WiGig is a wireless technology alliance using the 60 GHz frequency to increase wireless connectivity speed to multi-gigabit range. It offers backward compatibility, power management, security, and interoperability with other devices. WiGig has formed an alliance with the Wi-Fi Alliance and the Video Electronics Standards Association. It faces competition from the Wireless HD standard.
The Wireless Gigabit Alliance (WiGig) was formed by a diverse range of computer and computer software manufacturers to develop and sponsor wireless technology using the 60 GHz frequency. Their goal is to develop technology that does not require a license to use and increase the speed of wireless connectivity to reach the multi-gigabit range. The overall goal is to provide a seamless wireless connection between multiple devices in a single environment.
An early full version of a WiGig specification, called version 1.0, was created in late 2009. It has several major key points that highlight its functionality. The main point is the speed boost and it offers transmission speeds of up to seven gigabits per second (Gibt/s), which is ten times faster than its predecessor, the 802.11 specification. Another key point is backwards compatibility, and WiGig aims to work with current wireless network cards and technologies without the need for further updates. It also has accommodations for power management, security, and interoperability with other devices that use wireless (wifi) technology.
WiGig considers its use with other devices, such as high-definition television (HDTV) and personal computer (PC) peripherals, to be of paramount importance. To this end, he created the specifications known as WiGig version 1.0 audio/video (A/V) and I/O Protocol Adaptation Layer (PAL) specifications. PAL is a layer added to network broadcasting to help adapt to older standards. The A/V version 1.0 specification discusses uses of wireless transmissions for audio and video components, as would be used for digital cameras, and the PAL I/O version 1.0 specification discusses specifications for wireless connectivity for buses and extensions serials, such as those used in PC peripherals and other devices that use the 60 GHz frequency.
In addition to working with major companies, WiGig has formed an alliance with the existing wireless technology group known as the Wi-Fi Alliance. The Wi-Fi alliance was started to standardize the 802.11 standard, the predecessor of the WiGig standard. It also certifies wireless technology and the Wi-Fi alliance performs the same two functions for the Wireless Gigabit Alliance but for the technology using the 60GHz frequency. There was also a union formed with the Video Electronics Standards Association (VESA) to define the use of the new wireless standard with video devices.
While WiGig has a huge amount of support, they aren’t without competition. The Wireless High Definition (HD) standard sometimes uses the same 60 GHz. For the most part, Wireless HD is only used in portable devices and PCs. There is overlap between the two technologies, but they are not necessarily direct competition.
