That's not correct, I'm afraid.
The Nyquist-Shannon theorem concerns the relationship between sample rate and signal bandwidth when sampling continuous-time signals. It's got nothing to do with distance.
Essentially, it says that in order to be able to accurately reconstruct a sampled continuous-time signal you need to sample it at greater than twice the rate of the highest frequency component of that signal.
