Considerations for 802.11ax Device Testing: High Efficiency Wireless Testing
Although the creation of new wireless standards promises many benefits to us as consumers—they introduce new design and test challenges. One exciting new technology is 802.11ax, also known as High-Efficiency Wi-Fi (HEW). HEW is an evolution to 802.11ac, and is expected to become a mainstream Wi-Fi technology by 2019. Designed to deliver better Wi-Fi performance in outdoor environments HEW uses several technologies that are new to Wi-Fi including narrower sub-carrier spacing, higher-order modulation schemes (1024-QAM), and Orthogonal Frequency Division Multiple Access (OFDMA). This presentation will provide a basic overview of the new features of 802.11ax, compare the standard to 802.11ac, and explain several practical considerations that it introduces for RF design and test.
