802.11n – Wi-Fi’s next big thing

March 8, 2008 – 3:32 PM

A group of technology companies including Texas Instruments, Broadcom, and STMicroelectronics is pushing their proposal for the eventual 802.11n Wi-Fi standard that they claim will offer speeds “up to 10 times the speed of the current generation”. Glenn Fleishman over at Wi-Fi Networking News cuts to the chase: “An array of four receive and four transmit antennas in a MIMO configuration (4 x 4) would use 40 MHz of bandwidth, or about twice that used in current 802.11b and g, to achieve speeds up to 540 Mbps (raw throughput).” Of course as usual with Wi-Fi hardware, your mileage may vary.
