Wireless Gigabit (WiGig) is Multi-Gigabit Wireless Communication Technology, which was defined to meet the need for faster wireless connectivity for digital multimedia data transfer. Wireless Gigabit WiGig support for high-performance wireless implementations of Wireless HDMI, Wireless DisplayPort, Wireless USB (WUSB) and Wireless PCI Express. IEEE 802.11ad standard enables multi-gigabit wireless communications with data rates up to 7 Gbps in the 60 GHz band.

Wireless Gigabit WiGig Specifications

Wireless Gigabit WiGig MAC and PHY Specification enables data rates up to 7 Gbps, more than 10 times the speed of the fastest Wi-Fi networks based on IEEE 802.11n. It operates in the unlicensed 60 GHz frequency band, which has much more spectrum available than the 2.4 GHz and 5 GHz bands used by existing Wi-Fi products. This allows wider channels that support faster transmission speeds.

The Wireless Gigabit WiGig specification is based on the existing IEEE 802.11 standard, which is at the core of hundreds of millions of Wi-Fi products deployed worldwide. IEEE 802.11ad is an amendment to the 802.11 standard that enables multi-gigabit wireless communications in the 60 GHz band. New devices with tri-band radios will be able to seamlessly integrate into existing 2.4 GHz and 5  GHz Wi-Fi networks.

The Wireless Gigabit WiGig specification enables a broad range of advanced uses, including wireless docking and connection to displays, as well as virtually instantaneous wireless backups, synchronization and file transfers between computers and handheld devices. Wireless Gigabit WiGig support for high-performance wireless implementations of HDMI, DisplayPort, USB and PCI Express.

Modulation & Coding Scheme (MCS) of Wireless Gigabit (WiGig)

The specification supports two types of modulation and coding schemes, which provide different benefits. Orthogonal frequency-division multiplexing (OFDM) supports communication over longer distances with greater delay spreads, providing more flexibility in handling obstacles and reflected signals. Furthermore, OFDM allows the greatest transmission speeds of up to 7 Gbps. Single carrier (SC) typically results in lower power consumption, so it is often a better fit for small, low-power handheld devices. SC supports transmission speeds up to 4.6 Gbps.
