What would be the effect of metel on compass and nfc wifi 5ghz etc ?
just asking as say your body replacement goes like "wow i want that thing " then a bit of hypothetical neo900 mods wont hurt if applicable as i believe a lot of your customers do care about that

Magnetic sensor... Not sure how it can be handled. Estel?
Best wishes.
Substances that are negligibly affected by magnetic fields are known as non-magnetic substances. They include copper, aluminium, gases, and plastic. Pure oxygen exhibits magnetic properties when cooled to a liquid state.

NFC would be one more antenna to put outside the metal-body (via external connector), along with WiFi-Bluetooth and Cellular and FM.

As I had understood it, Estel was planning on adding radial antennas internally to the full body replacement, for the existing stock antennas. It may be possible to do that same thing with any additional antennas? I have only the most primitive understanding of antennas (e.g. I know the formulas for basic electromagnetism and stuff, nothing really practical for modern antennas), but from what I thought I understood from Estel's explanations in this thread and others, that would make signal travel fairly well despite the aluminum body replacements?
But, in our application of whole body replacement, it doesn't matter - for the radios, we have a thousands orders of magnitude bigger "problem" with the *conductor* used for body (that is, Alu). Incidentally, conductor act as shield, in this case - even on it's own, but even better when it's grounded (at the very end to battery - not real ground, but still). It is the case for N900's metal parts (border around screen, back of screen...), and will+must be the case for body replacement.
Due to this, in full body replacement, antennas will get "re-delegated" to the outer side. Think N950's antennas, just without N950's poor radio performance (as they have failed with the quasi-coil antennas).
Of course, there is still the port for connecting external antenna for N900 that is a crucial (read: must have) part of body replacement which will allow to get absolutely superior radios performance in special situations - but I'm absolutely sure that performance of internal antennas is no less important, for everyday use. Won't neglect that part, that is for sure.
Side note - I was *very* tempted to create complete new internal fractal antenna, that could get integrated into back part of body replacement. But, designing one that will work well is hell of a task, with much, MUCH testing and trial&error (even if using antenna designing software, like 4nec), so it would delay body replacement part considerably (it could take as long as doing everything else...). So, it's idea that I'll try someday for my own, slowly, and report if I succeed

Quite off topic but I'm wondering why this thread has "gangnam_style" tag?
