GPS Antenna is showing yellow on new Nokia microcell. Cant get it to go white

Just installed new Nokia booster for a friend at her beach house could not get the GPS light to go white. Have powered down but no change. The equipment cabinet is in a closet and is nowhere near a window so there will never be a possibility for the antenna to be placed in the preferred location. What does the GPS do? Does it have anything to do with 911? What alternative options are there to get this resolved?

@73blazer Read my Tech Guide, link is in my sig line. The information posted above is partially correct.

E911 is an FCC requirement so the physical location of the Cell Booster must match the GPS coordinates. For registration/activation the GPS antenna needs to be on a window or window sill. Once activated, and you receive the message from AT&T that you are good to, you can try to place the Cell Booster back in the closet to see if it will still work but you should leave the antenna connected. Signal propagation/strength will be an issue of the Cell Booster is in a closet.

The new LTE FemToCell comes with a GPS antenna on a wire so even if the equipment is in a closet, you should be able to get the antenna near a window. The antenna that comes with it is designed to be stuck to a window, flaat side facing out, or "the sky" . If you need to extend it, look for RG174 coax with mmxcx male to mmcx female terminations.

The GPS is used for many things, not the least of which is to verify the location you typed in while activating, this will determine e911 services as well as what towers should be in it's "neighborhood" if any are too close it will tone down it's radio. It also determines what bands it can broadcast that are legally allowed to operate in that particular area.

Appreciate the info @73Blazer and OttoPylot. After studying/researching your comments, I read that once you complete a successful initial activitation, meaning all the lights burn steady white, the GPS coordinates with the tower and 911 are locked.

Then, as per AT&T tech support, I can move everything to the equipment closet where the antenna can be mounted on the wall and all will be fine. Any thoughts on that?

Incidentally, in addition to the GPS light not turning white, the 4G LTE light never even blinked so that's an issue too. 

Worst case, who would you call to have an in-home tech specialist handle this?  I'm not going to be back to my friends house for some time and they aren't good with this stuff. They also are not spring chickens and and navigating the equipment closet can be a physically difficult for them.

@PaulaBen  There is no in-home tech support that I am aware of. Please read my Tech Guide. From my Cell Booster Technical Guide:

GPS Lock/GPS Lock Achieved: If the GPS light is a solid white, then that means GPS Lock has been achieved. If the GPS light is a solid orange, that means that Lock hasn't been achieved but the unit can still be activated using the default mechanism to find the macrocell (tower) for location verification. If location verification fails it means that the Cell Booster cannot achieve a lock or find a local macrocell (tower).

Once you have successfully activated the Cell Booster, you can try to move it to the closet and hang the antenna or mount it on the wall. That may work, until AT&T pushes an update/maintenance or you lose power. In either case, the Cell Booster will reboot, and part of that process is covered  in the Initial Activation section of the Guide. The location will then need to be re-verified, either by GPS or by connection to the nearest tower. If the unit is in a closet, then that might not happen until you move the antenna close to the window again. You can find extension cables for the antenna and that too is covered in the Guide.

If the LTE light is a solid white along with the other lights, then you are good to go and should have received an email or message from AT&T stating that. The LTE light will only flash if a phone has or is connecting to it or you have reached the maximum number of simultaneous users (8).
