What type of 4g amplifier to choose for a city, high-rise buildings?

Question

Telephony

What amplifier would you recommend for a multi-storey building. I would like to amplify 4g to a speed of 10 megabits. Now the speed is 1. And are there any that can strengthen several operators at once. I want to take the antenna to the balcony

. I meant amplifiers that increase the entire signal in the room. An example is in the photo below. Will he help in the city, that is the question. And will it work with other carriers?

Answer 1

Yes, no all this wiring for the most part. What works.
A good modem is desirable with external antennas, or an access point with a built-in modem
. For example, this https://mikrotik.ru/katalog/katalog/hardware/wifi_...
Then install a program on your phone to check the signal strength. Walk around the apartment and determine the place where the signal is best.
Put the modem there. I personally catch only in the kitchen. There is a modem and a router. It’s frankly lazy to put it in the attic, although there is an antenna there.
