  The Wireless Gigabit Alliance (WiGig) and IEEE 802.11ad are developing a
multigigabit wireless personal and local area network (WPAN/WLAN) specification
in the 60 GHz millimeter wave band. Chipset manufacturers, original equipment
manufacturers (OEMs), and telecom companies are also assisting in this
development. 60 GHz millimeter wave transmission will scale the speed of WLANs
and WPANs to 6.75 Gbit/s over distances less than 10 meters. This technology is
the first of its kind and will eliminate the need for cable around personal
computers, docking stations, and other consumer electronic devices.
High-definition multimedia interface (HDMI), display port, USB 3.0, and
peripheral component interconnect express (PCIe) 3.0 cables will all be
eliminated. Fast downloads and uploads, wireless sync, and
multi-gigabit-per-second WLANs will be possible over shorter distances. 60 GHz
millimeter wave supports fast session transfer (FST) protocol, which makes it
backward compatible with 5 GHz or 2.4 GHz WLAN so that end users experience the
same range as in today's WLANs. IEEE 802.11ad specifies the physical (PHY)
sublayer and medium access control (MAC) sublayer of the protocol stack. The
MAC protocol is based on time-division multiple access (TDMA), and the PHY
layer uses single carrier (SC) and orthogonal frequency division multiplexing
(OFDM) to simultaneously enable low-power, high-performance applications.
