing began a few months ago, and we closely collaborated to fine tune the NB-IoT software eNodeB,” said Amarisoft CEO Franck Spinelli. “The demonstration highlights how both Riot’s silicon and Amarisoft’s LTE test solutions are ahead of the curve in terms of supporting the evolving standards and application requirements of the global IoT market.”

The AMARI LTE 100 is a software suite including eNB, ePC, eMBMS gateway and IMS test server. The software allows end-to-end communication from up to 1000 commercial user devices. AMARI software components are 3GPP release 13 compliant, and are easy to install and configure through JSON config files. The system is ready for automation and administration using Amarisoft’s WebSocket remote API.

“Riot Micro is at the forefront of NB-IoT technology and required a testing partner equally advanced. With SDR and software flexibility, as well as exceptional customer support, Amarisoft stood apart in meeting this need,” said Peter Wong, CEO of Riot Micro. “The high quality of their software enabled quick validation of the interoperability of the RM1000 to address the needs of global IoT networks.”
