I'm sure this is old news by now, but I just figured out that the E4GLTE is capable of using data while on a call. I was sitting here:

 

 

14160 Trinity Blvd

Fort Worth, TX 76155

at a Wendy's, on a call, and got an email notification.

 

I did a speed test and got this:

Which is way faster than I ever get with Sprint's 3G.

It is if you're connected to LTE, this was 3G Data + Voice.

 

That's what I was asking about. So I guess E4GLTE is the only phone so far capable of voice and 3g data.

But somehow I read here

http://insidesprintnow.wordpress.com/2012/05/25/svd-simultaneous-voice-data-on-lte-phones/

that all Sprint LTE phones are capable.

Hmmm, that's a good one, I guess we'll see. I know a few folks here have the Galaxy Nexus and they can't do SVD

I think the LG Viper 4G LTE is the only other phone that I can confirm works SVDO. And of course or lovely EVO LTE's! Whoot, as this is one of my favorite features!

In addition doesn't the tower have to have NV completed to do that? Which would suggest the far greater than average 3G speed.

 

Don't think it has to be a NV tower. That's the HD voice thing.

Reports are that the LG Viper can also do SVDO.

 

I have a Viper and can confirm that it does SVDO. It's great too!

Damn it. I just tried and it didn't work. Will have to wait for LTE.

 

Which phone do you have?

Looks like a G-Nex' date=' based on the profile.[/quote']

 

Thanks. I'm not at my computer to look right now.

SVDO capability is a side effect of other design requirements for the phones. The LG Viper LTE and EVO 4G LTE both require a dual-SOC design to achieve LTE capability and as such have dual antenna. As I understand it, this allows for two separate CDMA signals to be broadcast/received from the device simultaneously, thereby achieving SVDO.

 

It is not an advertised feature and probably never will be on these models.

 

SVDO only works in good coverage areas, and is not guaranteed anywhere, even with theoretically perfect coverage. Voice will always take priority over data when spectrum or signal strength is an issue.

No, that is no longer accurate.

 

The Viper and previous VZW handsets that support SVDO can do so because they utilize dual Qualcomm modems, typically one MSM paired with one MDM. Typically, the MDM chipset is used for LTE connectivity; however, since the MDM is also EV-DO capable, it opens up SVDO capability.

 

With the arrival of the Qualcomm MSM8960 (and other S4 chipsets), on the other hand, the EVO 4G LTE utilizes a single chipset that supports CDMA1X, EV-DO, and LTE, plus SVDO or SVLTE.

And I have been corrected. Haha.

 

As I said, wasn't completely sure, but that's how I understood it. I understood obviously the capabilities would change over time, just never though phone releases just a month or so apart would be the time frame it would be for Dual-SOC requirements to go away.

Will the GNEX3 support SVDO?

 

Have you read our article on FCC authorization of the Galaxy S3?

      Definite usage quirks in hunting down these sites with a rainbow sim in a s24 ultra. Fell into a hole yesterday so sent off to T-Mobile purgatory. Try my various techniques. No Dish. Get within binocular range of former Sprint colocation and can see Dish equipment. Try to manually set network and everybody but no Dish is listed.  Airplane mode, restart, turn on and off sim, still no Dish. Pull upto 200ft from site straight on with antenna.  Still no Dish. Get to manual network hunting again on phone, power off phone for two minutes. Finally see Dish in manual network selection and choose it. Great signal as expected. I still think the 15 minute rule might work but lack patience. (With Sprint years ago, while roaming on AT&T, the phone would check for Sprint about every fifteen minutes. So at highway speed you could get to about the third Sprint site before roaming would end). Using both cellmapper and signalcheck.net maps to hunt down these sites. Cellmapper response is almost immediate these days (was taking weeks many months ago).  Their idea of where a site can be is often many miles apart. Of course not the same dataset. Also different ideas as how to label a site, but sector details can match with enough data (mimo makes this hard with its many sectors). Dish was using county spacing in a flat suburban area, but is now denser in a hilly richer suburban area.  Likely density of customers makes no difference as a poorer urban area with likely more Dish customers still has country spacing of sites.

      Mike if you need more Dish data, I have been hunting down sites in western Columbus.  So far just n70 and n71 reporting although I CA all three.

      Good catch! I meant 115932/119932. Edited my original post I've noticed the same thing lately and have just assumed that they're skipping it now because they're finally able to deploy mmWave small cells.
