All radio spectrum (4g, 3g etc) is non visible as radio occupies a different part of the em spectrum to any of the forms of visible or non visible light. That's not to say that there ca't be concerns with 5g but it won't be light related.

My def would be optical radiation. Understand that many would say the entire em spectrum but even if we accept that there is still no significant difference between 4g and 5g that would cause you to expect human flourishing or catastrophe due to the migration. They're probably both slightly bad for you and 5g is probably slightly worse but not to the same degree that smoking or morbid obesity is bad for you.
Data transference requires energy, whether or not it’s visible is one thing, but it is real
