I believe the Millimeter wave technology(part of what they call 5G) is going to hurt smaller towns/communities. The carriers are already resistant to putting up(or upgrading) Cell towers in lower density/populated areas due to the cost/return on investment. Now we are talking about having to put transmitters on every 3rd or 4th light/power pole to get proper coverage. Sure that makes sense in highly populated areas but in smaller towns they are going to have to invest a LOT of money with little to no return on that investment.
I'm sure you're right, but that's always been the case. Getting high speed internet to smaller communities was always a cost/return estimation. When you have money for such projects coming in from a collective, such as the EU, then it's easier to roll them out because the collective bears the cost. That's why there are plenty of rural areas in Europe with access to high speed internet and a lot of countries made it a priority to deliver high speed internet to as many areas as possible.
