Point to point network. Fun fact, you can invert an old satellite dish and mount a wifi antenna in place of the LNB and shoot your wifi for a mile or two this way. Back when high speed internet was still rare, hobbyists practiced different ways to extend networks to poorly covered areas. This was one of those ways. Then fiber was run across the country and everyone got their hopes up… to see the telcos say “out of money, sorry, keep using our dsl until we get more handouts to install the last mile.”
