For me I went from roughly
which was good enough to increase from about 20Mbps to max peak so far of 51Mbps, this was sticking the SXE LTE Kit outside. Im about 1 mile from tower, but in a slight dip with taller houses (albeit detached, so plenty of gaps in air space) in the way.
What was really weird is I first installed it roughly where I got the best signal the other day leaning out of a bedroom window, but I just couldnt't repeat this in a fixed position, turns out I literally moved it 3" left a bit and signal improves, I guess it found a slither of better signal though the houses!!
I'd be intrigued what RSRP and SINR figures people get who are getting north of 60+Mbps. I guess my speed is signal related not congestion, although with a lack of anything but ADSL round here, theres hundreds of houses who may be giving up like me and choosing the mobile option.
