      How does the signal from your phone travel the distance between your phone all the way to the cell tower?

      @Oudouch Abdelaziz I wasn't aware phones met the power requirements necessary to broadcast a signal more than 9m (30ft).

      What is the role of antenna in analog communication??

      Are not the waves first carried by Coax to the base station. Then transformed to light waves over fiber?!

      Mario I think we still use Coax from base to antennas in Norway at least :)

      Yes. In the past. But you're living in the future now 😉. It's all fibre now to allow for increased bandwidth for faster internet access and to future-proof it as well for even faster speeds in the future. Coax has physical limits that fibre doesn't, so it's not very good future proof
