Forget the smart phone - at least if it's un-rooted Android. I'm not
sure how the default time sync is done, it's either by

So, some electronics with a micro controller that do the actual
Check out the ESP8266 based wi-fi modules. They are dirt cheap (< $5) and tend
to have excellent range. Sparkfun has some that are nice (and more expensive)
that break out all the processor pins. The ESP8266 is a 32-bit processor with
on-chip wifi. The ESP8266 are now supported in the

A couple of us were kicking around the idea of a low cost JT65-like HF
modem implementation, which requires that the station be synchronized to
1 second.

I don't have a cell phone to experiment with, but I do have a Raspberry Pi
connected via WiFi. Ping times are a bit over 3
