Re: Depends... Are you saying that the unit has GPS unit with in the femento cell? Isn't that "cell" supposed to located in doors where there isn't a signal? This whole GPS thing sounds silly to me. |

This whole GPS thing sounds silly to me. GPS is used for, correct timing to allow handoff's to the main cellular network. And also for E911 purposes, if a PSAP only has Phase I E911 they will get the location of the Airave located within your house. If they have Phase II it will be used with the outside network + A-GPS in the Handset and GPS signal from the Airave to determine a more exact handset location quicker. |

This whole GPS thing sounds silly to me. I thought GPS units generally don't work indoors? Particularly if your house has bad indoor cellular coverage due to walls blocking the cellular signal, then you have NO chance of getting the GPS satellite signals... |

Hilliard, OH | I'm referring to the online "rumors" on the ATT femtocell having a gps built-in to specifically keep you from using it abroad, although it could conceivably be also used for 911 location, etc. |

It depends on why you can't get a cell signal. Since GPS is satellite based, the signal only has to be able to pass through the roof. On many structures, it can. Further, GPS is not as likely to be blocked by trees or other structures (though it could happen). Very often, problems with cell reception at home are because the signal is already poor outside, and only gets worse inside. GPS is less likely to have this problem.
If there are problems getting the GPS signal, it has an antenna cable that can be used to extend it and place it near a window, which should work unless there is some kind of coating on the window that kills the signal. |
