This report addresses recent or soon coming enhancements in 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 does 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. 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. 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. 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. IEEE standard in the development: P802.11ax, which stretches Wi-Fi characteristics beyond imaginable just a few years ago.
  • 7. WAVE 802.11p - Dedicated Short Reach Communications 5.9 GHz - contribution of Wi-Fi to the development of the connected car.
  • 8. 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.

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 2016-2019.
