My first question is: according to my study book, 802.3Z is the only Ethernet protocol that has fiber cabling, and a maximum length of 5000 meters. Why is that? Why isn’t fiber better suited to faster speeds like 10 Gig Ethernet, and why is it the only standard that uses fiber cabling?
My second question: From a topology standpoint, how does mobile internet work? As in, are the towers just massive WLAN access points? If so, is every switch from tower to tower interconnected instead of using routers? I remember having this question a bit ago and I was totally perplexed. I’m hoping one of you guys could shed some light.
EDIT: nevermind, I misread the first part and the second part wasn’t a very good question in the first place lol.
