The Apple iPad Review (2012)
by Vivek Gowri & Anand Lal Shimpi on March 28, 2012 3:14 PM ESTWiFi & GPS
The WiFi stack gets an update with the new iPad courtesy of Broadcom's 65nm BCM4330, compared to the BCM4329 used in the previous two iPads. Both 2.4GHz and 5GHz operation are supported, although as I mentioned earlier the carrier-dependent personal hotspot is only available over 2.4GHz.
As with most smartphone/tablet designs the BCM4330 only supports a single spatial stream, for a maximum link speed of 72Mbps. Similar to the iPad 2, Apple hides the WiFi antenna behind the speaker grille at the bottom of the tablet. The cellular antennas (there are now two) are at the top of the tablet, behind the plastic RF window.
| WiFi Performance Comparison | ||||||
| Distance from AP | 3 feet | 20 feet (Different Room) | 50 feet (Different Room/Floor) | 100 feet (Different Room) | ||
| ASUS TF Prime (2.4GHz) | 26.9 Mbps | 9.85 Mbps | 13.5 Mbps | 2.20 Mbps | ||
| Apple iPad 2 (2.4GHz) | 35.1 Mbps | 29.9 Mbps | 26.9 Mbps | 10.6 Mbps | ||
| Apple iPad 3 (2.4GHz) | 35.1 Mbps | 29.9 Mbps | 27.9 Mbps | 9.98 Mbps | ||
| Apple iPad 2 (5GHz) | 36.7 Mbps | 36.7 Mbps | 36.7 Mbps | 11.9 Mbps | ||
| Apple iPad 3 (5GHz) | 36.7 Mbps | 36.7 Mbps | 36.7 Mbps | 11.7 Mbps | ||
With a similar WiFi stack and similar antenna placement, it's no surprise that I noticed very similar WiFi performance to the iPad 2.
The same goes for GPS performance between the new iPad and the iPad 2. Both devices were able to lock and track me driving around in a car with comparable accuracy from what I could tell.
Airplay Support with the new Apple TV
When paired with a second or third generation Apple TV, the iPad supports wireless display mirroring or content streaming to the iPad via AirPlay. In other words, if you have an Apple TV hooked up to your HDTV, you can use your HDTV as a large, mirrored, secondary display for your iPad—wirelessly. The only requirement is that you have a 2nd or 3rd generation Apple TV and that it's on the same network as your iPad. With those requirements met, enabling AirPlay mirroring is simple—just bring up the iOS task switcher, swipe left to right until you see the brightness/playback controls and tap the AirPlay icon.
Mirroring gives you exactly what you'd expect—a complete mirror of everything you see on the local iPad screen. All sounds are also sent over and come out via your TV's speakers—the local speaker remains silent.
The frame rate isn't as high on the remote display, but there's virtually no impact to the performance of the iPad itself. There's noticeable latency of course since the display output is transcoded as a video, sent over WiFi to the Apple TV, decoded and displayed on your TV via HDMI. I measured the AirPlay latency at ms, which is reasonable for browsing the web but too high for any real-time games. If you want to use the iPad to drive your HDTV for gaming you'll need to buy the optional HDMI output dongle.
While AirPlay mirroring on the iPad works at 720p, if you're playing a 1080p movie on the new iPad and you have a 3rd generation Apple TV, the video is also displayed in 1080p rather than downscaled to 720p.
Video playback is an interesting use case for AirPlay and the iPad. If you don't have mirroring enabled, you can actually start playing a movie on the iPad, have it stream to your TV via the Apple TV, and go about using your iPad as if nothing else was happening. Most apps will allow you to stream video in the background without interrupting, however some games (e.g. GTA 3, Infinity Blade 2) and some apps (e.g. iMovie) will insist on streaming their UI to your Apple TV instead.
Although iOS and the iPad don't do a great job of promoting multi-user experiences, using AirPlay to push video to a TV wirelessly is an exception. If you frequently load your iPad up with movies you can use it to keep others entertained while you either get work done or just goof around on your iPad at the same time. It's a great fit for families where people want to do two different things. If you do put a lot of movies on your iPhone/iPad, the 3rd generation Apple TV is probably a must buy for this reason alone.

It's a shame some people argue that against the workers when over a hundred of them have committed suicide over the working conditions. How can you still say that they are being offers a better deal here??On the other hand, it is also unfair that Apple is being singled out here. The world of Chinese manufacturing is a dirty one and all major corporations have a part in it. I'd trust Apple over most other companies to make a difference in that regard, and I'm happy to see something is being done in that regard. Ever heard McDonalds CEO touring the slaughterhouse of the meat packing companies??

Reporting suicides as a number not as a rate shows you to be either a fool or a deliberate liar. How many people, over how many years, comprise the pool from which this suicide number is drawn? Everything I have read says that the actual suicide rate is not only lower than the average rate for China, it is lower than the average rate for the US.mr_ripley - Friday, March 30, 2012 - link
In 2010, 18 workers attempted sucide, 14 succeeded. To me even one in a whole year is not acceptable. If you think that is ok I hope that statistic turns out to be you!!name99 - Saturday, March 31, 2012 - link
The argument was NOT that suicide is a tragedy, it was a claim that FoxConn employees specifically tied to Apple production have such lousy lives that they commit suicide in higher numbers that other people around the world.You have done NOTHING to prove this claim; all you have done is bring up a very different issue.

There is no disputing the fact that these deths are related to working conditions. I'm pretty sure this has been well established and documented. However, I did say in my previous post that Apple is unfairly singled out. It could have been any other company.Comparison between suicide rates is irrelevant. Higher sucide rates elsewhere does not justify this problem. Again the fact remains that many people have died and it is directly related to the working conditions.
Apple happens to be in a position to directly influence their lives and make it better, after all they profit in billions from the work these people do. Corporations typically place little value over human life and living conditions (IBM sold equipment to the Nazis to track the Jews in concentration camps). Somehow, I feel Apple is different.

Dude, sorry but you're talking no sense at all.First of all, pretty much any product you want to buy, electronics wise, uses parts from China where conditions are far worse on average, than Apples factories. So if you actually factored working conditions into the product review, it would look favourable for Apple.
Secondly, your argument that comparison between suicide rates is irrelevant, is absurd. Higher suicide rates where legislation is such that no jobs suffer such terrible conditions that suicide is the only option, such as is the case here, prove that even if working conditions are refined, you still get some depressed people. Your argument, therefore, is with the people who committed suicide. You say it is 'directly related to the working conditions' but where have you evidenced this, at all? You simply haven't. The fact that the suicide rates at Apple factories are lower than some American ones further backs up my point on this.
Every company is in a position to change lives and make them better. You too, are in a position to do this. But guess what. You, just like companies, can do WHATEVER YOU LIKE with your OWN MONEY and have NO OBLIGATION WHATSOEVER to solve the worlds problems. Apple already has amongst the best conditions of factories in China. The amount of profit they make is absolutely irrelevant, if you say Apple should be putting money into this then a lot more manufacturers should also put a lot more money into this. It's very easy to decide what other people 'should' do with their money now, isn't it?
Corporations don't have to adhere to moral values - they are not people. They are there solely to make money. Nothing else. Don't confuse them with people. And I hope you donate every single spare penny to charity and spend every spare second of your time working to build homes in the 3rd world. Oh wait, you're on here crying that other people should do it instead.
Get a hold of yourself you illogical fool.

Like I have said before it is a shame some people argue with great zeal against others who are suffering and devalue human life. Fortunately, Tim Cook is not one of them.If scores of people killing themselves citing poor working conditions is not enough proof what is? If your claim that there are work environments in America that have higher suicide rates because of working conditions is true that needs to be investigated as well and rectified.
You give charity to people who are in need and cannot earn for themselves. If you think giving someone fair amount of compensation for hard work is charity you are delusional.
If working in those factories is such a pleasent experience I suggest you try it out for yourself. Maybe the experience might broaden your perspective.
Although, I don't see the point I will attempt to educate you. Legally, a corporation is considered as a person, that is right just like a live human being. Regardless of that corporations are run by people and actions of a corporation reflect upon the morality of the people running them.
I will stop here as there is no point in continuing but you can respond with more insults and accusations of what I do or have done which frankly is no concern of yours.

I've not seen a single report of people killing themselves and citing "poor working conditions" as the reason. Can you provide a link?There have been reports of people killed because of unsafe working conditions, but that's a different issue. Maybe you're confusing the two.

Here's a Wikipedia link: you can read some of the circumstances and judge for yourself.They may not have said it in so many words but it is clear they were unhappy with ther work environment.
Imagine your boss coming and beating you up because you lost an iPhone prototype!!!
