Motivation and Context

Wireless-Fidelity (Wi-Fi) is among the greatest success stories of this new technology era, and its societal benefits are known to most of the world population. Since Wi-Fi has become an essential part of the home, and a key complementary technology for both enterprise and carrier networks, its importance is expected to continue growing beyond 2023, as the newly defined generation of more capable Wi-Fi products —Wi-Fi 6, based on the most recent Institute of Electric and Electronic Engineers (IEEE) 802.11ax specification— becomes widely available. The requirements of wireless data services, however, will continue to increase in many scenarios such as homes, enterprises and hotspots, beyond the capabilities of Wi-Fi 6. To meet such expectations, the Wi-Fi community is aiming high and has already initiated discussions on new IEEE 802.11 technical features for bands between 1 and 7.125 GHz. The creation and standardisation of the next generation of Wi-Fi technology beyond IEEE 802.11ax—referred to as Extremely High Throughput (EHT)—targets to increase peak throughput and ensure that Wi-Fi meets the requirements set by incoming applications, thereby maintaining—or even augmenting—its appeal to consumers.

The scope of the proposed tutorial is to provide the research community with
1) a self-contained overview of Wi-Fi’s fundamentals,
2) a survey of the main technical features defined by the new 802.11ax standard, and
3) fresh updates on the most recent outcomes and directions related to the next generation of Wi-Fi technology beyond 802.11ax directly from the IEEE
802.11 EHT standardization meetings.

EuCNC is the perfect occasion to provide a digestible summary about Wi-Fi’s current technology status and prospective, since the first 802.11ax-compatible products are just reaching the market and the specific objectives and features of EHT are currently being shaped.
