Keysight Technologies Cost Effective Design Verification of 802.11ac Wireless Transmitters and Receivers Application Brief Figure 1. Keysight 802.11ac MIMO R&D / DVT test solution. Accelerate R&D and design verification test of 802.11ac MIMO designs with a high speed, cost-effective test solution that provides accuracy, flexibility and scalability. Introduction The explosive growth of mobile devices and real-time applications, such as high-definition video, pushed current wireless local area network (WLAN) technology to its limits. The 802.11ac standard, built upon the success of 802.11n, addresses this challenge by providing a new set of WLAN capabilities offering increased speed, reliability and quality of wireless communications. Innovative design techniques and the desire to minimize manufacturing costs necessitate comprehensive testing during the R&D and design verification test stages of new WLAN devices. Design validation engineers must ensure that their 802.11ac designs will perform well under the most demanding modulation schemes, including MIMO spatial multiplexing configurations. This document describes how the Keysight Technologies, Inc. PXI modular hardware and related software applications provide a scalable and cost-effective radio frequency (RF) test solution enabling flexible signal generation and accurate signal analysis for testing 802.11ac transmitters and receivers. In today's high growth wireless market, the WLAN 802.11n standard reached limitations to meet the consumer's demand for higher WLAN capacity and higher quality mobile technology. Demand for higher throughput drove the development of a new set of capabilities addressed by WLAN 802.11ac. 802.11ac feature enhancements include:
