Sequans' Monarch 2 GM02S Module Successfully Completes Interoperability Testing for Use in Japan by NTT DOCOMO and KDDI

PARIS,Dec. 13,2021 -- Sequans Communications S.A. (NYSE: SQNS) announced successful completion of interoperability testing of its Monarch 2 GM02S module with NTT DOCOMO,INC.and KDDI,two of Japan's largest mobile operators. Monarch 2 GM02S is based on Sequans' second-generation Monarch 2 platform,which is an LTE-M/NB-IoT chip designed to support massive IoT applications including meters,trackers,sensors,and wearables. The Monarch 2 GM02S module delivers ultra-low power consumption,support for integrated SIM (iUICC),and a Single-SKU™ RF front end that supports deployment in any band worldwide. It is fully backwards compatible with Sequans first generation Monarch platform.

"Our IoT customers will benefit from the maturity and ultra-low power consumption of Sequans' Monarch 2 GM02S module," said Yoshiki Fujima,General Manager of Solution Service Department,NTT DOCOMO. "The module has powerful capabilities and it is a comprehensive IoT connectivity solution enabling device makers to launch new products quickly on our LTE-M network."

"Sequans' Monarch 2 GM02S module is one of the most advanced cellular IoT connectivity solutions in the market today," said Hiroshi Tsuji,General Manager of Service & Product Technology Department,KDDI. "It can be deployed in any band worldwide,ensuring success in IoT. We are pleased that Sequans' Monarch 2 GM02S module has passed our certification tests and is ready to support the design and deployment of new IoT devices on our network."

"Japan is one of the most exciting markets in the world for IoT and we are pleased that our Monarch 2 GM02S module can now support IoT developers and device makers in Japan," said Georges Karam,Sequans CEO. "Japan has great expertise in IoT segments such as smart city,smart home,wearables and other IoT-related tech and we look forward to seeing many new Sequans-connected IoT devices launching on Japan's mobile networks very soon.

Monarch 2 GM02S Module Product Description

Monarch 2 GM02S is the industry's most advanced LTE Cat M1/NB1/NB2 connectivity solution. It is based on Sequans' second-generation Monarch 2 chip platform,which is designed and optimized to support massive IoT. Monarch 2 provides significant improvements in performance and power consumption,while providing seamless migration for Monarch 1 customers because it is based on Sequans' existing LTE-M/NB-IoT protocol stack—one of the most mature and proven in the entire LTE ecosystem. Monarch 2 GM02S provides powerful support for integrated SIM (iUICC),enabled by its integrated high level EAL5+ secure enclave that is standards-based and GSMA-compliant,providing best-in-class security. Monarch 2 GM02S also includes Sequans' Single-SKU™ RF front end,supporting deployment in any band worldwide,for true global deployment capability. A low-power application MCU allows customers to port their own code into the module via a feature rich SDK. On top of its ultra-low power consumption,Monarch 2 GM02S utilizes a single rail power supply starting at 2.2 V,the lowest voltage supported by any LTE-M/NB-IoT module in the industry today.
