A little education for your Saturday with a nice article from WirelessWeek.com titled ‘What They Don’t Tell You About 802.11n’.
As it stands, the most common WiFi standard amongst mobile phones is 802.11b with some handset owners lucky to find 802.11g (the ‘b’ standard being much slower than ‘g’ for those who want to know the chief difference). 802.11n is supposed to be another 10 times faster than 802.11g while up to 50 times faster than 802.11b.
While b and g operate on the 2.4ghz frequency, 802.11n operates across 2.4ghz and 5ghz.
In January 2004 IEEE announced that it had formed a new 802.11 Task Group (TGn) to develop a new amendment to the 802.11 standard for wireless local-area networks. The real data throughput is estimated to reach a theoretical 540 Mbit/s (which may require an even higher raw data rate at the physical layer), and should be up to 50 times faster than 802.11b, and well over 10 times faster than 802.11a or 802.11g.
So, theoretically then, something that is 50 times faster than what you might be using (like going from dialup internet connections to broadband connections) should solve or reduce any issures with wireless video or media transmissions. Then again, it might not.
