What are you asking?
Yes, distance can come into play, especially if you are a fair distance. A few hundred metres won't, but a few km's will. Strength of signal isn't as good. Think of a cell phone call where the signal is poor. Never very good. Now imagine you are listening for specific patterns, if there is a lot of noise it is difficult to hear the pattern, so they either have to re transmit, or lengthen the period of the pattern, in laymans terms. (This is not how 3G works, but should give you an idea). So far away means it requires more effort to get the message across, but up close, where it is clear, means easier and quicker to get the message across.
