Electronic – GSM modules and ICs

gsmintegrated-circuitmicrocontroller

I have been looking for GSM modules and found some very interesting devices, such as the SIMCOM 7100C and similar.

The "problem" I have with these is that they are very high-level, that is, you can directly connect an LCD display or a keypad to it and it even includes some ARM processor.

I have been thinking, the "core" functionality of these modules must be available in some simple integrated circuit. I have on SIMCOM's website that the 7100C is built around Qualcomm MDM9215. But I couldn't find much about it.

  • What do I look for (what are these ICs called)?
  • How would one go about building a GSM solution such as the SIMCOM's IC?

Thanks!

Have a look at Gemalto (http://www.gemalto.com/m2m/solutions/modules-terminals) and Sierra Wireless (http://www.sierrawireless.com/products-and-solutions/embedded-solutions/).

Do you really need LTE? The modules are about 4x the cost of 2G. That is part of the reason the SIMCOM module is so complex.
