Simultaneous voice and data?

[TMFGO45]

I know you can do it when you are on 4G, but what about when falling back onto 3G when outside a 4G area?

I dont think it does. But at the same time, i hope not. Someone recently stated that this was one of the reasons the thunderbolt had such poor battery life. Ive never had it, so i dont think ill miss it.

Don't you also get voice and Data when connected to WiFi as well?

Yes you do, but the question was referring to 3G when Wifi or 4G are not available. Im on wifi all the time as well (Home, Work) and have 4g luckily in my area. So i never notice not having it.

I thought it worked over 3G too...could be wrong but I thought the TB supported the latest rev of CDMA which included simultaneous voice and data.

This is not latest version of cdma. Verizon never changed that. What HTC does is use the MDM9600 chipset in the Thunderbolt and Rezound. What this means to end users is simul voice and data on either 3G or LTE. This is done by moving all data to one radio, and voice to a separate one.

Viola! You have a hardware trick giving simultaneous data and voice.

Samsung, LG, and Motorola do not use this trick. Instead they have voice and 3G on one radio, and LTE on another.

Thats how they do it, without ever upgrading cdma. I doubt Verizon is interested in upgrading cdma when it will be phased out before long.

This is frustrating coming from a thunderbolt. I only have 3g where I live and I've gotten used to it. Are there any solutions other than going with a rezound?

So, the Nexus can do simultaneous voice and data as long as you are on 4G then?

Correct.

Install Google Voice, set it up for dialing on the GN, all voice will go out the 3G or 4G network without using minutes, your DATA can also concurrently function as well. Tested multiple times and confirmed online billing that minutes are not being used.

 

[JDMDATL]

Better check it again.

ALL Google Voice calls on ALL mobile phones (Android, iOS) consume your plan's voice minutes.

GV on a computer (using the Call Phone link inGmail) uses VoIP and a data network connection.

GV on a phone, regardless of hardware or OS, does not work on IP. 100% voice network only.

Was a follow up to the post immediately before mine:

Just to break this down if someone didn't understand, this trick is called Fusion, and it doesn't have to be MDM9600, any LTE->EVDO chipset can do it.
HTC Thunderbolt and Rezound use a separate chip for voice and 1X and secondary for 3G/4G, That drains crap load of battery, but it works.
Everyone else uses one radio for 1X, Voice and EVDO, and the secondary for LTE only.
Reason? Only a few companies have licenses from Qualcomm to produce CDMA basebands.

I also believe it needs to be set up on a tower by tower basis, as some of the technology is not capable of providing this without an update.

 

[twindragons187]

all 4g devices do voice/data on 4g. like previous poster stated, thunderbolt actually use's 2 1X radios, 1 3g radio and 1 4g radio.

its its radio setup is like 1X/3G, 1X/4G.....thats how its possible. the gnex doesn't use this. the gnex is 1X/3G, 4G.....

I believe this to be wrong.

If I recall correctly, right now all VZW is using 4G LTE for is high speed data. They do not use it for voice calls.

When you are in a 4G area, the hi speed data is handled by the LTE network. Voice calls, 3G data, 1X data, & text messaging is handled via the CDMA network. A 4G LTE radio cannot handle CDMA 1X or 3G data; its not possible due to being on entirely different radio frequencies. If it could, there would be no reason to have dual radios in these devices and we would all be much happier with battery life.

TBolt, if I recall has a dual CDMA radio and 1 LTE radio. Thus, it allows simultaneous voice and data on both 3G and 4G dependent on network availability. When on 3G, on radio handles the voice, and the other handles the data.

Negative. Thunderbolt has a CDMA radio, and a MDM9600 3G/4G radio. Voice over 1x is always on, and MDM9600 handles the data, hence simultaneous voice/3G voice/4G.
