Will you make new 3g, 4g modules like the eg25-g optimized for power and battery operated devices ? Maybe using a risc-v as coprocessor (or without one?)
Also, the more open source your modules are the more you will sell.

Well, we’ve done these before, aiming for 2+ years battery life, and we used a simple low-power micro running at low speed (like 8Mhz). It literally powers off the cell module when not in use, sleeps & wakes every 15 minutes (just the micro - cellular is still unpowered), does local sensor readings and decides if it needs to power up the cell module. The micro (in our case was an STM32-L152 used maybe 10uA while sleeping, 4 mA when awake & running at 8Mhz, and the cell module (either CAT1 or CAT1M) used from 200 to 800 mA when on & talking. Anyway, I think you are better off just using your own 2nd copro of your own choice. In fact, even for CATM1 it was humorous that our main-important MPU was 8Mhz ARM, and the ‘helper’ MPU in cell modules was a quad-core running at 200Mhz.

I should add, even as described above, if we power the cell module up a few times a day, 90+% of the battery life was lost to the sleeping MPU.
