I was "gifted". Worst curse you could wish on someone.

 

That's somewhat misleading.

 

The "EVO Family" has sold 7 million.

 

EVO Family includes:

 

EVO 4G

EVO Shift 4G

EVO 3D

EVO View 4G Tablet

EVO Design 4G

That may be as my memory sucks.

I will look for the article. It was something about this being a followup to the Evo 4G, "of which 7 million were sold.

But I think you are probably right as Sprint has what, 50 million subs? I doubt 7 mil, or 14%, got the Evo 4G.

Have you tried any other DNS Servers such as OpenDNS?

Yes.

Can using other DNS Servers like OpenDNS show significant changes to service?

You bet. I prefer Google's DNS servers of 8.8.8.8 and 8.8.4.4. I doubt where Sprint's servers are would make much of a difference but I would bet that they would be slower and more problematic then Google's.

There was a big East Coast outage where a specific model of card could not get to any webpage unless you used its IP address. Sprint took a couple of weeks to find and fix that so I just changed people to Google.

Sprint maintains two redundant data centers though I cannot remember where they were. I suspect the DNS servers would be there. Why?

Just read an article that said Sprint sold 7,000,000 Evo 4Gs.

 

Holy moly!

 

I got my evo 4g off contract and it came out to 478 inc tax

That is what is showing as retail price before discounts/rebates/credits.

Off contract price is $549.

From FierceWireless

T-Mobile USA and Leap Wireless (NASDAQ:LEAP) agreed to swap AWS spectrum in several markets across the country to boost capacity, which Leap said will help it improve its LTE capacity as it deploys the technology.

 

 

Click here for details on T-Mobile refarming plan.

The deals also involve Leap's noncontrolled, majority-owned venture, Savary Island Wireless, as well as T-Mobile's joint venture with Cook Inlet. Financial terms of the deals were not disclosed. The FCC will need to approve the swaps.

 

Under the swap, Leap will get 10 MHz of additional AWS spectrum in Phoenix, and Houston, Galveston and Bryan-College Station, Texas. Leap and Savary will give T-Mobile spectrum in various markets in Alabama, Illinois, Missouri, Minnesota and Wisconsin. The transactions also include intra-market exchanges among Leap, T-Mobile and Cook Inlet in Philadelphia, Wilmington, Atlantic City and various markets in Texas and New Mexico, and between Leap and Cook Inlet in certain markets in Texas.

Sprint has their own DNS servers.

 

Was it 15 LTE phones' date=' or 15 LTE devices? I might be wrong, but I thought it was devices. So that would probably give us somewhere int the neighborhood of 8 or 9 phones this year. (since there will probably be a 2 or 3 tablet, 2 hotspots, and a usb dongle).[/quote']

 

Correct. Devices. Including broadband cards and mobile hotspots.

Has anyone ever seen a Cricket' date=' Cellular South, MetroPCS, or U.S. Cellular antenna on a tower?[/quote']

 

I thought most if not all if those just used one of the major carriers.

No joke. I actually want to learn even more (and be able to understand what is being posted.)

I am trying to learn more about the wireless technology for which I provide tech support. Anyone have links to material that an intelligent layman could understand. Somewhere around undergraduate level.

Yes. If the polarity can be reversed.

I suspected Sprint was upgrading cell towers but i've had no way to confirm. Is there any way to confirm without special equipment?

Yeah. Check Robert's maps or I can look at work.

Look at North Florida on the map' date=' and you can see what I have to deal with.[/quote']

 

I reviewed all their reports before making my decision to jump to big red. I was on Sprint 10 years' date=' so carrier moves are something I don't take lightly. I'm a little upset that Verizon didn't win 1st place in Dallas, but that is the one market they don't have cellular 850 in-- only PCS A block there... but at least they won every other market.[/quote']

 

And these posts are relevant how?

I suspect either hand off issues or the overlap/underlap is problematic. Wireless dorks, what say you?

Here are some more stats for Chicago market:

Capacity upgrades:

91 to 180 days ago = 298

Last 90 days = 59

Next 90 days = 382

91 to 180 days = 498

Seems like a strategy change in there or something. They slowed waaay down and are now screaming.

 

Chicago is a spectrum constrained market. Yes.

Found some info.

"High block/drop rates: During the migration to Network Vision those customers on the boundary between NV sites and legacy sites will experience a higher than normal block/drop rate. The rate will continue until the boundaries are reduced by the introduction of additional NV sites."

I think you're right. It only seems to be in markets where 3G NV sites have gone live and not in the markets where only 4G LTE has gone live. They are rapidly firing up on Chicago. And the I-110 corridor in LA too. Sounds like NV 3G deployment is the culprit. I will keep my eyes open to see if I come across specifics about what is at play.

Illinois was one of the areas with horrible capacity issues, wasn't it? Maybe Sprint is cutting over 3G towers as they go to alleviate the issue and will go live with 4G LTE later.

I have confirmed it is the NV conversion that is causing major headaches from Chicago west. I suspect we will see lots more issues as other towns convert.

However, I suspect it will be just the 3G NV radios that cause the issues now. I know they have lit up 4G NV towers here with no 3G NV radios and we have no problems. I can check Chicago tomorrow again, but I do believe they are firing up 3G towers.

Robert, can you confirm?

I will start recommending to customers.

At home with marginal coverage.

Interesting thing is that there was very little fluctuation between tests unlike Speedtest.
