They mention that bandwidth is anemic at higher frequencies... so how well does this really work? And what kind of power is being pumped through those lines?
LTE is 700 to 2600 MHz, depending on the band. Wi-Fi is 2.45 (or 5 or 60) GHz. They’re all considered microwave and face similar signal integrity concerns in the same channels.
The prefix micro- in microwave is not meant to suggest a wavelength in the micrometer range. Rather, it indicates that microwaves are "small" (having shorter wavelengths), compared to the radio waves used prior to microwave technology.
Microwaves are a form of electromagnetic radiation with wavelengths ranging from about one meter to one millimeter; with frequencies between 300 MHz (1 m) and 300 GHz (1 mm).
