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:
