iPad Wi-Fi + 3G: torn down


Bookending the iPad Wi-Fi + 3G unboxing from earlier today is the other classic staple of geekdom: the tear-down. As usual iFixit did the deed, and here's what they uncovered:

  • There are actually FIVE antennas in this iPad. Two antennas handle the cell reception -- one is in the RF window on top, the other attaches to the LCD frame. A single GPS antenna is also housed in the RF window on top. Just like the iPad Wi-Fi, there are two antennas that handle Wi-Fi / Bluetooth connectivity, one in the Apple logo and another to the left of the dock connector.

  • Apple looks to be using the entire LCD frame as an antenna!

  • Apple uses the same 3G baseband processor in both the iPhone 3GS and the iPad 3G.

  • The baseband processor in question is the Infineon 337S3754 PMB 8878 X-Gold IC. It was actually white-labeled on the production unit, but with enough sleuthing we were able to confirm its true identity.

  • The iPad 3G has a Broadcom BCM4750UBG Single-Chip AGPS Solution, whereas the iPhone 3GS uses an Infineon Hammerhead II package. Big win for Broadcom!

Head on over if you want to see the whole, sordid strip-down...

[iFixit, thanks Gregg for the tip!]

Limegrntaln says:

I'll make sure I stay away. I don't wanna get killed by an iPad. Why are people so into breaking these things?

Fixtnk says:

Why don't you drop one of those in my house.

Krypto74 says:

Tipb should start a charity drive. "got an ipad that you are dying to get rid of? Donate it to a less fortunate geek and eliminate the hassle of making a YouTube video that only 13 yearolds will find appealing for 2.5 minutes!"

Reshad says:

What a waste!! Nothing achieved here.

Orion2021 says:

I hate how people feel compelled to destroy an ipad for 5 seconds of fame. @J1CA1 glad you have so much extra cash lying around to buy ipads to destroy. How about you learn about helping others less fortunate and give one away to a person in need and perhaps contribute to society instead of destroy resources without cause.

Tweger01 says:

how about you mind your own business and stop worrying what other people do with their own money.
I'll never understand some people.

fassy says:

Any reports of the 3g iPad having the same (or similar) wifi problems that the wifi-only models have had?

Wow says:

@Tweger01 11:00am perhaps you should listen to your own counsel and not worry about orion2021's opinion.

anto says:

dun worry, they earn money much more to buy new one buy having this news.

Tweger01 says:

I was talking in reference to his concerns to other peoples money. Thanks for your concern though

BrianAnus says:

TK says:

That thing is mostly battery

Horton says:

Mine is having problems. It sometimes loses the connection or does not automatically connect. Went to the Apple Store and the guy had no idea what I was talking about. I didn't have patience to deal with it bc I was in a hurry. I'll check it out this weekend.

Horton says:

By the way... It's a 32 gb 3g

KP says:

I am just curious how big the battery is? Many people are bragging that ipad is such an energy saver than android tablets. Is it because of a bigger battery or the ios is better?
