Startup delivers lowest power NB-IoT and eMTC baseband chip

December 06, 2017 // By Jean-Pierre Joosting
Vancouver-based startup Riot Micro has made its market debut with the Riot Micro RM1000 chip, which claims to be the industry’s lowest power baseband modem chip for the cellular Internet of Things (IoT) – reducing power consumption by up to 50 percent.

The baseband modem chip is built using an innovative approach that applies BLE and Wi-Fi architecture techniques to deliver a cellular IoT solution with the low power and cost levels characteristic of short-range wireless systems. The RM1000 is available now to module manufacturers and OEMs designing NB-IoT and eMTC systems including asset management, home automation, industrial, point-of-sale, smart energy, vending and automotive applications. 

To develop the the low-power, innovative design of the RM1000, Riot Micro assembled a team of engineers with extensive expertise in Bluetooth, Wi-Fi and LTE design to create an LTE PHY and L2/L3 protocol stack specifically optimized to meet the 3GPP release 13 requirements for Cat-NB1 NB-IoT and Cat-M1 eMTC. By providing granular control over system resources, the innovative hardware-based architecture minimizes active power consumption in all use cases. This design approach significantly reduces silicon area and active power consumption compared to alternative signal processor-based solutions.

“Riot Micro’s innovative approach, leveraging proven design techniques from BLE and Wi-Fi into the world of LTE, will drive down system cost and power. We want to enable cellular IoT mass deployment. That will require the cost and energy needs driven to similar levels as BLE, and our approach gets us there,” said Peter Wong, CEO of Riot Micro.
