The reality is 4G services have yet to reach most rural customers because it cost too much, and this is with 4G towers at maximum of fifteen miles apart depending on terrain and the number of customers.
Rural 5G wireless services would need installing radios every 3,000 feet at maximum, on towers and poles, back to the network backbone. They also require direct fiber connections and electricity to power their 5G radios.
Rural residents will be spared, because of costs, sub 6 GHz and millimeter waves which are not healthy, if you live in a rural area consider yourself lucky.
City population is packed into a dense area making 5G more cost-effective, better bang for the buck.
Aside, they still have not standardized 5G which is telling.
