WiGig® (802.11ad) is a wireless standard that allows Wi-Fi devices to use the uncongested 60 GHz frequency band to provide multi-gigabit per second speeds. This standard provides extremely fast, low-latency wireless internet connectivity by using beamforming technology for sending a signal up to 10 meters. The focused transmission reduces interference even in the crowded places. The low power technology is five times more energy efficient than Wi-Fi and can act as a connection layer for devices that expect to connect via USB, DisplayPort, PCIe and HDMI. It is used for a wide range of applications that require high speed, data-intensive connections including, virtual reality, multimedia streaming, gaming, wireless docking, and enterprise. WiGig can provide data rates up to 8 Gbps.

WiGig was developed to complement the existing Wi-Fi 802.11ac standard (2.4 GHz and 5 GHz) by providing another, less congested frequency band at 60 GHz with high transmission speeds. Multi-band Wi-Fi CERTIFIED WiGig devices can seamlessly switch between the 2.4, 5, or 60 GHz bands, thereby improving the Wi-Fi experience for the user.

The WiGig standard was developed by the Wireless Gigabit Alliance in 2009/2010. In 2013, the Wireless Gigabit Alliance merged into the Wi-Fi Alliance with a plan to launch jointly certified devices.

Since WiGig operates in the 60 GHz band, it has shorter wavelengths, which do let the signals travel through walls thereby limit its range to the confines of a room, making it ideal for high data rate multi-media applications at home. Also, the 60 GHz band has a lot of attenuation which also limits the range of this technology. Click here to learn more about Attenuation of signals in the 60 GHz frequency band.

Popular uses for WiGig products include: 

  • Wireless docking between devices like smartphones, laptops, projectors, and tablets i.e., removal of HDMI cables.
  • Simultaneous streaming of multiple, ultra-high definition videos and movies
  • More immersive gaming, augmented reality and virtual reality experiences
  • Fast download of HD movies
  • Convenient public kiosk services
  • Easier handling of bandwidth-intensive applications in the enterprise
