I decided I needed to get rid of Comcast.
I heard I was in one of Sprints 4g New England deployment areas.
It was real easy to get and setup the 4g modem.
It worked well for internet browsing right out of the box.
It didn't work well for ooma tunneling though.
"VOIP Speed Test" results didn't look good.
Actual use of ooma over wireless boadband was very bad.
I emailed ooma and the responded with:
(Please know that Internet connections such as dial-up, wireless or satellite
connections are not recommended with Ooma as you may experience voice quality
issues.)
After that I called Sprint and they updated serveral areas of my CPEi25150.
They also said one interesting thing.
They said that the modem was more or less an intelligent antenna.
Hmmm.
With that I treated this modem just like any other antenna.
I put it up as high as possible in one of my upstairs rooms and adjusted the position of it over a couple of days till the signal strength was as high as possible.
And that seems to be 2-4 bars.
Usually 3.
But know it works perfectly.
Yes ooma Hub works perfectly with Sprint 4g WIMAX.
Goodbye Comcast.

Great to hear. Unfortunately, WiMax (as Sprint and others call it 4G) can only do about 4Mbps down and a few hunderd Kbps up in reality. You'll miss Comcast's speed so you'll probably be looking for another ISP like fiber soon.

The real 4G (LTE) that Verizon and AT&T are deploying will be uber fast compared to Sprint and Tmobile's fake 4G...but still not today's cable internet speed.

Shugrue: You sound like you’re one of the lucky ones. I mean having Sprint’s wireless 4G in your area. The Motorola CPEi25150 modem looks like a neat device. I know that some of the larger companies are using wireless data lines when travelling along with portable VoIP devices for phone communications. So it's the comming thing. If you don’t mind I’d like to ask a question. What are your Sprint wireless 4G upload and download speeds as tested by speedtest.net?

Actually none of them are really 4G per the true definition. LTE Advanced will be true 4G but we won't see that for a while yet.

Of course speed is not the issue as far as VOIP goes.

Are you using Comcast? If so, how do the stats look when you test using the g.711 codec to various parts of the US here? http://myspeed.visualware.com/indexvoip.php I'm curious.

With regard to my earlier post...

I guess I can't say goodbye to Comcast just yet.
I just heard on a business show that Comcast is one of the BIG investors along with Google and Intel In the Clearwire - Sprint - WIMAX deal.

Also, I also put the WIMAX "antenna" on a metal shelf.
This is an old ham radio trick.
In place of a metal shelf a refrigerator will work nicely.
Don't forget to move it around and spin it for the best signal.

But it's such a drag, moving shelves and refrigerators around and spinning them.

Actually when WiMAX is first introduced in an area, it often does 11+mbps. Later on they start throttling users or the back-haul gets saturated. So if they wanted to, the technology can match Comcast. It is the implementation which sometimes limits it to the lower speeds.

As Davesworld mentioned the bandwidth isn't the issue for VOIP, this is just a comment on WiMAX.
