iPhone Aloha Module Document

that confidentiality disclaimer at the bottom is not correct. the wording used on real apple documents is something completely different

Which is why this is a fake. Been there, done that in this thread.

Pretty good hoax if you ask me. The guy even added little Easter eggs for people to figure out.

If this is a design document it is VERY poorly done. It's nearly gibberish. By definition a design needs to show a set of parts and the relationship between them. This is at best just an uunorganized list of parts.

I've seen hundreds of software design docments. If I presented something like this at some meetng I'd be told generously "this needs work". I'd get allkinds of questions like "why a A next to B" what does hight of the chart mean? Dependency? In other word it it's a usless and meaningless chart.

Maybe this was found in Apple's dumpster our back of the building but I doubt that. Who ever wrote this is not a software designer.

But if I wanted to make you feel stupid, I would point out that microwaves are NOT radio waves any more than X rays are radio waves or infrared wavelengths are radio waves.

It's really just a matter if definitions. I would define microwaves as radio with a frequency above about 1Ghz.

In the US the FCC regulates use of the RF spectrum and the FCC does include 1Ghz and up as being in the "RF"

As it turns out the more technical the discusion the less liklely we are to see such ill-defined terms as "microwave" or "radio" and we simply see terms like "30cm band" that are actually meaningful.

My opinion is that "radio" refers to the way a transmitter and receiver are coupled. If they use antennas and are coupled by an electric field they are "radio"

If the devices are simply detecting total flux in band using something like the photoelectric effect then it is an IR system, (like the way a TV remote works).

Absolutely. And definitions vary from field to field. The IEEE terminates radio at about 1GHz, and in any case, the individual bands are all named and more clearly defined (for example, the S band containing nearly all cellular networks). This makes sense, given that engineers would rarely talk on a global scale about an entire section of the spectrum as broad as "infrared" or "radio".

In any case, the take-away point is that "radio" is simply the word for the modulator (or demodulator) hardware in the phone. It makes no reference to the point in the EM spectrum or to the method of transmitting music wirelessly (radio waves are simply part of the word's etymology, not its application). Radio is to cell phone as GPU is to video card.
