iPhone 5 vs. iPhone 4S: 5GHz 802.11n vs. 2.4GHz 802.11n Wi-Fi Speed Test [Video]

We've posted a Wi-Fi speed test comparing the iPhone 5 on 802.11n (5GHz) versus the iPhone 4S on 802.11n (2.4GHz).

The video below shows the transfer of three files (10MB, 50MB, and 100MB) from a local wired server over Wi-Fi.

The iPhone 5 with its 5Ghz 802.11n support clearly blows away the iPhone 4S by transferring at over double the speed. If you previously tried iTunes Wi-Fi sync but thought it was too slow, you might want to give it another try.

The 2.4GHz band is far more congested and thus prone to interference resulting in slower speeds. While the 5GHz band is less congested and can offer faster throughput, its disadvantage is shorter range and difficulty penetrating solid objects.

Take a look at the video below...

Regardless if anyone is using the iphone 4 or 4s, the iphone 5 is a signfiicant enough improvement that it warrants upgrading, whether or not your free upgrade is available from your carrier. If it isn't you could try selling your old phone for around $356.56 http://www.movaluate.com/apple/iphone-4s-16gb-att-black According to Movaluate's fair price appraisal, you should be able to easily sell your phone for that much, which could help pay for the $750~ y ou will need for teh iphone 5 off contract.

is this just because the 2.4GHz radio is using a 20MHz channel and the 5 GHz radio is using a 40MHz channel.

You are comparing different things. Surely the speeds you get on 4s are 2.4 g band. 5GHz is less congested, speed is dependent on hardware since packets you sent from your phones are generated on them, routers might be different for each test, so on and so forth. 5GHz is not a good choice for indoor use and you won't find it in other public areas because its not that good for covering this sort of devices in that way. If you have problems in your house try a good n router or a combination of APs in your house. For as little as 200$-300$ you can get a full set of 3 APs all packed with software controlling them. dlink Ubiquiti and others have sets like that. Good luck
