October 14 - 4:10pm EDT   California electronics newcomer Quantenna today said it has developed chipsets that it believes should end the problem of adequate Wi-Fi coverage in most homes. The QHS450, QHS600 and QHS1000 all use a unique four-by-four MIMO (Multiple In, Multiple Out) antenna setup that not only reduces the amount of interference that often crops up in walls and other wireless devices but theoretically allows much more bandwidth than regular Wi-Fi. Where current technology hits 300Mbps in peak conditions, a network blanketed with the QHS1000 chip could top out at 600Mbps in data transfers, Quantenna claims. [full story]
