What equipment is needed to amplify the 4G signal?

Question

network hardware

During trips, in some places the quality of the Internet connection deteriorates noticeably (a 4G modem with a SIM card inserted into the USB port). I know that signal amplification equipment exists, but I don't know what kind of device is needed for this situation.

Answer 1

Signal amplification requires fixed equipment.
It is better to make sure that you can connect an external antenna to this modem model (or replace it with one), purchase an external antenna compatible with it. For example, https://www.citilink.ru/product/antenna-remo-bas-2...
If it happens on trips, then the solution will still be rather cumbersome.

Answer 2

Or, as they already said, an external antenna to the existing modem
. Or, even better, a portable 4G router with a good receiver / antenna (they usually have better quality and more than whistles)
Then the router can be placed on a window sill / balcony where reception is more confident, and from the bed to cling already on wi-fi
