So is that why...

In other words - in the chart above - phones "listen" on the blue bands, and "talk" on the green bands. Vice-versa for towers (which in industry lingo are called "base stations".)


I am talking to someone on my phone on the 850 band when static starts to come in the listening end, yet when I speak the other party hears me fine.

Is that because my voice is being transmitted in the lower half of 850, therefore able to punch through buildings and go further, but the tower signal, coming on the top half of 850 can't quite connect as well?

Am I putting 2 and 2 together properly, or does the difference of 5-10 MHz not matter nearly that much?

The difference is actually closer to 50 MHz, but that's still not very significant when it comes to how well the signal penetrates walls, etc.

I think it's more just that the send and receive bands are separate, so if there's interference or something like that, it's only likely to affect one direction of the call and not the other.
