Re: iPhone competition makes all the carriers better...

VoLTE isn't looking too promising yet. Current attempts drain the battery 50% faster than CDMA. Apple just needs to put in the same CDMA radio as Android phones, which allow voice/data even on 3G.

When VoLTE rolls out heavily they will magically have to remove the unlimited talk and put a minute cap once more upon it..

Watch and see if i'm wrong

They'll just prioritize Voice on the LTE network and keep it unlimited. It's using the same amount of data on the LTE network as it would be on the legacy 3G and 2G networks. And with the freed up spectrum from users moving voice traffic from legacy networks to 4G networks the carriers will be able to allocate more spectrum to LTE. Voice traffic will use a very small amount of deployed LTE capacity on cellular networks in the US as mobile traffic is rapidly switching over to mobile data use and text messaging.

I suspect unlimited talk will be the norm because there will be no minutes to use. Your talk time will be converted to data...mark my word.

I doubt it.. It will be touted as high definition voice service! But with a time cap

We will see.. I was right about the caps on internet usages for lte and even landlines that most was ignoring because "they had theirs".. But not everyones being effected and everyones at a hiss over it..

Personally, 3g speeds would work for me just fine if it was on a better frequency.. Voice as well.. My verizon Iphone drops way more than my trak phone (backup) running through the att network... Not to mention a much cheaper made phone.. Frequency makes a difference in places..

Its not a CDMA radio it is missing but an LTE chip that allows data to flow through LTE and voice to travel over CDMA at the same time. Rumor is Samsung owns a lot of those patents for that LTE technology and Apple didn't want to pay for it.

The LTE chip doesn't control it. The phone has to have enough antennas for both LTE and CDMA to transmit and receive at the same time.

SVDO requires two CDMA radios, one for Data and one for Voice, each of which require their own antennas AFAIK.

Verizon isn't doing SVDO. Verizon abandoned developing phones on CDMA that will do SVDO. Instead they have worked with providers like Samsung to make LTE chips that work with CDMA for voice while the data is coming in on the other side of the coin. The only 4G phone that can do SVDO right now is the HTC thunderbolt, every other 4G phone that can do voice and data at the same time use a specialized LTE chip that enables that functionality. How do I know this because I work in the wireless industry and my company provides the crap to make it work.

HAH okay.

Qualcomm makes the silicon that makes the connection to the tower. SVDO is done either with VoLTE or a combination of LTE and GSM or LTE and CDMA. When out of LTE coverage you need two radios for CDMA to support SVDO. Any Verizon phone with 3G SVDO capabilities will have two radios for CDMA regardless.

Please stop talking out of your ass.
