Will BB10 support simultaneous Voice And Data?

**jhimmel** · 09-19-2012, 05:34 PM

Some iPhone fans I work with are pissed that the iPhone 5 will NOT support simultaneous Voice And Data On Verizon. Our phones are supplied by the small company that I work for. The plan is paid for by the company. The network is Verizon. We basically choose whatever phone we want. I have a BB 9850. Others have iPhones. At least one co-working was looking forward to an LTE iPhone on Verizon. He wants to drop his laptop Air Card from the plan, and tether to his iPhone instead. He was just waiting for an LTE iPhone for Simultaneous Voice and Data while tethered! Well, I guess he will have to wait for the iPhone 5s or something.

So, I assume it's too soon to know exactly what antenna's are in the BB10 handsets, and how they are provisioned for use, but I would love to know if the BB10 will support simultaneous Voice And Data on Verizon like all the Andriod LTE handsets already do.

Good question my man.

Doesn't this depend on the processor RIM use?

**johnenglish** · 09-19-2012, 06:14 PM

Yes it depends on the wireless chipset RIM selects for Verizon and Sprint phones.

There's not going to be a voice + data iPhone 5S for Sprint or Verizon. A third antenna would require Apple to produce a third model iPhone 5 which would cut into profit margins.

no it depends on the antenna the iPhone does nto have two antennas to support CDMA voice and data simultaniously where as GSM can integrate it all with one.

i think Apple released it this way in hopes that the CDMA upgrades will happen soon, and it might be since the problem with the iPhone is arising. if RIM decides to use multiple antennas they should be fine, we've yet to hear of any of the Android LTE devices having this problem on CDMA

**jhimmel** · 09-19-2012, 06:54 PM

Right, the Android LTE handsets on Sprint and Verizon do not have this problem because they equiped the units with the necesary antennas to do simultanious voice and data transmission. Apple chose not to, for whatever cost, battery, size, or whatever other unknown reason.

Waiting to see what RIM does with the new BB10 handsets designed for the same carrier configuration.

Three pages on the same question... No one knows the answer yet.

Knowing RIM, they would probably listen to what the carrier wants and that's probably a separate CDMA/1X and LTE chip for Verizon and Sprint.

Thanks for the link, nj! I just read through it. There is a lot of confusion and missinformation in that thread, and you are right - no conclusion re: BB10.

I believe when Verizon (or Sprint) launches Voice over LTE (voLTE) - this issue won't be a problem anymore. It will work just like any GSM/HSPA network.

The question is when is Verizon going to launch this for its LTE network. Hopefully sooner rather than later.

**jhimmel** · 09-19-2012, 07:37 PM

Yes, David, that is my understanding as well. I have not found any estimates on when that may be implemented. Those with Android LTE phones will not have to concern themselves with that. IPhone 5 users on Verizon and Sprint will just have to suffer while they wait. Us BB users will still just suffer while we wait for an LTE handset at all... Lol

CDMA does not support voice and data simultaneously TDMA does. LTE, 2G, 4G makes no difference. Sprint is CDMA and AT&T is TDMA. Code division tx/rx a dedicated data channel for handling the voice channel allocation. TDMA time division allows alternating time slots for handling voice and data.

CDMA alone can't do calls and data at the same time but Android handsets on cdma and lte(which is based on gsm technology) can do simultaneous calls and data, while they have lte signal.

I would be lost without this feature but I'm on gsm.

Exactly. It can be done, and is being done by pretty much all Android based LTE handsets on Verizon. The iPhone is actually the exception. I guess we won't know about BB10 until we have it.

**netviper** · 11-07-2012, 07:11 PM

I have it on pretty good authority that it will

**DarwinMejia** · 11-08-2012, 06:25 PM

4GLTE is NOT CDMA. 4GLTE phones use a sim card. so it is sorta like "TDMA"
so again its not a cdma issue, its more of a coverage issue. if you only have a "3G" signal im sure it'll be CDMA'ish and you cant talk and data, but if you have full LTE then i dont see why not... BUTTTTTT the radio RIM decides to throw on the phone will have the final say on said issue.

**manish408** · 03-03-2013, 02:03 AM

I am using the Blackberry Z10 in India with Idea network, when I am using the data than I am not getting any incoming calls. There is some problem in data and voice at the same time. Is any one have the solution.

**BBPandy** · 03-03-2013, 02:44 AM

I heard a while back that it would, but I forget where I heard it so I can't coment on the reliability of the source.

**simplayer** · 03-03-2013, 09:01 AM

Phones in the future will not support simultaneous radios. The only reason this was done was because there wasn't a way to do fallback to cdma while in LTE coverage. So their blunt solution was to just have both radios running at the same time. You don't want to do this because it's a tremendous battery drain.

Once IMS is up and running, you'll be able to do simultaneous voice and data on LTE.
