1.4Gbps? I'd love to get 1.4 Gigabits per second.
Keep in mind that 1.4 gigabits per second is actually 0.175 gigabytes per second (i.e. 175 megabytes per second) since there are 8 bits in a byte. 175 megabytes per second is the highest bandwidth available on the iPhone and it would be the download speed if the entire intracellular network was directed to one iPhone alone. But divide 175 megabytes per second among thousands of intracellular networks in the ATT coverage area and you'll understand why 1.4 gigabits per second is not that fast. When you reduce the maximum bandwidth in the pipeline it slows everyone up, much like a clogged drain.Last edited by mdude85; 02-03-09 at 02:51 PM.

By your logic, the entire 3G network is sharing 1.4Gb/s (.1879 GB/s). So (again, by your division logic), if there are 2,000,000 people sharing 187.9 MB/s, each phone will get about 94 bytes per second.
Yeah, I guess they really DO have reason to complain.02-03-09 03:36 PM - It doesn't really work that way since 2 million people would not share .175 GB/sec equally. By using the word "divide" I insinuated that the bandwidth was divided but not necessarily divided equally among all the users in the band. It's not really too big of an issue because the actual bandwidth is never as high as advertized or measured. Basically the issue comes in only for enterprise users since a lot of companies have to decide whether to outfit their employees with laptop (air) cards or with iPhones. Since the iPhone restricts bandwidth compared to air cards then it might not be the best choice, especially for high bandwidth scenarios like secure/class (classified) RDP. Not that you would use an iPhone for a class RDP anyway since the class networks like some in the US government don't typically support iPhones for enterprise. The article is just making the point that users are experiencing poor download speeds on the iPhone and its restriction on max bandwidth draw from the network may be a contributing factor. I'm not so sure how much of a role it really plays but it's worth mentioning I think.I agree.

02-03-09 03:46 PM - Well, I was correct that 1.4 gigabits per second is 8 times higher than 1.4 gigabytes per second. Merely because the article made a typo does not mean that I am somewhat incorrect. Perhaps you mean to say that the article is somewhat incorrect.You're (mostly) correct, but your math went downhill when you didn't realize that it was just a typo in the article.
I think regardless of typos, it would be interesting to see how the maximum bandwidth restriction on the iPhone, if there is one, affects WiFi rather than 3G, especially since 3G will be phased out soon.02-03-09 03:54 PM - Your math was decent. I should have specified - you were somewhat incorrect, because you also stated:Perhaps that kind of bandwidth is available on the iPhone via USB, but it's certainly not coming over the AT&T (or any) 3G network.02-03-09 04:10 PM
