WiFi & GPS Performance

With the Transformer Prime ASUS moved to an all-aluminum construction but did little to focus on maintaining RF performance. The Transformer Pad 300 addressed WiFi and GPS performance by moving back to an all-plastic chassis, but as the high end in ASUS' Transformer stack aluminum was a necessity for the Infinity. The compromise is simple: a strip of similarly colored plastic across the top of the tablet, behind the WiFi and GPS antennas.

I performed a number of WiFi performance tests and am pleased to say that overall wireless performance appears to be much better than any previous Transformer tablet. I managed nearly 40Mbps in the best case scenario, but more importantly I was able to maintain 3 - 4x the transfer speeds of the TF Prime at further distances from the access point. I would say the Infinity's WiFi performance is now on par with that of the iPad, and is seemingly better at 2.4GHz.

WiFi Performance Comparison
Distance from AP 3 feet 20 feet (Different Room) 50 feet (Different Room/Floor) 80 feet (Different Room)
ASUS TF Prime (2.4GHz) 26.9 Mbps 9.85 Mbps 13.5 Mbps 2.20 Mbps
ASUS TF Pad 300 (2.4GHz) 26.5 Mbps 21.8 Mbps 20.7 Mbps 21.3 Mbps
ASUS TF Pad Infinity (2.4GHz) 39.2 Mbps 34.0 Mbps 34.3 Mbps 10.8 Mbps
ASUS Transformer (2.4GHz) 21.8 Mbps 17.6 Mbps 18.8 Mbps 15.0 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

ASUS still doesn't support 5GHz unfortunately with the Transformer Pad Infinity, so expect problems in situations with a bunch of 2.4GHz spectrum crowding.

GPS performance also benefits from the RF improvements to the Infinity. Although GPS locks are still not as consistently quick as I'd like them to be, the Infinity is generally able to get a signal lock quicker than even the Transformer Pad 300 - even in adverse conditions. While the Transformer Prime can't get a lock indoors or even in some situations in a car, the Infinity manages to do so in about 12 seconds. The shot below is what I saw after 12 seconds of searching for a lock:

To get something comparable from even the TF Pad 300 took well over a minute. I suspect the improvements to the Infinity go beyond simple chassis work based on its behavior.

    It will definitely be so much more. Rather than a smartphone OS on a tablet, it will be a bloated desktop OS on a tablet. Awesome!

    The truth is, people on both sides of this argument are making some valid points, but are having a lot of trouble listening and understanding the validity of contrary opinions.

    Only time will tell. There are things about Surface that look exciting, but there are lots of ways it can go horribly wrong.

    I'm actually quite interested in the surface pro. I want something that I can pretty easily carry around, since I don't like carrying heavy things. I also really want good pen input, since I would take notes on it, and as an EE student, a lot wouldn't be words, so pen input needs to be good. Finally, I love the fact that if I have any apps on it that just don't work with metro, I can always drop back to the desktop to use it, just in case.

    Plus the boot loader will be unlocked on the Asus vs. the Microsoft so you can install your own OS upgrades or even full desktop ARM-based Linux.

    Having come from an iPad to the TFP, I think Asus has a better looking, sleaker design than Apple. I know most people don't jump ship from ios to Android, but it's nice to see a product that kind of compete. However, like the ipad2/3 features, there's not quite enough to make me want to sell my TFP and upgrade. Keep it up Asus...

    Using hdmi on my bigscreen tv is awesome.

    My job gave me an iPad 3. When I got sick of it locking up on pages and stuttering, and the verizon 4g being enabled destroying my wifi speed when I left it on, and I got sick of pptp vpn connections dropping every 20 minutes, and I got sick of scrolling making it freeze solid for a few seconds, and I got sick of games like blooms td 4 completely locking it up... I'm really wondering how much they pay sites like this one to claim it's a great device. The lack of true multitasking alone. It's so annoying when network applications get frozen in the background and useless iOS tries to unfreeze them.

    I got the TF201. It's superior to the new ipad in every single way. Even facebook is better on it, and that's not supposed to happen. You can play temple run on both and watch the stuttering mess that is the ipad drop frames while the prime has no issues at all. And that's without talking about the stupidity of having no expansion slots, or the stupid 4:3 screen, or being so technically incompetent you have to exactly double your pixel count each time because you can't code scaling graphics into your design. Do you have to buy all new software for your computer when you buy a new monitor? You can't even download anything. All that and it's heavily and uglier also.

    The iPad is a toy with a broken OS on it. The Transformer line are actual desktop replacements. You can't even compare the two. You might as well compare guitar hero to a les paul.

    "'m really wondering how much they pay sites like this one to claim it's a great device."

    Dunno. How much are "they" paying you? It’s probably about the same.

    It's not that big of a deal really. You can spot bad review sites with biased reviewers pretty easily. trustedreviews is the only decent review site anymore. They just didn't have any information on the new king of tablets yet.

    I had a similar experience. My wife got an iPad 2 for her class in school for a semester and she absolutely hated it when compared to my old Motorola Xoom (yes, the original one).

    While iOS transition animations are always smooth, iPads are far from stable. On an Android tablet, while some of the UI transitions need work, you never get into a situation where the device freezes completely because the OS will force-close the app if it does. Apple wants to hide their imperfections from you, so iPad just takes a dump with no warning.

    Another thing that's annoying about the iPad is that for all the hype about the well-designed apps, iOS applications are very inconsistent. You don't know who nice it is to have a consistent location of the back button until you don't have one.

    I'm not saying that iPad sucks, far from it--it's a very nice device. All things considered, I can see that it could still be called the best tablet, though I prefer Android. On the desktop side, I actually prefer OSX for work, because it has a better command-line interface thanks to its BSD roots. I'm a programmer, so command line is more important for me. I'd probably prefer windows if I was doing graphics design for a living.

    This religious fervor about how "magical" the iPad is does make you wonder about Apple fanatics. It's not unique to Apple fans, but Apple fanaticism does seem to have a more cult-like feel.

    My point is--instead of trolling, try to make up your own damn mind.

    Heh, consistent 'location' of the back button, but not consistent behavior of it when you press it. ;)

    Both my iPad and Android phone have their CRASH and freeze moments. Both suck in different ways.
