目錄

This report reflects a never-ending process of enhancing Wi-Fi technologies and it updates Practel reports published in 2010-2013.

In particular, it addresses such relatively recent developments:

  • 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.
  • 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.
  • 3. White Spaces Wi-Fi (super Wi-Fi - 802.11af). This technology allows utilizing the property of sub-gigahertz transmission together with Wi-Fi advances. It utilizes unused windows of spectrum and shows unlimited abilities of Wi-Fi.
  • 4. Low-consumption Wi-Fi. Until recently, WLAN technologies could not compete with ZigBee, UWB and other low-consumption technologies. The creation of low-consumption Wi-Fi chips opened the doors for such applications as WSN in healthcare, manufacturing, building automation and many others.
  • 5. Sub -6 GHz Wi-Fi - 802.11ac. This development allows gigabit per second speed and improves characteristics of IEEE 802.11n technology in the wide spectrum characteristics.
  • 6. Sub- 1 GHz Wi-Fi (excluding White Spaces) - 802.11ah.

The report addresses technological, standardization and marketing features of these recent additions to the 802.11 family; it also includes a survey of vendors and their portfolios.

Target Audience

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 infrastructure. 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.
