| |  What Are the Limits (if any) of UMA?
Just as I asked...
What are the common points where you might not be able to count on UMA working at all?
For example, if I'm at home or at a T-Mobile hot-spot, that's a reasonable expectation of UMA working if needed right?
What about other situations? What if I'm tied into a wifi-signal at a hotel in the mountain (Internet works fine, etc)?
What if I were tied into a router that was tied to a satellite internet connection -- and I don't mean HughesNet -- like a Sabre Wideye BGAN terminal?
Anyone with any experience? What is the data rate when using voice over UMA (once in the cloud that is)?

I've used UMA all over the place: home, work, hotels, restaurants, cafes, libraries, Best Buy, etc. All of them support UMA unless the network firewall blocks IPSec, which you'll know by the white Wi-Fi BIS icon with no UMA indicator. That happened to me at a couple of trade shows.
I don't know the minimum baud rate for a UMA call, but I'd guess about 200kbps both ways.

Satellite is not a reliable enough signal to guarantee either @Home service or UMA.

Posted from my CrackBerry at wapforums.crackberry.com | That's what I was thinking. You think it lies more with latency or signal? Some applications I'm thinking will have a near perfect line-of-sight for signaling.

I've been able to get UMA everywhere except my college. The network there blocks a lot of voip applications and connections.

The occasional router prevents UMA from working well. My home connection, for instance, prevents me from making outbound calls on UMA (no carrier error) but I can usually receive incoming calls... though they are often too garbled to be worth it. I also don't get VVM notifications unless I disconnect.
Like most others here, though, I've connected at friends' and relatives' houses and not had any of these problems. Satellite internet would likely be an issue due to the latency, not so much the bandwidth.

I use it pretty regularly at home since my data connection here is pretty spotty. It works great for me, especially for uploads.

I am not tech savvy and I have a question regarding UMA.
When I am overseas, sometimes the hotel does not have wifi but have wired highspeed internet in the hotel rooms. Will I be able to use UMA if I bring my own wireless router and plug in the ethernet cable from the wall into the wireless router?
It's sort of making my own wireless internet, will this work?

By all means, if you can, take a wireless router with you and plug the ethernet in and you should be fine. I've done this myself and made calls back home over UMA and it worked great.
There are lots of travel-size wireless router for travel purposes as well.

The way it was explained to me was that provided you jumped on a wireless network overseas, the minutes you used would only come out of your bucket, not incurring international charges. This is what was changed, right? Or am I completely missing the point? I hope I am.
So, if I were to go overseas and turn off the Mobile Network option (leaving only the WiFi option), my calls would only come out of my bucket? Similarly, if I picked up a cheap wireless router (damn European plugs) and plugged it in when I'm overseas, it's only charged like a regular UMA call?

With the introduction of the unlimited plans, the $9.99 Unlimited HotSpot feature was rendered useless. Since that plan is no longer in effect other than grandfathered plans, all UMA calls are free, but are counted against your bucket of minutes.

Thanks for all the insight gang. Picked up a 9700 this afternoon and letting it get "settled". For setting up UMA initially, it seems that this needs to be started at home first, is that the case? The first wifi spot I tried to connect with (at work) wouldn't even connect to basic Blackberry services.
I'll be headed home shortly and I'll mess around with it there. Any tips or insights? I'm hoping to get this device optimized for a lot of wifi action and who knows, with all the traveling I'm doing if it can keep up, I might enjoy saving the money...
