    I have the Mobile speed test app.
    I have recorded 30 Megabit download (3.5 megs per second)
    and about 1.1 megabit upload (0.12 megs per second)

    But i dont know how accurate the app is.

    Via the app bredbandskollen (the broadband test: http://www.bredbandskollen.se/) which is a website (and a smartphone app) based in Sweden, I get a download speed of 33.5 Mbit/s, and and upload speed of just above 9 Mbit/s on my iPhone 4.

    I have 100/10 (down/up) speed at home, which I almost always reach via this very reliable test site. At the time of testing the iPhone, I had 97.65 Mbit/s down, and 9.67 Mbit/s down on my computer.

    So using a 21mb high speed USB stick in my MacBook Air would give me considerably more speed than my iphone 4 or iPad 2?

    My results:

     

    iPhone 4S

    iOS 5.0.1

    Apple AirPort Extreme Base Station

    SPEEDTEST.NET App

    Las Vegas, NV Server

    Cox Communications

    20 Mbps / 2 Mbps

    25 Mbps / 2.5 Mbps (with PowerBoost)

    12/2/11

    9:13 PM

    47.45 Mbps / 7.86 Mbps

    64 ms

     

    I've come close to 50 Mbps / 10 Mbps with my iPhone 4S, but never with my old 3GS/4 iPhones.

    Here's mine:

     

    iPhone 4, IOS 5.0.1

    Asus RT-N16 running Tomato firmware, configured in "N Only" mode

    Comcast cable, San Francisco

    speedtest.net app

     

    On my wired PC, and on a laptop running Windows 7 with an 802.11n USB card, I get 34-36MB/s down & 6-7mb up.

     

    On the iPhone I get 15-16Mb/s down and about 6 up.

    The Tomato firmware on the RT-N16 indicates the laptop is connected at 150MB/s and the iPhone is at 45.

     

    Something's wrong with this picture... I'm still poking around to see what's up...  The "45" for the iPhone seems suspicious, as if it's connecting with 802.11G even though Tomato is configured for N-only.

    Which website(s) are you using for your speed tests?

     

    What speeds are you paying for?

  • 21. Re: iPhone 4 wifi speed?

    I test using speedtest.net and speedtest.comcast.net, and both report comparable results.  The speeds I indicated are actually the "burst" speeds, or as they call it, "Turbo Boost".  Sustained is 20mb I think, but the speed tests don't run long enough to validate that.

     

    The real point here is that the iPhone only gets half what the Win7 laptop gets even though both should be 802.11n.  I don't see a way to confirm that the iPhone is actually using 802.11n though, like I can on the laptop.

    What speeds are you paying for? It helps us to know what speeds your paying for.

     

    > I test using speedtest.net and speedtest.comcast.net, and both report comparable results.

     

    When your testing your speeds, are you using the same servers -- including your iPhone 4?

     

    Do you use the EZQoS (Easy Bandwidth Management)? On their website, it says you can "Allocate more bandwidth for your applications." Does that mean you can allocate more bandwidth for your iPhone 4. 

     

    > I don't see a way to confirm that the iPhone is actually using 802.11n though, like I can on the laptop.

     

    You should be able to.

     

    BTW: The iPhone 4S Wi-Fi speeds are a lot faster (from a home network) than the iPhone 4.

    Sorry, I may not have been clear in my previous response.  The rated (paid for, sold by the provider) sustained throughput is, I think, 20Mb.  The burst speeds are higher.

     

    But the issue here isn't whether I'm getting the throughput I purchased.  I am, without question, getting that throughput on both a wired desktop and on an 802.11n laptop.  However I get roughly half the throughput on the iPhone 4 that I do with either computer.

     

    So what I'm trying to determine is why the 802.11n iPhone provides roughly half the throughput as the 802.11 laptop (and why the 802.11 laptop has an indicated connetion speed of 150Mb and the iPhone is 45Mb.

     

    Oh, and to answer your question Doug, I am not using any QoS.  I think you're referring to EZQoS by Asus, but I'm not running Asus firmware, I'm running Tomato.  But, again, the throughput is exactly as expected with the laptop, but not with the iPhone .

    The answer is simple - the iPhone (like most phones) just isn't capable of the same speeds that a computer is.

    @bheiser1

    Could be that the iPhone4 wifi operates on the (802.11n) 2.4GHz.

    The "awesome" n speeds are achieved at 5Ghz.

     

    While the iPhone4 has the technical specifications (802.11n) it's not the full power 5GHz speed capabilities possible from the spec, possibly due to size constraints within an iPhone4.

     

    I'm not certain if the iPhone4S is the same or not but check Apples specs page 

    Hope that helps you out

    Hello,

     

    I bought yesterday a Wireless N router hoping to stream videos from my iphone 4s using Airplay to Apple TV 3rd generation faster than my Adsl2+ Thomson Gateway which is b/g.

     

    My new wireless router is: Tp-link

     

    I connected my Atv to Tp-link over wifi suggesting that ATV supports wireless N. And connected my Iphone 4s to stream a 2 min video this is about 300 MB size. And Streamed slowly and it played the movie after 30 seconds and buffered in the middle around 1 minute.

    I was disappointed and I don't know what is wrong with this whole network topology.

     

    The Tp-link wifi router is configured with:

     

    Channel: Auto

    Mode: 11n only

    Channel Width: Automatic (you can choose between 20mhz and 40mhz)

    Max Tx rate: 300Mbps

     

    **Note that there is no microwave or BT that is interfering.

    Any ideas please?

     

    Also note that I installed wifi analyzer on iphone 4s and it gave 54Mb/s wifi... The question what is the maximum Mbps does iphone 4s achieve on Wireless N routers 2.4Ghz? Is it 54? 150 , 300  or 450 ???

     

    Regards,

    (80 tests over a couple of year's time- wifi and 3g)

     

    WIFI

    Max download 18+ Mbps; Worst downloads around 2.5 Mbps

    Max upload is always exactly .93 Mbps

     

    3G

    Max download speeds 5.0 to 5.5 Mbps range; Worst dl speeds .16 to .25 Mbps range

    Max upload 1.06 to 1.08 Mbps range interestingly enough!
