Qualcomm unveils power-efficient NB2 IoT chipset

1 min read

Qualcomm Technologies, has unveiled what it is calling a 'breakthrough' new product to drive the growth of cellular IoT. The 212 LTE IoT Modem is claimed to be the world’s most power-efficient single-mode NB2 (NB-IoT) chipset.

With power efficiency a top concern for IoT devices that have to last for years in the field, the 212 LTE IoT Modem’s power-efficient chipset architecture, requiring less than one micro-amp (1uA) of sleep current, allows for extremely low average power consumption.

To support a wide range of batteries and provide a longer life span of the device in the field, the modem couples ultra-low system-level cut-off voltage with provisions for adapting power usage according to varying source power levels – allowing end devices with power supply levels as low as 2.2 volts.

“The Qualcomm 212 LTE IoT Modem will help usher in a new era for a range of IoT applications around the globe, especially those requiring connectivity deep within buildings combined with low power use, like battery-powered IoT devices that need to operate for 15 years or longer in the field,” said Vieri Vanghi, vice president, product management, Qualcomm Europe. “It’s ultra-low power consumption, compact form factor, and low cost will greatly benefit OEMs creating the next generation of low-power IoT devices.”

The 212 LTE IoT Modem supports single-mode 3GPP Release 14 Cat. NB2 IoT connectivity, enabling extended coverage for delay tolerant applications on RF frequency bands spanning from 700MHz to 2.1GHz for Global roaming.

Housed in a single-chip solution including modem baseband, application processor, memory, RF transceiver with fully integrated RF front end, and power management units, the modem enables LTE modules below 100 square millimeters in size. Its high level of integration with few external components not only results in a low-cost Bill of Materials, but also facilitates quicker module design enabling faster commercialisation.

Due to an integrated ARM Cortex M3 application processor, and the native set of IoT data networking protocols, the Qualcomm 212 LTE IoT Modem can enable embedded IoT applications. Qualcomm Technologies is also launching an SDK for use with the Qualcomm 212 LTE IoT Modem, which is designed to support developers in running custom software on the integrated applications processor, while also offering pre-integrated support for cloud platforms such as the Microsoft Azure IoT SDK.
