A Faster Wi-Fi World Is Coming

A FASTER WI-FI WORLD IS COMING
[SOURCE: New York Times, AUTHOR: David Pogue]
“When I was your age,” we'll someday tell our awe-struck grandchildren, “wireless Internet was available only in isolated hot spots 100 feet across!” That is, if everything works out the way the electronics industry hopes. Every couple of years, it rolls out another flavor of faster, better Wi-Fi equipment, bearing such uninspired names as 802.11b and 802.11g. This year’s edition is 802.11n, which is supposed to offer two huge advantages over the popular “b” and “g” types: 5 times the speed and 15 times the range. That would be a big deal, if it were true. It would mean, for example, that the signal from just one transmitter — one wireless router, to use the technical term — could fill every room in your house with glorious waves of data. It turns out that “n” does offer better speed and range — nowhere near 15 times better, but generally at least 2 times. One “n” router should be enough to fill even a McMansion.
