-Wires and fibre optics are better for stable long distance communication when it comes to high bandwidth and high usage.
-High bandwidth radio infrastructure is extremely expensive and still reliant on terrestrial/ground wire elements to function.
-Massive data centers are needed for networking and routing data with the demands of the modern world.
That being said, look into meshcore networks. They are about the closest thing to what you are after that we already have, massive communication nets done by radio nodes and repeaters with consumer grade, off-grid tech.
