At my telco day job, we have several circuits to cell sites; most are 100-200 Mbps capacity on 1G phy, but they all aggregate to a pair of GigE waves to their MSC. Rural north-central Wyoming.

They're moving to dark fiber or tubes of dark fiber. A Sprint tower can move 1.3 gigs, with some doing more.

Subject: [AFMUG] Typical Cell Tower bandwidth requirement

I was talking to a Spectrum employee yesterday as he was installing a 1gig fiber circuit for me and he started talking about how un-common it was to be seeing a 1 gig DIA circuit installed so i said well what about the cell phone towers, don't those all have a couple gigs to them and he said. "Oh no those usually only have 100meg fiber feeds to them." I was like whoa, thats all? And he said "yeah all the Sprint, T-mobile, and At&T towers that he's been to are all like 100meg and he's like usually the Verizon ones are about 300meg circuits."

Does that really sound possible that a cell tower is only using that much bandwidth? We are pretty rural here county population is only 45,000 and the city populations are only about 12,000. Can this really be true? And if so why can't a WISP sell a backup circuit to a cell tower with some Air Fiber equipment?
