Re: T-Mobile is the fastest 4G LTE network in US (according to 6 billion OpenSignal reports)

Any chance they can supply 12V versions? I should ask the local

> T-Mobile shop...

You have to agree not to "move" them around without T-Mobile permission, but I get your drift that they'd be great inside a car.

Let me look at the power supply, which is really all that matters.

The repeater (which basically just picks up a weak signal and amplifies it) has a power supply whose secondary is 12 VDC at 1.5 Amps, which is

*perfect* for a cigarette-lighter adapter, don't you think?

The femtocell, which has to be attached to a router, has a power supply secondary output of 12 VDC at 2.0 Amps - which is also within the range of a car.

Of course, they work in hotels too, and camping, so, you *could* get away with it - but I wonder if they could tell?

For the repeater, they might not be able to tell, unless the repeater itself sends a signal *back* to the tower since I've already seen using the debugging tools on the Android phone that the repeater just repeats the

*same* tower information to the phone.

That is, the Android debugging tools I've used show clearly that the repeater itself, does not seem to provide the phone with any other number but the nearest (strongest) unique tower number.

However, when my Android phone picks up the femtocell, the *unique* number of the femtocell *is* displayed on the phone (this test can't work on iOS even though the iOS Apple Apologists "say" it can, sans any proof).

In summary, for the free T-Mobile cellular repeater: a. The free repeater use 12 volts DC input at 1.5 Amps of current b. Hence, the repeater could be used in a car, theoretically (I assume) c. Certainly it could be used camping or at a hotel d. But would T-Mobile know that you moved it? e. Maybe not. The repeater just strengthens the local tower strength f. Does the repeater report back to T-Mobile? I don't know.

In summary, for the free T-Mobile cellular femtocell: A. The free femtocell uses 12 volts DC input at 2.0 Amps of current B. But it needs to be connected, via Ethernet cable, to 'something' C. In a car, I don't know of that 'something' to connect to (do you?) D. Certainly it could be used camping or at a hotel if you have an AP E. But would T-Mobile know that you moved it? F. Probably. The femtocell has a unique tower number & your IP address G. However, you can change your IP address so, maybe T-Mobile won't notice? H. But the IP address has a "geolookup" location - which they 'could' see

Dunno enough about this, but I added sci.electronics.repair because smart people like Jeff Liebermann know this stuff far better than I do.

All I know is that T-Mobile gave me both, even though they normally only give you one, because I have a large house and I get my Internet over the air via WISP which Jeff Liebermann is intimately familiar with, so they gave me both, for redundancy, for free, with zero deposit required.

only if you have a very, very long ethernet cable, because:

Don't feed the troll... No matter how accurate, brilliant and thoughtful your riposte, it cannot understand it, and the rest of us don't care.

pfjw, aka Snit, "is" the troll...

Just watch.

pfjw has absolutely zero capability to answer the on-topic question.

Watch. And realize that pfjw not only *is* Snit, but he's the troll here.

Exactly. Does it have a wall-wart with a USB socket? OTOH, I have a couple of converters...

Why would they bother? Why would they even care?

I have USB and earphone sockets, but no ethernet :-( Does it normally plug into 110V with a wallwart? I have a converter. Doesn't solve the ethernet problem, though, which presumes a router :-( Never mind...

You'd think they'd provide a simple cigarette-lighter plug-in unit. It's to their advantage that you be able to connect with T-Mobile as often as possible -- otherwise you might choose Verizon. Maybe even a rechargeable battery-operated unit so I could phone from the ski slope :-)

Perhaps run a VPN on your phone. No idea how practical this is.

I NEED to visit the T-M store.

We should take this conversation over to the thread *just* for this topic.

This is a useful answer from you nospam, which I, for one appreciate.

Probably T-Mobile cares for the following reasons.

  1. I assume, as nospam did, that they have regulatory E911 constraints
  2. I assume they also have FCC radio-spectrum broadcast constraints
  3. In addition, I assume they gave the repeater to me for a reason and that reason was *not* to move it around but to garner coverage in my home which sits on a mountaintop quite a few miles away from the cellular towers.

Thanks nospam for being helpful.

BTW, Snit just responded in the s.e.r. thread, which you might find funny 
(he did it under the nym ("pfjw@aol.com" ); but it was 100% 
Snit. It's actually kind of funny.  But also sad. Here's the link: 

 
  Could a T-Mobile repeater & femtocell be moved to a new location outside the Santa Cruz mountains?
