WiFi Performance

Microsoft made an unusual choice for Surface’s WiFi hardware, it uses a Marvell AVASTAR dual-band MIMO (2x2) 802.11n wireless network controller (88W8797?). Marvell tends to be one of the more cost effective players in the industry which could help explain Microsoft’s choice.

Despite the rarely used silicon, WiFi range on Surface is quite good. Subjectively I was able to hold on to 2.4GHz signals at greater distances than I could on both the 3rd gen iPad, ASUS’ Transformer Pad Infinity and even compared to the VivoTab RT based on some short time I had with the device. Surface also maintains good distances on 5GHz however the performance drop offs are far more significant.

The sweet spot for Surface’s WiFi appears to be around 40 feet away from an AP, with minimal obstructions (doors/walls are fine). Within this range in my testing I was able to maintain speeds of around 20 – 40Mbps. Add another 20 or so feet and you’ll see performance cut in half again.

Although range is good on Surface, at the outer edges of coverage you’re looking at 2 – 4Mbps, which is only really enough for casual web browsing.

The only real downside to Surface’s WiFi performance is its peak performance. I wasn’t able to get beyond 42Mbps when copying files to the device from a local server on the network. It’s possible that I was limited by some file sharing protocol overhead, but without a good suite of network performance tools for Windows RT it was the best I could do for now.

    With zero X86 apps compatibility Surface RT is just another tablet with keyboard running on outdated T3 with average/crappy display . All that for 600 bucks :(

    With full Microsoft Office and a keyboard that's a few millimeters thick, plus great xbox integration. Depends on what you prioritize.

    I’ve been following Anandtech pretty much since you started and this is the first time I’ve felt I needed to comment, and then actually made the time to leave a comment. First off thanks as always for an excellent review. I think the review is pretty clear that this product is intended to be Microsoft’s interpretation of a tablet class device. Everybody who’s complaining about a lack of features seems to want this to be a laptop or ultrabook replacement, which it clearly isn’t, and everybody who’s complaining about the screen seems to want it to be an iPad. To all the people complaining about journalistic bias, most of the criticisms you bring up are directly quoted from the article. Do you not see the clearly untenable position you are arguing from? If you possess the ability to read and understand what is written, it’s fairly obvious that the features, strengths and limitations of the Surface RT are all well written about.

    I hope I speak for the silent masses who don’t normally participate in the vacuous echo chambers that are web comments sections (I will admit that there are some very good commenter's on Anandtech though), whey I say thanks for the informed, intelligent, insightful and accurate reviews and news articles that make Anandtech the great site that it has been over the years.

    You spoke for me, that's for sure. Though I'm no stranger to commenting, most of the comments to this article are baffling/hateful. It's playing out like some weird black comedy and all I'm missing is the popcorn.

    I agree with your comment @A Geologist.

    If you look across the comments there are those who find the review biased towards Windows and want more issues to be reported. There are comments that find the review biased towards Apple.

    So it's become 'pick your bias and show your selected outrage.'

    I have always liked the reviews done on this site and regardless of what OS or device I use or prefer I enjoy reading features and charts and experiences and get a really good perspective of products.

    "The biggest issue I have with recommending Surface is that you know the next iteration of the device is likely going to be appreciably better, with faster/more efficient hardware and perhaps even a better chassis. "

    Then you might as well not buy an iPad or most certainly shouldn't have purchased an iPad 1

    The iPad 1 didn't offer a noticeably inferior user experience than it's closest rivals at launch thought, especially as it didn't have any:)

    It's a sleek device, but I really wonder if anybody can crack that market considering the huge barrier to entry that is the ecosystem. Apple is so well established in that space that Microsoft should have taken the Google route and try to get some space by pricing the device really low.

    On top of that, the Surface has a few issues :

    1. That screen looks nice, but the resolution is lacking. This is a geek erection shrinker and could reduce early adoption by us nerds
    2. There is some performance issues, even in the main UI. Hard to accept that when vanilla jellybean on the Nexus 7 and the iPad are always smooth (in the main interface at least)
    3. Lack of apps (that chicken and the egg thing)

    But I hope Microsoft can pull it off. I really like the UI and the push for more functionality on tablets.

    "1. That screen looks nice, but the resolution is lacking. This is a geek erection shrinker and could reduce early adoption by us nerds"

    I think most nerds would be looking at the surface pro as it is. Any higher resolution, and that Tegra would have a hard time. And a faster SoC would have driven the price up.

    I expected no less, great review! I am an exchange admin with my company, is there any way to review the functionality within a enterprise environment? At present we are forced to use a middle ware for "activesync security" can we expect any advancements with data security on the surface?
