Wireless Performance: Cellular & WiFi

The Xoom ships by default with an EV-DO baseband for use on the Verizon network in the US. In practice I saw download speeds of anywhere from 0.35Mbps all the way up to 1.89Mbps and 0.10 to 1.09Mbps upstream. On average I got ~900Kbps down and ~600Kbps up, which is pretty typical for Verizon in North Raleigh.

By comparison the iPad 3G averaged 1.3Mbps down in the same locations as I tested the Xoom, but only 0.2Mbps up. Remember the iPad 3G has the same modem as the iPhone 3GS - it has HSDPA but not HSUPA so the theoretical max upload is only 384Kbps.

Motorola and Verizon will be offering a free upgrade to an LTE modem later this year. The modem will have to be physically soldered onto the motherboard so it’s not an end-user upgrade. There’s already an LTE SIM slot and tray built into the Xoom for use post-upgrade.

The Xoom also features an integrated 2.4GHz 802.11n WiFi radio supporting a single spatial stream at up to 72Mbps. In practice I measured a peak transfer rate of 36Mbps, which makes the Xoom the fastest device we’ve ever tested over WiFi (the original iPad was the previous king at 30Mbps).

WiFi Performance

Like all other Android 2.2 or later devices, you can create a personal hotspot with the Xoom and share your cellular data connection with other devices over WiFi.

    The platform is not that old. Apple just took their existing ois from the itouch and made it bigger. This is a whole new ballgame. Early adopters should understand their will be some hiccups...

    Glad to hear the WIFI only version is coming out March 27th for 599.00 This brings the competition directly to ipad and ipad2. My boss offered to buy me the ipad2 and I told him I only want an ADAM or a Xoom. An ipad would be a waste of money....I need a business tablet. Not one whose product is so proprietary...that you can't even load an app unless its through their store....how controlling is that?

    Samsung changed some of the basic internals of the system (I believe mainly to do with the filesystem and location of certain files). This makes it harder on them to release updates and also causes compatibility problems with certain applications.

    For me, I would only stick to the high end HTC and Motorola phones - they have the proven track record of updates. If you really want the latest and greatest for some reason, then you will want the Nexus line of phones.

    Not entirely true. Most custom froyo roms were based on galaxy s from overseas. Look at captivate, AT&T's froyo update just came out and the same phone offered through canadian carrier had froyo for quite some time now

    "Android however did it the simplest way possible: tap home and run what you want to run next." Pre-Honeycomb Android has press-and-hold on the Home button which brings up a list of recently-used apps and can be used to switch between running tasks. Has had this since the first release I think.

    Woops, you're right :) That's very much a precursor to what Google did in Honeycomb, and tap-and-hold home is now out.

    Updated!

    Take care,

    It's not a true tablet, but the NOOKcolor is a nice device for the money. If you are willing to do a little dirty work (mainly writing to a microsd card and booting it - very easy), you get a very basic tablet with a very nice screen for $250.

    I imagine for most users who use their tablet for web browsing, facebook, twitter, and youtube, that's plenty and a great bargain.

    I guarantee there will be a usable version of Honeycomb running on it within six weeks. There is already a functional version, although with a decided lack of applications and very unoptimized.

    I can't imagine anyone else competing with a wifi only tablet. My guess is that there are two reasons to avoid releasing such: First, you can overcharge and let the consumer pay the subsidy (and then some) back to the carrier. Second: nobody tries to compare it to the nook.

    I read so many of those tech blogs that sometimes I forget what a real review looks like. Good work.

    Some of those benchmark results are pretty odd.

    I wonder if the disparity between the Optimus 2X and the Xoom might in some way be related to the dual-core support in Honeycomb? The optimus is running on 2.2 which I understand has limited (if any) support for multiple cores.

    Maybe the benchmark apps are showing some measure of incompatibility with the new code? Just a wild guess.

    Just once I'd like to read a review of any piece of mobile tech where the reviewer stuck to reviewing the hardware in his/her hands instead of constantly comparing it to an Apple product. For Christs sake, enough is enough already! And don't give me that "Apple Set The Bar" BS. I'm not buying what you're selling! I've owned 3 generations of iPhones, an iMac, and 2 MacBooks so I'm very familiar with Apple products and I have great respect for them. But the simple fact of the matter is that not everyone wants to live the iOS/OS X lifestyle and when they read a review of non Apple products I'm quite sure they don't want to see Apple brought up every other sentence.
  • Enormously Hatworthy - Thursday, February 24, 2011 - link

    It is annoying but whether we like iOS/iPad or not (and I don't, to be honest) it is the market leader in tablets right now. It's the frame of reference for buyers.

    I think they'd be doing their readers a disservice if they didn't make the comparison.

    Notice that in laptop/desktop reviews you'll see scarcely a mention of Apple products (unless they're talking about size and weight).
