WiGig

"IEEE 802.11ad" redirects here. Not to be confused with IEEE 802.1ad.

WiGig, or known as "Wireless-AD" or "60GHz Wi-Fi", refers to a set of 60 GHz wireless network protocols.

The name WiGig come from Wireless Gigabit Alliance, the original association being formed to promote the adaption of this technology, however the standard is now certified by Wi-Fi alliance.

History

In December 2012, the IEEE Standards Association published IEEE 802.11ad-2012 as an amendment to the overall IEEE 802.11 standard family.

The second generation WiGig standard, IEEE 802.11ay, is expected to be published in year 2019.

Specification

The WiGig MAC and PHY Specification, version 1.1 includes the following capabilities:

• Supports data transmission rates up to 7 Gbit/s – a bit over eleven times as fast as the highest 802.11n rate
• Supplements and extends the 802.11 Media Access Control (MAC) layer and is backward compatible with the IEEE 802.11 standard
• Physical layer enables low power and high performance WiGig devices, guaranteeing interoperability and communication at gigabit per second rates
• Protocol adaptation layers are being developed to support specific system interfaces including data buses for PC peripherals and display interfaces for HDTVs, monitors and projectors
• Support for beamforming, enabling robust communication at up to 10 meters. The beams can move within the coverage area through modification of the transmission phase of individual antenna elements, which is called phase array antenna beamforming.
• Widely used advanced security and power management for WiGig devices

Applications

On November 3, 2010, WiGig Alliance announced the WiGig version 1.0 A/V and I/O protocol adaptation layer (PAL) specifications. The application specifications have been developed to support specific system interfaces including extensions for PC peripherals and display interfaces for HDTVs, monitors and projectors.

WiGig Display Extension

• Supports wireless transmission of audio/visual data
• Enables wireless DisplayPort and other display interfaces that include the High-bandwidth Digital Content Protection 2.0 feature.
• Offers key A/V applications, such as the transmission of lightly compressed or uncompressed video from a computer or digital camera to an HDTV, monitor or projector

WiGig Bus Extension and WiGig Serial Extension. The WiGig Bus Extension (WBE) was available to members in 2011.

• Define high-performance wireless implementations of widely used computer interfaces over 60 GHz
• Enable multi-gigabit wireless connectivity between any two devices, such as connection to storage and other high-speed peripherals

Competition

WiGig competes with other 60 GHz frequency band transmission standards like WirelessHD in some applications.

Channels

Channel	Center (GHz)	Min. (GHz)	Max. (GHz)	BW (GHz)
1	58.32	57.24	59.4	2.16
2	60.48	59.4	61.56
3	62.64	61.56	63.72
4	64.8	63.72	65.88
5	66.96	65.88	68.04
6	69.12	68.04	70.2

Regional spectrum allocations vary by region limiting the available number of channels in some regions. The US is the only region supporting all six channels.
