New Version of Wi-Fi

WSJ.com - Personal Technology

MIMO -- which stands for Multiple Input, Multiple Output -- is likely to be the basis for the next major flavor of Wi-Fi, now under development, which goes by the technical name 802.11n. It's intended to replace the most common flavors used in homes today, which engineers call 802.11b and 802.11g. But MIMO is so good that makers are rushing it into the market even before the new standard is complete.
