目次

This report concentrates on recent advances in the development of the Wi-Fi technology. Wi-Fi (IEEE 802.11) is the most powerful, well-established and highly marketable wireless technology. Billions of Wi-Fi chips are at work, providing support for many industries, including healthcare, industrial and building automation, consumers' electronics and other.

The report shows that the work to enhance the Wi-Fi technology has never stopped.

In particular, it addresses such 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. This is the Wi-Fi industry response on the users' new requirements to support gigabits per second rates of transmission 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). This technology allows utilizing the property of sub-gigahertz transmission together with Wi-Fi advances.
  • 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.

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 related products.
