And
@bsweetness, I have seen you say several times one antenna, and I don't doubt you. Still, I thought it was one less radio (not antenna). I'll have to go back and read again.
In the case of the Turbo, it has multiple radios: LTE, CDMA, and GSM/WCDMA. But it only has one antenna that's shared between those radios. This is confirmed in the
FCC documents, most notably
this report. Here's an image from the report that shows a layout of the antennas in the phone that shows only one WWAN (cellular) antenna:
By contrast, if you look at the
FCC documents for the Droid Ultra and MAXX (specifically
this report), it shows two separate cellular antennas, one for LTE and one for CDMA/GSM/WCDMA:
Also, if we want to look at another phone using the same Snapdragon 805 processor that the Turbo has (which means the exact same radio setup, although some bands may not be active on one or the other), here are
the FCC documents for the Sprint Galaxy Note Edge (I couldn't find the documents for the Verizon Note 4 or Note Edge, so another CDMA carrier will likely have the same setup).
This report shows multiple cellular antennas that allow for the use of the CDMA and LTE radios simultaneously:
I have the Verizon Note 4 which has the same Snapdragon 805 processor that the Turbo has, and I can confirm that simultaneous voice and data over CDMA and LTE does indeed work. It has exactly the same radios as the Turbo, but it has an additional antenna that makes the simultaneous usage of CDMA and LTE possible.
I hope that helps to explain why I keep talking about the Turbo only having one antenna.
