Droid Bionic Teardown Question [MDM6600??]

[shiva013]

hi everyone,

first time posting here..just wanted to ask a question on the bionic teardown that has been bugging me..

hopefully the experts here can shed some light?

ifixit's bionic teardown just came out..and for the life of me, i cannot understand WHY the bionic has an MDM6600...
i assume the bionic already has an MDM9600 for LTE, why in the world would they also have an MDM6600?? i havent heard of this phone being able to do simultaneous voice/data, maybe someone can shed some light on this?

As far as i know, the MDM9600 is suppose to LTE multimode, shouldn't that already cover everything the bionic would need?

maybe the mystery motorola chip is the LTE data chip? if Moto has any common sense they will use a version of this phone on other carriers and the MSM6600 will let them do it.

verizon's LTE network is data only. LTE advanced in a few years will do voice and data at the same time. maybe AT&T's implementation will do it this year?

maybe... i don't see any other big chips on the tear down, and i cant imagine where else they would hide an LTE chip.

I see what you mean about using this revision for other carriers, but that seems like it would be such a waste of space. Especially since qualcomm and i'm sure others will be making integrated lte multimode releases in hopefully the next 6 months. And unless these chips are footprint identical, the MSM6600 just seems..weak. It only goes up to HSPA 14.4 i thought.

Maybe the PM 8028 chip doesn't work with the MDM 9600 for power management, :hmm: or maybe the 9600 drew too much power so they stuck the PM 8028 chip on it? or maybe they had spare 8028 chips to use up.... :hmm:

Not entirely true.

In LTE all the operator has to do is provide different EPC bearers for voice and data. An yes, since they can be mapped to different channels, simultaneous is possible.
