In a low-noise environment, sure; this technique surely blows the SNR through the floor. Plus, being an OFDM signal you're probably going to lose all reception while the device is in motion.
Could you elaborate about why this would affect SNR? Do you just mean because the band is narrower, or is there a new source of noise? (Or something else.)
And if you don't want to code too much you can use esphomeyaml:
My guess is that by underclocking the PLL, you are slowing down to pseudo-noise signal, so it will have a narrower bandwidth. The 2.4 GHz carrier is generated separately, so is unaffected by lowering this clock. The overall effect would be that your RF signal is still centered in the same carrier, but the signal looks narrower.
Let's say the clock ticks at 100 Mhz.
So every second, the clock ticks 100,000,000 times.
Let's say the wifi broadcasts at 200 Mhz.
So every 200,000,000 (100,000,000 x 2) clock ticks, it sends something out into the airwaves - regardless of how much time actually passed in those 200,000,000 clock ticks.
Now let's slow the system clock down by half. It's now ticking 50,000,000 times per second - but still, every 200,000,000 ticks, it's going to send that signal out into the air.
Obviously those actual number are grossly misrepresented (because it's not sending something every 200,000,000 clock ticks, it's more likely sending something PER clock tick (or more accurately performing some function per available clock tick and sending it out at some predetermined number of clock ticks) - but this is just for visualization purposes)...and I could be way off - because maybe it's not the actual signal that is being slowed down, but the data inside of that signal - if that were the case, it just wouldn't be 2.4Ghz anymore. Either way, that sounds like a pretty basic why to me - Yes, this is explained below because the system uses two different phase lock loops...so it is not the signal itself, but the data in that signal that is slowed.
I guess the data signal is stretched and this gets modulated into a 2.4 GHz carrier signal? I don’t know how WiFi works ;)
But what I wrote above is based on random people’s comments. I don’t know what the rules are myself.
Too slow, and to an external observer, the pronunciation becomes unintelligible.
