Progress in Wi-Fi Development Technologies, Applications and Markets

This report addresses advanced developments in one of the most established and powerful wireless technology – Wi-Fi. Originated in the 20 century, this WLAN family belongs to a very small group of communications technologies that do not getting old 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.

The report goal is to analyze 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 has 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 the recent years, 802.11n products dominated the Wi-Fi market; but this technology is gradually losing its leading position to newer or more specialized 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’ 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.
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 works in unused windows of the TV spectrum and in a future will use 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 the wide spectrum of characteristics.
5. Sub - 1 GHz Wi-Fi (excluding White Spaces) – 802.11ah.
6. IEEE standards in the development: P802.11ax and P802.11ay, which are stretching 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.

This report is important to a wide audience of researches, technical and sales staff involved in the developing of WLANs and based on them network infrastructures. It is recommended for both service providers and vendors that are working with related technologies. The report also helps to understand issues associated with relationship between discussed systems and other technologies.

The report also includes the survey of 802.11ah-realated patents published in 2015-2016.
