Obrigado muito elmatador -

"We deploy GSM standard 1.8 GHz (DCS) instead of the 900 MHz. In the US you call them PCS and operate at 1.9 MHz."

However this wasn't exactly what I meant - I'm curious how the cell towers communicate among each other and their switching centers, rather than the well-known cell tower to handset RF path.

What have the systems you've come in contact with used? Are any using fiber deployed by utility companies, as mentioned by Frank?
