Samsung recently revealed that it has created the world's fastest commercial Wi-Fi technology that can speed up downloads to 4.6 GB per second. 60 GHz (802.11ad) Wi-Fi technology, as it's called, can put 4.6Gbps or 575MB per second. FYI, we are presently limited to only 108mbps. Putting the calculation in simplest words, Samsung's Wi-Fi technology can download a 1GB file in less than 3 seconds and can stream HD uncompressed videos without any buffering. The type of routers we use right now beam internet at frequencies of about 2.4GHz and 5GHz having a range of between 50 and 200 feet. Samsung says that it would be putting the sci-fi technology to use in its gadgets as early as 2015.
To this question, there are two answers. The first is the speed that can be attained in the laboratories free of any obstacles. The second type of speed is the actual speed that the normal users will get, thanks to the damned obstacles in the course of the signals. So if the technology will be used in a free environment, the speed will go up to a baffling 5GBps per second. But in actual, the normal household speed can only touch up to 2.4 GBps.
The baffling speed this tech enables sounds very impressive on paper. But in reality, there are is one major problem with this sci-fi tech. The 60 GHz 802.11ad radio signals cannot penetrate walls, humans, doors or practically anything that comes in its way. And that is because 60GHz radio waves require line-of-sight. This problem, hence, limits the range of the router to just a few meters and the routers in use are placed in obstacles free environment, near to the point of use.
Samsung claims that it has overcome the problems faced by 60GHz technology. According to Samsung, it has developed "the world's first micro beam-forming control technology" and a "wide-coverage beam-forming antenna" that improves the 802.11ad device connection quality. But we strongly think that Samsung will take a long time to bring this tech to portable devices like smartphones and tablets and the invention is for now focused more on static devices like docking stations and wireless audio/visual devices.
