Valley Stream, NY | Femtocell Isn't that simply a technology that T-Mobile uses with their @Home service. I have UMA phone and call through my router. Must say it's a win-win solution for me. While that way I get perfect coverage, it also helps with roaming.

This service broadcasts an actual GSM signal that your phone (or any other GSM phone) can use.

Valley Stream, NY | So wouldn't that be a similar concept? With the exception that GSM -> Internet conversion is done in the femtocell instead of headset? |

Similar idea, however your UMA service only works on the (very few) handsets that support it. Femtocell service on the other hand, can be used by every phone on the market today (except those by Nextel). Lets say you live in a cellular "dead zone", you put one of these there and any GSM/CDMA (depending on which femtocell you have) phone will work. Its a much broader application than the UMA service, but essentially does the same thing.

There's good with both services...
T-Mobile
1. UMA / WiFi service allows for any WiFi connection - which basically works great for cheap international roaming
AT&T:
1. Should be usable on any GSM/3G (assumption) phone that the carrier will allow to use
2. Not as 'portable', as its using carrier licensed frequencies and not 'open' WiFi. |

You are both correct in that they are very similar, and accomplish the same task. You also bring up a good point about (international) roaming via UMA. I think the real distinction is that femtocell service is simply an extension of the existing "cellular" network, whereas UMA is more of a supplementary service for specific handsets. Both are good, and I think that people should choose the solution that works best for them and their situation.
