When my isp setup my internet connection I didn't pay too much attention to the details of the whole system. Now I am interested in better understanding what kind of setup my isp created. I have no modem and yet I am able to use a router or a hardwired connection using a 426ft cat-5e cable from the wall to whats called a ubiquiti poe adapter. I have a dish on my roof to get internet access from my isp, presumably the cable goes to that. The isp is a broadband service. I don't understand though how I can have internet without a modem, they told me that the poe adapter acts as a modem.
I am thinking of getting a better poe adapter to facilitate faster throughput so I may need to know how to classify this sort of setup for optimal research.
