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.

Ampere is not a unit of charge. It's a unit of electric current (the rate of flow of electric charge). Unit of electric charge is coulomb. One ampere equals one coulomb per second.
Also, 100x100 mm? What's that about? That's awfully large, don't you think?
Really? Took a Chinese company's chip and marked it as their own? Waste of time; Qualcomm is really going downhill.
