Network extension antenna lte modem. Is there such a thing?

Question

Computer networks

It is necessary to take the antenna from the modem to the roof, pulling a new cable is not an option, but there is a local network. Are there ready-made solutions? Something like: modem <-> some device with sma connector <-> lan <-> some device with sma connector <-> antenna

Answer 1

modem?

Answer 2

hyhyg, well, technically, it's probably possible to convert an analog signal into digital form by installing a terribly expensive high-frequency ADC :) compress this signal, because the data stream from the ADC will be crazy on an expensive high-speed DSP, send it via a lan cable, unclench it there (+ one more DSP) and convert to analog (+ high-speed ADC) and send and broadcast. plus the same set for the reverse channel :)
I greatly exaggerate the picture of the resulting piece of iron,
but still, isn’t it easier to put a very inexpensive router with a lte modem or usb whistle on the lte on the roof and stretch the cable into the house.
By the way, you can take a modem with a coaxial output and connect a high-quality wave channel antenna to it or put a usb whistle into a parabolic focus or a bunch of other options.

Answer 3

If it is possible to bring 220 to the attic, get a router with modem support. It is put in the attic in a sealed, insulated case (you can just insulate the box for the electric meter yourself, add a self-regulating heating cable). And from it already remove the antenna.

Answer 4

Take this or that to the roof - powered by POE

Answer 5

Thanks to all. The described solutions with a rooftop router were considered naturally (this is how everything was eventually implemented), but due to the fact that there is a need to use a SIM from another operator, I wanted to keep the modem closer, but alas.
