At the moment, the Huawei B525 router is standing on the windowsill of the window overlooking the nearby stadium, where the antenna from t-mobile is on one of the spotlights. From what I can see there is only 1800 MHz after the Orange changes. Earlier it was also 1800 MHz. Daytime transfers barely 0.5 Mbit. I have to combine with a transmitter change and with an external antenna. On the opposite side I have a transmitter on a CHP plant. I came up with a phone and a T-Mobile card under it and it makes 50 Mbit there. I just don't know exactly what the band is there. Probably different than here. 2700 I think I wrote to the side. Will we see what they write? Are there any android programs that show the transmitter bandwidth? The second thing is choosing the antenna. What to choose Of course, as I will know what frequency the transmitter.
