You might not have to wait until 802.11ad arrives in earnest to get a big boost in WiFi network speeds. The Wi-Fi Alliance has officially debuted the 802.11ac wave 2 standard, which promises a big leap in speed without reinventing the wheel. It doubles the bandwidth per channel, which could double your performance in good conditions. You're more likely to hit those speeds, too. There's an additional spatial stream and wider 5GHz channel support, and MU-MIMO (multi-user, multiple input multiple output) lets routers send data to multiple devices at the same time -- you're less likely to see your download bog down because someone else in your home is streaming video.
