would 5g completely replace 4g and you would have to throw your 4g phone away or 4 g would continue to exist for few more years?

5G fundamentally can't replace 4G because 5G signals have far, far less range. Like, by an unreal margin.

@BlueVeins why it has less rage

@mysteryespresso Higher frequency radiation, it doesn't go straight through most walls the way radio waves do.

When a wavelength is really short (such as the frequencies at the higher end of the spectrum), the waveform is so tiny that it can become easily distorted. This is why really high frequencies can't travel as far as lower ones.

This is one of the primary reasons why a microwave oven will not effect your next door neighbors reception even if shielding is an issue.
