Re: 3g and 4g
If referencing conventional RF (Radio Frequency) propagation, the lower the frequency the longer the range and the higher the frequency the shorter the range, however, higher frequencies have better building penetration characteristics than lower frequencies.

This is only theory, in real live their are MANY factors such as your distance from the nearest LTE and or EVDO antenna, obstructions such as cars, trees, buildings and other sources of RF radiation that might interfere.
I hope this helps a little. My background is in Amateur (Ham) Radio but RF propagation and characteristics should be universal regardless of the service.
