NTT DoCoMo's never been one to back down from the future, and some might say this carrier is actually already living in 2012. You know -- Land of the Rising Sun and all. At any rate, its latest foray into what's next came at the Wireless Technology Park in Yokohama, where it demonstrated a fully-functional 802.11ac prototype wireless system. For those unaware, that's what is scheduled to make 802.11n look like the 101 at lunchtime, with an effective throughput of 1Gbps per system. If all goes well, NTT will be commercializing the system "within a few years," and based on a demonstrated throughout of 120Mbps (as in, real-world results), we're hoping "few" becomes "one."
