    Since we can't send/receive large files over WiFi, can someone tell me the advantage of using n on an iPhone?

    Well, now I don’t have to have two parallel networks….

    Exactly ... No phone could even saturate 802.11g ... let alone laptops. The fastest wireless I've seen at my house on comcast cable internet with my time capsule 802.11n is maybe 7-8mb/s

    There is no point. It's for the marketing guys. Its one of those useless functions that looks nice and shiny on the spec sheet.

    Its not all about speed, most peoples internet doesn't even top out 54 Mb which is g's limit, and you wont be transfer files either on it much, the biggest benifit is range.

    Everything will eventually move to Wireless-N just like it did from B to G. It's just new Wireless Technology.

    I think the biggest reasons are that wireless n has a further range and people who have n only networks don't have to run dual channel.

    I think range is better, but also I remember reader a while back that 802.11.n chipsets are also able to user some newer power-saving techniques, in an effort to decrease their toll on the batter.

    I have noticed a substantial increase in speed with my iPhone 4 over my 3G.
    Before i would get around 4-6mb/s and now i am getting between 10-13 mb/s
    No more waiting to buffer and quick loading of internet pages in Safari.
    Just well peeved that i suffer from the 3G reception loss, dropping from 2.9mb/s to around 35kb/s truely awfull :(

    It would be useful, but it's running in the 2.4 gig spectrum like g does so it really doesn't help me.

    Isn't there some deal that if you have a network with only 'n' devices it works better than a network with mixed devices on it?

    If so, it's nice to not have a single cell phone drag down performance for all your other devices. (I don't know if this is true, but it feels like something I've read before...anyone know for sure?)

    802.11n range is worse at the same level of power output. unfortunately, they beefed up the power output of 802.11n so that it goes further (only just).

    the point of 802.11n is for connection to the 802.11n networks - but it must be noted that the iPhone 4th gen CANNOT connect to 5GHz networks, only 2.4GHz 802.11n networks (or is it the other way round lol). unlucky.

    barefeats have tested the new iphone upload and download speed -

    3g download: 1827kbps
    4g download: 2986kbps
    = 63.4% increase

    3g upload: 179kbps
    4g upload: 1656kbps
    = 823.6% increase.

    i think that is the reason for the upgrade ;)

    Yes, but the problem is it's 2.4Ghz, not the 5Ghz everyone has in their home. So it's compatible with really nothing. That is why it's useless.

    Yeah I did notice this. I use my Wireless-N and G on different bands and I had to update my 2.4 to mixed mode. I will probably just let the phone run on G. Won't make much of a difference really.

    Another FAIL.

    I wonder what is next?

    Exploding iPhones?

    Even close to my AE (Dual Band) it's maxing out a 39mb/s rate, which is more than adequate for the iPhone. I assume there's some rational for the "N" capability around security, etc. Also I have heard some networks configured N only (though it would make sense for those networks to be 5ghz N only... so there goes that theory).

    For comparison, I stream 1080P MKVs over the network to my LG Bluray, the outbound stream from my Mac is only ~10mb/s..

    The iPhone 4 is first, the other two are an Airport Express and my MBP.

    Yeah, I'm keeping my iPhone 4 on my separated G airport network too.

    I don't see N really benefitting me on the iPhone much, however there is an app that I occasionally use over my local network that streams iSight video from my MacBook or iMac, in this case the N might come in handy, however, it's always worked just fine over G so I won't worry about it.

    How is it compatible with nothing? My wireless router has both 2.4GHz and 5GHz radios in it. Dual-band routers aren't uncommon, and at this point, aren't even all that much more expensive either.

    Early adpaters of N though did not get Dual-Band. He was just saying a lot of people are probably not on Dual-Band Routers.

    I've always had issues with my Wireless-G devices on a band that shared N as well. Dual-Band fixes that issue well. Maybe a simple Software update will fix the Single Band issue on the iPhone.

    The point is that if you connect to a N network it will not drop to G. So if you have a N network at home and use your phone on it then everything else continues to run N.

    I find I have much better range with 802.11n on my iPhone.

    It supports running on n networks. But at the reduced frequency, meaning your entire network suffers if don't have dual band.
