WiGig Wireless Gigabit Alliance

Last updated on 


WiGig (Wireless Gigabit Alliance) was an organization that developed the WiGig standard, also known as IEEE 802.11ad. WiGig aimed to provide high-speed wireless communication in the unlicensed 60 GHz frequency band, offering multi-gigabit per second data transfer rates for various applications. Let's delve into the details of WiGig and its significance:

Background:

WiGig was formed in 2009 as an industry association dedicated to developing and promoting the use of the IEEE 802.11ad standard. The alliance consisted of leading technology companies, including Intel, Microsoft, Qualcomm, Samsung, and others, collaborating to drive the adoption of high-speed wireless communication technologies.

IEEE 802.11ad:

IEEE 802.11ad, commonly known as WiGig, is a wireless communication standard operating in the unlicensed 60 GHz frequency band. Unlike traditional Wi-Fi (IEEE 802.11a/b/g/n/ac), which operates in the 2.4 GHz and 5 GHz bands, WiGig utilizes the much higher frequency of 60 GHz, enabling significantly higher data transfer rates.

Key Features and Advantages of WiGig:

  1. High Data Rates: WiGig is capable of delivering multi-gigabit per second data transfer rates, reaching speeds up to 7 Gbps. This makes it ideal for bandwidth-intensive applications such as ultra-HD video streaming, virtual reality (VR), and large file transfers.
  2. Low Latency: The use of high-frequency 60 GHz spectrum results in low transmission latency, which is critical for real-time applications like wireless docking, gaming, and augmented reality (AR).
  3. Short Range Communication: WiGig operates on a higher frequency band, which leads to shorter communication range compared to traditional Wi-Fi. However, this limitation can be beneficial in environments where security and limited interference are paramount.
  4. Beamforming: WiGig employs beamforming technology, enabling directional communication and better signal focus, resulting in improved range and link stability.
  5. Coexistence with Wi-Fi: WiGig is designed to coexist with existing Wi-Fi standards. Devices supporting WiGig can operate in 2.4 GHz and 5 GHz bands for backward compatibility while using 60 GHz for high-speed data transfers.

Use Cases of WiGig:

WiGig's high data rates and low latency make it well-suited for various applications, including:

  1. Wireless Docking: WiGig can be used for wireless docking, enabling laptops and other devices to connect to peripherals like monitors, keyboards, and storage without the need for cables.
  2. VR and AR: WiGig's high bandwidth and low latency are beneficial for virtual reality and augmented reality applications, where seamless and lag-free communication is essential for an immersive experience.
  3. Wireless Video Streaming: WiGig is ideal for streaming high-quality video content, including 4K and 8K videos, without any significant buffering or lag.
  4. Wireless Backhaul: In some scenarios, WiGig can be used for wireless backhaul to connect network segments, providing high-speed connectivity in dense urban areas or locations where laying cables is challenging.

Conclusion:

WiGig (Wireless Gigabit Alliance) and its associated IEEE 802.11ad standard were developed to provide high-speed, low-latency wireless communication in the 60 GHz frequency band. The alliance aimed to drive the adoption of WiGig technology in various applications, including wireless docking, VR/AR, and high-quality video streaming.
