After complaining about my 4G/LTE signal strength, T-Mobile sent me, this two-piece CELL-Fi signal booster cellular signal extender called a "T-Mobile Personal CellSpot 4G LTE Signal Booster":
Following the printed instructions, I set the "window unit" in an upstairs window, and it got LTE and two bars; and then I put the "coverage unit" as far away as I could, and it got a number of "9" (whatever that is supposed to mean).
My main question is whether this will work if I take it with me when I travel, or if it only works where I live (T-Mobile said they "set it up" for where I live, but that might just be for 911 purposes?). They also say I have to tell them if I move it, which implies that it will work anywhere. Does it?
My secondary question is whether I'm now feeding all my neighbors off of this Cell-Fi signal, if they're also on T-Mobile, and if that's a good or bad thing. (If it were my WiFi router, that would be a bad thing.)
My tertiary question is what the "9" literally means on the re-transmitter? The T-Mobile instructions say you want as large a number as possible, and, it further says that smaller apartments might end up with smaller numbers, but it doesn't say WHAT that "9" is supposed to be indicating.
Since I didn't ask for this unit (all I wanted was better signal), can you tell me some of the implications (good or bad) of using it at my home?
