Inside our house I only usually get an H or H+ signal, or sometimes 3G but when I go outside, I get a fast 4G signal. I plan to buy a repeater so that I will get the same 4G signal inside.
I already have seen a repeater in an online shop and it's quite affordable at $50. However it says it is a GSM900MHz repeater.
My question is: can it detect the 4G signal outside and repeat the 4G inside our house?
