Testing:
I fired up the Speed Test app on my T-Mobile supported Android phone in order to gauge the data speeds under three conditions... 1) Up on the roof with the phone straight up at arms length. 2) On the first floor of my home with the DataBlast YX550-VLTE-AWS unplugged. 3) On the first floor of my home with the DataBlast YX550-VLTE-AWS powered up.
The screenshot below details the results of this test, and subsequent testing tells me that they are repeatable, and while not 100% consistent, the general performance ranges of the three conditions are very distinct.
To summarize what we see in the image above, let's look at the individual results in text.
Download (higher is better):
Outdoors, on the roof, no DataBlast: 6626 kbps
Indoors, first floor, no DataBlast: 21 kbps
Indoors, first floor, ten feet from the DataBlast: 2842 kbps
Upload (higher is better):
Outdoors, on the roof, no DataBlast: 1278 kbps
Indoors, first floor, no DataBlast: 93 kbps
Indoors, first floor, ten feet from the DataBlast: 1738 kbps
Ping (lower is better):
Outdoors, on the roof, no DataBlast: 94 ms
Indoors, first floor, no DataBlast: 972 ms
Indoors, first floor, ten feet from the DataBlast: 64 ms
In the right position outdoors, you can get decent 4G signal, but you have to be at least several yards away from the house or apparently at a height of 30+ feet off the ground. Indoors you typically have zero signal, and the fact that I got anything for this test, despite being brutally slow, is a surprise and extremely rare.
From the data above we see that the DataBlast device does make a big difference, and can provide a very usable signal inside a building where there once was nothing. Of the three results recorded, the ping and upload speeds were actually better while using the DataBlast than when accessing the signal directly at its inconvenient location on my roof. Subsequent testing shows that the speeds and pings will bounce around from test to test, and that the two usable conditions will overlap quite a bit.
The main thing to notice is that inside the house the data rates have improved by a factor of about 135x on downloads and about 18x on uploads. We went from nothing to something pretty good.
