Google Nexus cdma/lte Q's

[nmbs]

I was reading an article about how the Galaxy nexus will never be a vanilla Google experience phone on Verizon because Verizon offers a CDMA network and some such.

Anyways the thing I found interesting was the discussion about how the Verizon Gnex is not a truly LTE phone because it only uses LTE for data not for voice ( that would be through the cdma)

So is that why you have such bad battery life on the phone you have two chips connecting to two different networks all the time? What happens when you turn on WIFI?

I guess i just never thought about this and was wondering if anyone could elaborate on this.

Thanks

Verizon 4G phones have both 3G CDMA and 4G LTE rado chips. HTC phones are using qualcomm MDM9600 chip that contains both 3G CDMA and LTE radios. Others like Samsung, Motorola have two separate 3G and LTE chips.

It has 3G CDMA just in case it's out of 4G LTE area so that it can fall back to 3G data. But they never work simulataneously for data. Voice/text is through 2G 1X signal and this is always on regardless the phone is using 3G or 4G for data. Battery sucks faster just because LTE radio consumes more power.

I'm not sure that CDMA has anything to do with the Pure Google Experience (Vanilla). That's more to do with customizations of the system and enhancements implemented by carriers or OEMs (and mainly OEMs). Arguably Vzw forcing its two apps on the GNex could be counted as it then not being Pure Google, but then again, I see Pure Google as to whether it's customized or not, and the GNex won't be customized (since Sammy isn't putting TouchWiz in it).

I saw that article on PC Mag OP was referring to. To me it's completely gargage article. Pure Google experience has nothing to do with wireless radio technology. It's just that GSM is world standard oversea where wireless carriers don't have much saying on the phone and software.

I was really only interested in the lte and cdma radio stuff.

Well, it appears as tho you got your answer. Pure Google refers to the OS being unmodified by OEMs, not to the wireless technology used.
