Apple’s Antenna Design and Test Labs

After getting called out for having an issue every cell phone has, Apple did a photo shoot of a testing facility that every other cell phone manufacturer also has and used it as marketing.

I think we've found the problem. The guy in the chair is only testing the phone with his right hand.

They certainly don't kid around when they finally decide to answer bad PR.

John Cage visits an anechoic chamber: 'Cage entered the chamber expecting to hear silence, but as he wrote later, he "heard two sounds, one high and one low. When I described them to the engineer in charge, he informed me that the high one was my nervous system in operation, the low one my blood in circulation." Cage had gone to a place where he expected there to be no sound, and yet sound was nevertheless discernible. He stated "until I die there will be sounds. And they will continue following my death. One need not fear about the future of music."' - <a href="http://goo.gl/mFI5" rel="nofollow">http://goo.gl/mFI5</a>

The one thing they never talked about is the difference between the iPhone 4's external antenna (exposed) and the internal antennas in most phones.<p>Testing a various websites shows that while most phones drop signal, the iPhone 4's signal dropped significantly more because the antenna is exposed and your skin comes in direct contact with the antenna rather than just in close proximity.<p>With the bumper "fixing" the problem, wouldn't putting the antenna inside the case essentially create the same fix by putting non-conductive material between the user and the antenna?

I like how the $100M testing labs include a rubber band and some sticks to hold the phone.

Fascinating. To my non-radio-engineer eyes the patterns look like acoustic dampers—is it an illusion that they resemble the foam wall inserts in a recording studio, and these are actually composed of a different material to affect megahertz radio waves?<p>Furthermore, how are they <i>supposed</i> to affect those waves, and to what end?

This looks like something out of a James Bond movie villian's hideout - all it needs is a self-destruct sequence announced over the PA system by some lackey with a monotone voice who inexplicably sits through the entire process while paitiently waiting to be engulfed in flames by the resulting explosion.<p>Sorry, I've had a lot of caffeine today.

100% high-tech except for the rubber bands to hold the phones to stuff.<p>Edit: point being that sometimes simple things are the best inventions.

I found the base antenna site (<a href="http://www.apple.com/antenna/" rel="nofollow">http://www.apple.com/antenna/</a>) pretty enlightening.

So, from a scientific point of view, the conclusion is: their model of the real world is wrong.<p>It wouldn't suprise me, I've never seen so many blue spikes in one place ;)
tzsalmost 15 years ago
How rigid and tough are those spikes? If you fell off the walkway while walking out to the test platform in the first picture, would it likely cause serious injury to you, or would it just crush a bunch of spikes and get you in trouble with your boss?

I have an HTC Hero and it also drops quite a few calls, but somehow I've just learned to live with it.

Better title: "Apple's insanely cool PR response"
mattdawsonalmost 15 years ago
My first reaction when I saw these pictures was "Holy crap! Apple went and built a danger room![1]"<p>I can't be the only person who had this thought.<p>[1] <a href="http://en.wikipedia.org/wiki/Danger_Room" rel="nofollow">http://en.wikipedia.org/wiki/Danger_Room</a>

I was in one of the cell network provider's testing lab a few times. They also do things like RF testing before putting the device on sale, but their lab doesn't look any similar to that. They have a bunch of Faraday cages (think of labs with sheet metal walls) and lots of RF emulation equipment - phone's getting connected through the RF port on the back; RF emulators take care of simulating any bad RF conditions that you could possibly imagine. So, their labs don't look that fancy at all. Still they manage to have devices that could be held any way you want.
pinchyfingersalmost 15 years ago
I don't see how this helps their situation. This just adds weight to the idea that they willfully ignored the problem and shipped the phone with full knowledge of the antenna problems.

Does anyone know what material is used in making those cone-like pokey things? My immediate guess would be that its some form of dense foam to damp waves; but what exactly are they?

Before clicking the link I was about to post a pedantic "please change to a headline that doesn't editorialize", but after a second of looking at the pictures...holy crap! That is (objectively) insanely cool! :)

Feature: Antenna tested in state of the art lab Benefit: The antenna works
JustinSeriouslyalmost 15 years ago
That is an alien-looking world.<p>It gets more exciting if you mute it and put on Liberi Fatali in the background.
Emorealmost 15 years ago
I bet you the money in my pocket that this lab was <i>not</i> called "Antenna design and test lab" prior to the press conference; part of the brilliance in this deflection of attention is most certainly found it the naming itself of this awesome place.

Do the people with this problem have different physiological properties in their hands? Such as more conductivity..<p>No matter how I hold any of my iPhones, reported signal strength is the same.<p>Anyone else experiencing this?
bprateralmost 15 years ago
How can they make such a massive investment in this type of thing and end up with such a big 'oops'? It must be heartbreaking for the antenna engineers.

Why can't they leave the Blackberry and all the other mobile phones out of the game?

You think that they could use something other than rubber bands to hold the phones!

Seeing a giant 10-story, foam-padded test facility doesn't exactly seem like real world use to me, but then again I know nothing about proper cell phone testing procedures.

Too bad they tested iPhone 4 while wearing their rubber lab gloves.

No "wall of PR", my ass.

why didn't they just test it out in public...where it would normally be used.

The fact that Apple is giving free cases (<a href="http://www.engadget.com/2010/07/16/apple-to-give-away-free-bumpers-to-iphone-4-users/" rel="nofollow">http://www.engadget.com/2010/07/16/apple-to-give-away-free-b...</a>) means that the iPhone antenna has a bad design.<p>So they spent million of $ to improve the antenna and forgot this little detail? Where are the testers?

Wait... what? The fact that they thoroughly tested it and <i>still</i> had as big a problem as they did is supposed to make us think they're more competent?

Well, whatever the critics say about apple,their products are very reliable unlike other.

Wow...that is so impressive (not) I have seen tons of these anechoic chambers used by antenna manufacturers...Apple and their amazing marketing gimmics...

This lab looks really cool....but the timing of this page being seeded makes me believe its little more than a PR stunt! :) kudos apple fr givin us the iphone 3g/3gs/4...but the antennae problem was just too embarrassing for u guys!

This was a triumph. I'm making a note here: HUGE SUCCESS. It's hard to overstate my satisfaction. Apple Computer We do what we must because we can.

This is so silly. There's a feynman quote where he was talking about how at MIT they had this really fancy test facility, but it never produced any results, because the people running the tests were in another room an never saw anything happen.<p>Then at Princeton, where they were in the same room, the machine (which was much less fancy) produced much more information because people saw what was going on as it was running.<p>Seems to me that this could easily be something of the case. Fancy test facility with no grounding in anything.<p>Furthermore isn't it kinda more embarrassing when, instead of admitting there was a problem, they just say that the phone was tested. It seems to imply that the issue is intentional.
