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?

- snazz 7y agoIsn't 4G a lower frequency than Wi-Fi? So if it works for Wi-Fi, it would definitely work for cellular.
- willis936 7y agoLTE 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.
- syedkarim 7y ago2 GHz is considered microwave? I thought microwave started at 10 GHz.
- qilo 7y agoThe 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).

- dusted 7y agoMy microwave oven is 2,4 ghz :)
- numpad0 7y agoJust fine. Leaky coax is used since late 3G era for underground rails and some high speed rails in Japan. Fast Ethernet level fast downlinks. Normal radios in tunnels interfere with own static waves or something.
- vxNsr 7y agoSo if I were building a house today would it make more sense to wire it with leaky coax or POE cat 6?
