Difference between types of 433 Mhz RF modules
This is pretty far off of answering your actual question, but I will offer some unsolicited advice. Those modules are ill-suited to mesh networking (if that's really what you're trying to do), as you're going to have to implement a full-stack protocol on top of them; they are just dumb ASK modulator / de-modulator pairs, no collision detection / avoidance built in or anything like that. You should consider using an FSK digital transceiver instead, e.g. HopeRF RF69HCW modules, or Nordic NRF24L01 modules. Or if you have the budget for it, something like an XBeee transceiver. You'll save yourself a lot of headaches by not interacting with such a low-level radio link, unless you really have a good reason.
