UMA vs. Femtocell
And TMO did it because they're well aware their coverage is lacking. So UMA was a simple way to use something most everyone already has in their home to better their coverage.
And there's no way (as yet) to stop VZW femtocell from letting other VZW users leach off your broadband. 😡
as far as mooching off other peoples network, i have no solution for that. it's one of the things that's going to need to be worked on over time. but just like wifi range it usually extends to your house and mabye nextdoor too. nothing beyond that usually.
now it's almost a hassle trying to get a customer to take the t339 when they have their heart set on a gravity with reception in their home being the deciding factor.
WOW! 😲
Reception would be the most important factor. Then I'd worry about the phone.
And the Gravity, yuck!
UMA can be used world wide, but the customer still gets charged international roaming cause the of the IP address that the wifi registers so it's more or less pointless.
Is there a definitive answer?
