What is 5G? | POTs and PANs: What all of this means is that a 5G network is going to require a lot more cell sites packed closer together than today’s network. That has a lot of implications. First, it means a lot more investment in towers or in mini-cell sites of some type. But it also means a lot more fiber to feed the new cell sites. And those two factors together mean that any 5G solution is likely to be an urban solution only, or a suburban solution only for those places where a lot of users are packed tightly together. No wireless company is going to invest in a lot more 5G towers and fiber to cover suburban housing sprawl and certainly nobody will invest in the technology in rural areas.Doug Dawson provides a good explanation of why the economics and technology of telco wireless service -- including the next generation 5G service -- can't provide an economical solution compared to fiber to premise. Aside from spectrum providing inadequate bandwidth for growing household demand that only fiber can satisfy, telcos would have to invest in a lot more cell sites to feed the network, which as Dawson explains can't pencil out except in very densely populated areas.
We already have a cellular wireless divide today with urban areas getting pretty decent 4G and rural areas with 3G and even some 2G. Expect that gulf to become greater as high-bandwidth technologies come into play. This is the big catch-22 of wireless. Rural jurisdictions have always been told to wait a while and not clamor for fiber because there will eventually be a great wireless solution for them. But nobody is going to invest in rural 5G any more than they have invested in rural fiber. So even if 5G is made to work, it’s not going to bring a wireless solution to anywhere outside of cities.
