M-Cell Antenna

Does anyone know where to get the antenna that plugs into the M-Cell? I see there is a spot to screw one in and am thinking about getting one so I can put it in the closer with my WAP out of sight and running the antenna to the window.

Re: AT&T 3G Cisco MicroCell M-Cell GPS Antenna

I just received a reply to my request for further info about the antenna I was looking at, and indeed the vendor said that they're sending two connectors with their antenna system, one external and one internal. They also explained that the Microcell has no interaction with the AT&T cell tower so the antenna is either for GPS or to enhance coverage. Thus the good news is that there is a way to increase the Microcell coverage (which is exactly what I was looking for), and the bad news is that you may have to open it up to access the internal antenna jack...

Caution. If you open up the MicroCell there are a couple of tamper clips that will brick your MicroCell once they become loose. AT&T apparently has done this to prevent anyone from opening up their proprietary device and messing with it, and I doubt if they will replace a device that was opened and then "damaged".

Thanks for the info. Will the Microcell work again once the case is closed back? I don't think it's legal for any company to "punish" the end user for opening a device--all they can do is void the warranty I think...

I don't believe so. I've heard that once the clips come loose, it's difficult to get them back in their correct positions cause you can't really tell where they were in the first place. It's a tamper proof mechanism that voids your warranty so they aren't obligated to replace it. There's nothing illegal about it. Someone posted a couple of pics of the MC board that they removed from their MicroCell. Apparently his cat knocked it over and the clips came loose and rattled around inside and of course his MC stopped working (blinking lights, etc). I don't think AT&T replaced it because he opened it up and once you do that......

Dude.

 

I have 20+ years of UHF RF experience. It's a GPS antenna connector. A GPS receive antenna has a pre-amp in it, generally speaking. You can't transmit through a pre-amp without blowing out the pre-amp. Never mind that GPS doesn't operate anywhere near the frequencies that the Microcell uses (850 MHz or 1.8 GHz).

 

Shorting out that connector is a bad idea because the Microcell is supplying a voltage down it to power the pre-amp. If there's any impact on the operation of the Microcell, that's probably why.

 

I *promise* you, it's a GPS reception antenna port. Nothing at all to do with the 3G input or output.

Thanks for the helpful info to everyone. I agree that you have to be very careful when opening the Microcell or any other hi-tech device, not recommended for people without some technical experience. I will try to get one and open it up soon.

I would recommend you look thru this board and find the pics of the MicroCell insides and see if it looks like you'll be able to accomplish what you want to do. Otherwise your arrogance is going to cost you $200 (unless you buy one off of eBay or get it free) and all you'll end up with is an interesting paperweight.

Re: M-Cell Antenna

It pains me to say this as a retired AT&T employee but AT&T is screwing everyone with these MicroCell units.  When I moved to my current rural location 10 years ago my then AT&T cell phone was dead, no signal.  I dropped the service at that time.  I waited until a couple of years ago and finally heard that neighbors were now getting weak signals with Sprint.   So, I got a couple of their cell phones.  Still could not use them inside the house.  A neighbor, having the same problem, was made an offer of Sprints version of a MicroCell which he took.  After looking it over and the results he obtained I too acquired the same unit, as did another neighbor of ours.  The critical difference is that none of us had to pay for the unit or pay any charges whatsoever to use them. Sprint really came through for all of us.
I am in the process of assisting another neighbor with her AT&T MicroCell install. It is turning into an adventure.  Her address was not accepted by the online registration system.  After a long call with AT&T tech support they have turned this over to another group to do some kind of fudging in their system to make this work.  And they said it could take up to a week to get this completed.   Sprint had no such issue with any of our installs in the same "neighborhood".  I don't know what it is about AT&T these days but they continually seem to take the most obtuse track to accomplishing seemingly simple tasks.
Too bad. 
To keep this on topic, the free Sprint unit came with an external GPS antenna with a long cable.  The AT&T unit, as you are all aware, does not.   Again, too bad.

Yeah. Totally not true. Nice try though.
