Looks like the STM32W** series is STM32's wireless line, likely made famous by the Flipper Zero.
A lot of chips are coming in with these ISM band support (ie: unlicensed radio). TI's CC1352P7, this chip here, etc. etc. Its going to get a lot cheaper and easier to develop wireless applications with all of these microcontrollers coming out recently.
