Re: Wireless G vs Wireless N You are right. I misspoke.
11n can get to QAM64 and thus higher than 11g's 54Mbps. But the signal to noise ratio needed for this is such that the range is short enough, or so few walls can be in the path, that it, to me, is not common.
Of course, these bit rates are merely the 802.11 burst rates. The net yield at the IP layer is more like 60% of the burst rate.
Most 11g systems, at 54Mbps, can yield 24-26Mbps net, and there are few IP service providers offering that rate, and moreover, how many Internet hosts will provide that per client connection?
So these higher WiFi speeds are useful for huge file transfers between PCs within your own LAN. Or streaming HD. I stream standard def. TV (MPEG2, 6Mbps) just fine with 11g and have for years.
So 11n, esp. when the Standard is ratified, and we have lower prices and true interoperability, begins to make sense, in terms of cost-benefit. Today, IMO, it's a novelty for the geeks among us. |
