@@@ Those face-meltingly fast new 802.11ac routers might not be king of the wireless networking world for long. On Sunday, Samsung announced it鈥檚 developing new 802.11ad Wi-Fi technology that can turbocharge network speeds fivefold, from today鈥檚 866Mbps per-device maximum to a blistering 4.6Gbps. At that rate, Samsung says, a 1GB movie file can transfer from one device to another in under 3 seconds. The secret sauce: Ditching the crowded 2.4GHz and 5GHz wireless channels used by today鈥檚 routers and jumping to the 60GHz frequency band. Even though you might not have heard of them, neither nor the idea of are new. But prior implementations have run into a brick wall, both literally and figuratively: 60GHz signals can鈥檛 easily penetrate walls. That鈥檚 obviously a big problem for real-world usage. Most of the 60GHz-capable "WiGig" accessories are designed to operate at very, very short ranges as a result. But Kim Chang Yong, head of Samsung鈥檚 DMC R D Center, says the company has 鈥渟uccessfully overcome the barriers to the commercialization of 60GHz millimeter-wave band Wi-Fi technology.鈥?

Samsung鈥檚 says聽it overcame those physical and metaphorical barriers with "high-performance modem technologies and by developing wide-coverage beam-forming antenna." The WirelessHD and WiGig standards groups have also been trying to improve 60GHz signal performance using , a Wi-Fi technology that detects where client devices (like PCs and tablets) are physically located and then sends a focused signal directly at those devices, rather than mindlessly broadcasting a Wi-Fi signal in all directions as most routers do. (Beam-forming is already becoming a common feature in high-end 802.11ac routers.) For the future, not today Don鈥檛 start saving your pennies for this particular bit of next-gen networking kit just quite yet, however. While Samsung鈥檚 press release states that 鈥渃ommercialization is expected as early as next year,鈥?that鈥檚 only talking about industry-wide usage of the 60GHz frequency itself鈥攏ot necessarily the release of Samsung products packing the company鈥檚 new technology. A Samsung spokesperson provided the following statement to John Ribeiro of the IDG News Service: "As 60GHz is an unlicensed band spectrum globally, along with 2.4GHz and 5GHz spectrum, industry-level of commercialization is expected as early as next year, but there's nothing we could confirm at this point on when Samsung products supporting 60GHz Wi-Fi will be available in the market." It seems 802.11ac routers will have to do for now. Fortunately, there are a聽聽聽聽 .

The story behind the story: The idea of making wireless networks as fast or faster than wired connections holds obvious appeal鈥攖he less time you spend waiting for files to transfer, the more stuff you can get done. But while Wi-Fi improvements like Samsung鈥檚 new technology should (eventually) turbocharge sharing files, streaming locally stored movies, or across your home network, don鈥檛 forget that a fast router won鈥檛 magically make your actual Internet connection any faster. Activities like browsing the web or zoning out on the couch and watching Netflix are usually limited by your Internet speed, not your router.
