Creating and Optimizing 802.11ac Signals and Measurements

Show Description

The new IEEE 802.11ac wireless LAN standard, currently under development, aims to provide higher data throughput rates of over 1 gigabit per second to improve the user experience and to enable new applications such as transmission of multiple streams of high-definition multimedia data. To achieve these data rates, the Very High Throughput (VHT) physical layer specification has introduced new features, including wider bandwidth channels up to 160 MHz and 256QAM modulation. 802.11ac devices will need to meet more stringent specifications for RF performance, especially for error vector magnitude (EVM) over wider bandwidths, so it is important to have test tools that provide the best reference signals and EVM measurements, particularly for R&D and design validation.
