I have two completely different types of CellSpot devices, both of which
say LTE.

Here is a photo of one type in my house, called "CellSpot" and "LTE":

that's the only LTE CellSpot I've seen. It has blinkenlights.

Here is a photo of another type alongside it, also called "CellSpot" and
"LTE":

Those are 4G LTE signal boosters which I've never seen before. They were
not on offer from T-Mobile when I asked about a CellSpot for my home.


In the basement (cellspot is in the garage) I have -78dB currently. If I
go into the garage it's about -60dB-65dB, IIRC.

That's absolutely astoundingly high cellular signal strength (RSSI).
All the articles put the range at -50 to -110 or -120dBm.

-50 is the maximum possible, and below -120 there is no signal.

Are you getting that from your T-Mobile micro tower?
How do you know? (Because that's the entire reason for this thread.)

my iPhone displays the dB in the upper left corner. I's at -78 again.
