Qualcomm has launched the 212 modem, a new chipset for NB2 bands that needs as little as 2.2 volts (V) to function. This may be advantageous for internet-of-things devices that need to keep going on ultra-low power in the long term. It is also small enough to allow for connectivity modules measuring 100 square millimeters or less.

Qualcomm has launched its new 212 modem for NB2 (NB-IoT) LTE bands. It is designed with the longevity of connected IoT 'things' in mind. To that end, it enables components to survive on as little as 1 micro-amp (uA) of current and as little as 2.2V. Therefore, the resulting devices are more likely to last on their batteries for years (perhaps up to an estimated 15 years) at a time.

The Qualcomm 212 modem supports single-mode 3GPP Release 14 Cat. NB2 for IoT. It also packs a baseband memory, RF transceiver with a fully integrated RF front end, power management units and an ARM Cortex M3 application processor into its form-factor, rated for LTE modules of 100mmx100mm in size. 

The Cortex M3 is present to support custom software that IoT developers may wish to build. In addition, Qualcomm has indicated that it has pre-integrated support for more established  platforms, including the Microsoft Azure cloud IoT SDK, in the works for the new 212 LTE modem.

I became a professional writer and editor shortly after graduation. My degrees are in biomedical sciences; however, they led to some experience in the biotech area, which convinced me of its potential to revolutionize our health, environment and lives in general. This developed into an all-consuming interest in more aspects of tech over time: I can never write enough on the latest electronics, gadgets and innovations. My other interests include imaging, astronomy, and streaming all the things. Oh, and coffee.
