ELI5: What is 5g and how is it different from former 4g lte etc?
gpt
If we think radio waves as sound, the previous generations were like putting one big speaker in the middle of your house to play back music for everyone. The music naturally doesn't reach every corner of the house as some walls might be thin and others might be thicker. When moving about in the house, you might not hear the music at all if you went to the cellar for example.

5G is like being able to have the big speaker and then putting smaller speakers in the rooms where the big speaker can't be heard loud enough.
