iPad mini Review
by Anand Lal Shimpi & Vivek Gowri on November 20, 2012 6:10 PM ESTWiFi Performance
The mini uses the same Broadcom BCM4334 WiFi controller as the iPhone 5. The WiFi stack supports dual-band 802.11n as well as fallback to 802.11b/g.

Since the mini uses the same WiFi stack as the iPhone 5, you get support for 40MHz channels on 5GHz networks (20MHz on 2.4GHz). The maximum PHY rate supported is 72Mbps on 2.4GHz and a whopping 150Mbps on 5GHz.
In terms of actual performance, this works out to be a maximum of just under 100Mbps on a 5GHz network with 40MHz channels. In practice I wasn't able to get higher than 91Mbps, although Brian managed a very nice 95.7Mbps on the iPhone 5 in his tests. On average I pulled nearly 78Mbps on the mini on a 5GHz network. Move down to 2.4GHz and performance is cut roughly in half (peak performance is around 41Mbps).
I didn't have any issues with WiFi reception or performance in my testing of the iPad mini. The only complaint I really have at this point is I would love to see more intelligence when it comes to switching between multiple known APs of varying signal strengths. This is a problem on pretty much all devices I play with, they tend to want to stay on an existing network even if its performance drops significantly and there is another, better performing network that could be jumped to. I feel like some more intelligence in this department (testing nearby networks, looking for an ability to seamlessly switch and get better performance) would help mitigate a lot of the inevitable "hey my WiFi is broken" complaints we often see with a move to a new WiFi stack. You could also argue that we just need better designed WiFi deployments.

Am I the only person who thinks Anand is just another Apple shill who just falls over himself supporting any and every Apple product out there? Please. What ever happened to the objectivity that once was the hallmark of Anandtech? I've watched the same thing happen to Tom's Hardware over the years. I guess it must be the koolaid they drink.uhuznaa - Wednesday, November 21, 2012 - link
Well, maybe this *is* objective and what you want to read is something subjective that starts and ends with "everything Apple is crap"?This review points out all the weak points of the device, comes with a lot of objective numbers and benchmarks -- what do you miss exactly?

I really don't think it's necessary to make personal insults against the staff. Yes anand clearly likes apple. But look around. So does half the continent.edsib1 - Wednesday, November 21, 2012 - link
You state that the mini display is great but, in your own tests...Pixel density - 5th of 7
brightness -13th of 17
contrast - 17th of 17
calibration - 6th of 7
grayscrale - 3rd of 7
saturation - 4th of 7
GMB - 6th of 7
I dont understand your conclusion. Doesnt add up to a great display to me.

The answer is two-fold.FIrst, the tests were against other rather good screens. So coming in "average" is actually quite good. Here's the key statement, near the end of the review, "It pains me to say it, but compared to most similarly priced notebooks, the iPad mini's display is amazing."
Second, often times the margin of difference must not have seemed significant to Anand. For example, if two screens are 1% apart on a particular metric (pulling a number from nowhere) then which came in 1st vs 2nd is a relatively meaningless.

i personally dont get it. i have an ipod touch, iphone and ipad and pretty much never use the ipod or ipad. the ipad is only good for checking an email quickly or looking at a youtube video. anything beyond that and its frustrating to use. personally i would rather have a laptop/ultrabook. not sure i understand making the mini other than just to have a cheaper "i" product to complete with kindles and androids. i didnt think apple was about going cheap.Jumangi - Wednesday, November 21, 2012 - link
I can't see how any tech enthusiast site could look at the Mini and be impressed at the overall product. A 1 1/2 year old SoC. A screen resolution that goes back even farther and skimping out at 512MB or RAM. Any other manufacturer tried to pull that off would get slammed on all points but because the Mini has a nice case well all is good I guess...drx11 - Sunday, November 25, 2012 - link

You can not see it, because it is in the software... the SoC the apps, etc... you miss the forest for the trees. You miss the computer (system or tablet) for the specifications of the various parts...

Hi Anand thanks for the article.I was wondering if you had any plans to review the new B&N Nook HD 7" tablet? It would be interesting to read your findings on it's higher resolution screen. Also any plans for a tablet round up pre-xmas, as they are a nice size/price for potential presents? It seems the choice comes down to Nexus 7 vs N&B Nook/Kindle fire HD or the mini Ipad for iOS.

"I don’t consider the iPad mini a competitor to the Nexus 7"What the heck? I jsut do not understand the continuous worshipping of this company's garbage products. It is almost like people dont even actually use these things. In reality, ther eis no difference between this and something like a nexus 7. They're both going to be extremely limited, extremely frustrating devices. iPoopa are anything but buttery smooth flawlessly running devices these biased reviewers make them out to be. I can make my iPoop crash just by opening webpages. Every time I'm scrolling thru the app store it lage like hell. The thing is really unbearably slow in jsut about everything. I only have about 100 apps installed. (58 of which want to update right now, but hell if I'm gonna bother.) I hate this thing. I only use it as a remote control nowadays. Even that crashes. It's really terrible. I refuse to believe that it is something unique to my device. What's more liekly to me is that the people who never have any problems with these things are the people who never actually use them.
