You're kidding, right? That CANT be the first time you've ever heard that wifi is 50 times faster than your internet speed.... Because it's been like that for the past 10 years, from B to G to N now.
Theoretically.
I've yet to encounter a network that didn't seem noticeably more sluggish on the wireless side than the wired computers on the same LAN.
802.11b was/is especially poor... I know it *can* do 11Mbps, but it never really does.
G is much better, but still far from perfect.
Also, don't exaggerate. 50 times faster? Really? A typical broadband connection in the US is somewhere around 6Mbps. 802.11G is 54Mbps peak.
That's 9-10x more bandwidth at 802.11G's maximum bandwidth. A far cry from "50x".
Let's not even delve into latency on wireless vs wired networks...
Wireless has a LONG way to go before it'll be able to top a wired connection, even for web browsing. It's very good, but to a discerning user such as myself, it's an obvious difference.
Now for my rant on this 3g nonsense...
I live in Portland, ME and 3g was rolled out here last November. For the first few months, it was relatively speedy and I was quite pleased. It has quickly degraded, and the 3g service is now not only slow, but also so spotty that I leave EDGE on most the time, preferring a reliable connection to quickly check my email rather than crossing my fingers that the 3g will actually establish a connection, give me an IP and let me download what I want within a reasonable timeframe.
I'm not sure where they will be managing to deploy 7Mbps 3g with any reliability... I think AT&T is a little in over their heads.
