This report addresses recent or planned enhancements to one of the most established and powerful wireless technology - Wi-Fi. Originated in the 20s century, this WLAN family belongs to a very small group of communications technologies that do not getting obsolete with time. The family continues to grow adding new members that bring WLAN to the forefront of today innovations in communications with multiple applications and pushing up the limits in performance. Wi-Fi will support and strengthen 5G networks making them more flexible and efficient.

The report goal is to analyze recently introduced or still in the development advanced Wi-Fi technologies, their applications and marketplace. It also surveys related industries.

In particular, it addresses such developments as:

  • 1. 802.11n (Wi-Fi 4). The technology already produced a multi-billion market, improving such communications characteristics as the rate of transmission, coverage and other. It significantly increased the spectrum of Wi-Fi applications. In recent years, 802.11n products dominated the Wi-Fi market; but this technology is gradually losing its leading position to newer members of the Wi-Fi family, such as:
  • 2. 60 GHz Wi-Fi - 802.11ad/ay. This is the Wi-Fi industry response on the users' new requirements to support gigabits per second transmission rates over shorter ranges for such applications as a home/office distribution of HDVD and similar bandwidth-hunger applications. The report addresses specifics of 60 GHz channels and details WiGig/802.11ad technology. It also introduces the NG 60 GHz 802.11ay standard.
  • 3. White Spaces Wi-Fi (White Wi-Fi - 802.11af). This technology allows utilizing the property of sub-gigahertz transmission together with Wi-Fi advances. It utilizes unused windows of the TV spectrum and will work with Cognitive Radios.
  • 4. Sub - 6 GHz Wi-Fi - 802.11ac (Wi-Fi 5). This development allows gigabits per second speed and improves characteristics of IEEE 802.11n technology in wide spectrum of characteristics.
  • 5. Sub - 1 GHz Wi-Fi (excluding White Spaces) - 802.11ah.
  • 6. 802.11ax (Wi-Fi 6), which stretches Wi-Fi characteristics beyond imaginable just a few years ago.
  • 7. Wi-Fi 6E - 802.11ax in the 6 GHz band
  • 8. WAVE 802.11p - Dedicated Short Reach Communications 5.9 GHz- contribution of Wi-Fi in the development of the connected car.
  • 9. Other.

The report details technical and marketing specifics of these types of WLAN technologies as well as surveys their industries and shows that Wi-Fi 6 is ready to meet some 5G requirements; with incoming Wi-Fi 7 bringing even wider spectrum of advanced characteristics.

The report was developed for technical and managerial personnel working on the Wi-Fi-related projects to give them better understanding specifics of this family technologies and markets.

The report also includes the survey of Wi-Fi technologies related patents for 2018-2022.
