Unlike previous amendments (e.g., IEEE Std 802.11ac, IEEE Std 802.11n) which were focused mainly on increasing the peak throughput, 802.11ax focuses on achieving Higher Efficiency (HE) and improving metrics that reflect user experience, such as average throughput per station. This was achieved by better physical layer efficiency and spectrum utilization, flexible multi-access and scheduled transmission schemes, increasing the spatial reuse, and improving interference management between neighboring networks, particularly in dense environments.</p><p>In this training, learners will gain an overview of the features and optimizations introduced by IEEE 802.11ax to the Physical (PHY) and Medium Access Control (MAC) layers, which lead to these improvements. The first day of the course will focus on the PHY layer and the second day of the course will focus on the MAC layer.</p><p><em>What you will learn:</em></p><ul><li>Main physical layer (PHY) features introduced in 802.11ax and their benefits</li><li>Details of 802.11ax PHY numerology and tone plan for each bandwidth</li><li>The four PHY Protocol Data Unit formats and their usage</li><li>Important topics in the 802.11ax PHY operation including sounding sequences, preamble puncturing operation, and spatial uses concepts</li><li>Main Medium Access Control (MAC) features introduced in 802.11ax and their benefits</li><li>MAC support for downlink and uplink multi-user operation</li><li>Use of Basic Service Set (BSS) color for differentiating intra-BSS vs inter-BSS PPDUs, two network allocation vector (NAV) operation, spatial reuse modes, and details for multi-user (MU) enhanced distributed channel access (EDCA) operation</li><li>Negotiation and utilization of target wake times (individual and broadcast), operation mode indication</li><li>Dynamic fragmentation, multi-traffic identifier (TID) aggregation and variable size BlockAck frames</li><li>Enhancements to active/passive scanning and network operation in the 6 GHz band</li><li>Extending the range of a BSS, use of transmit opportunity (TXOP)-based Request To Sent (RTS)/Clear To Send (CTS) exchanges</li></ul><p><strong>Courses included in this program:</strong></p><ul><li><span style="background-color: initial;"><span style="background-color: initial;"><a href="https://iln.ieee.org/Public/ContentDetails.aspx?id=0D2076B372AC491B849C0586BB03DED1" rel="noopener noreferrer" target="_blank">IEEE 802.11ax: An Overview of High-Efficiency Wi-Fi (Wi-Fi 6) Physical Layer</a></span></span></li><li><a href="https://iln.ieee.org/Public/ContentDetails.aspx?id=D83376AA22D944BDADE59B3BE57D1440" rel="noopener noreferrer" target="_blank">IEEE 802.11ax: An Overview of High-Efficiency Wi-Fi (Wi-Fi 6) Medium Access Control Layer</a></li></ul><p><strong>Course Program Length</strong>: 6 hours</p><p><strong>Who Should Attend: </strong>All levels of technical engineers, Wireless Engineers, Systems Engineers, Technical Managers/C-Level Executives, Network Engineers, Software Engineers, Research Engineers, Lead Developers, Computer Systems Researchers, Application Architects, Product Development Engineers, Product Developers, Product Managers</p><p><strong><span style="color: rgb(226, 80, 65);">Instructors</span></strong></p><p><strong>Bin Tian</strong>, Senior Director of Technology in Wireless, Qualcomm, Inc.</p><p><strong>Alfred Asterjadhi</strong>, Systems Engineer in Wireless, Qualcomm, Inc.</p><p><strong>Publication Year</strong>: 2023</p><p><strong>ISBN</strong>: 978-1-7281-7833-2</p> </p> <hr /> <script type="text/javascript"> function XploreLogin(strURL) { window.location.href = strURL;
