Modification of IPhone5
Modification of IPhone5
(OP)
Dear friends
Now I'm doing a project to add the third RF path to Iphone5, for it can't accomplish the task of SVDO (simultaneous voice and EVDO). This is a big problem for subscribers using Verizon and Sprint's network.
You may know the orientation of antennas on Iphone, to describe it clearly, please check the picture below.
The problem is reverse engineering, for apple adopt a new lightning connector with TI BQ2025 chip for security purpose ensuring reliable and high quality (licensed) peripherals. The worse case for me is only abtaining some power for lightning connector, Do you think there is any posibilit to reuse the RF chip inside Iphone to provide a single additional antenna.
As an alternative solution, how about setup this third RF path by the headset jack? Yes, I can provide more pictures to show the internal structures and Chip infomations.
Another question is if I can't reuse the internal RF chips, I'll setup a external link with it's WIFI antenna. That is to say I'll build a TX/TR for CDMA data only, and redirect signal to WIFI antenna by addional TX/RX. There maybe some EMC consideration, How do you think?
This device maybe build by Flexible electronics and attached at the backside metal area of Iphone

RE: Modification of IPhone5
Seriously, this so-called project is preposterous.
RE: Modification of IPhone5
Yes, I was on the first stage of giving the feasibility of this project. Although I know part of the story, I still want to make sure there is nothing omitted.

It's also on Verizon's store.
