New IEEE 802.11ac Specification Approved Due to the Need for Higher, Multi-User Throughput in Wireless LANs

IEEE has approved the IEEE 802.11acTM-20131 specification to achieve higher multi-user throughput in wireless local area networks (WLANs).  This new revision intends to improve WLAN user experience more than 10 times the speed compared to the previous version, with data rates up to 7 Gbps in the 5 GHz band.

The revised specification adds channel bandwidths of 80 MHz and 160 MHz with both contiguous and non-contiguous 160 MHz channels for flexible channel assignment. By adding higher order modulation in the form of 256 quadrature amplitude modulation (QAM), users will experience an increase of 33% improvement in data rate.
