A high-speed wireless communication standard that communicates with a wide bandwidth using a high frequency of 60 GHz instead of 2.4 GHz or 5 GHz conventionally used for wireless communication "WiGig (IEEE 802.11ad)The Wi - Fi Alliance announced the implementation of the certification program of "Wi - Fi Alliance. This will be a gift to spread WiGig, and in 2017 it is expected that compatible equipment and compatible terminals will come out.

WiGig,Wireless communication standard enabling high-speed communication of large capacity in 2009It was created by the "Wireless Gigabit (WiGig) Alliance" that 15 organizations such as Microsoft, Intel, NEC, Panasonic gathered and started up. At the time of wireless communication in 2009, when the IEEE 802.11n with the maximum transmission speed of 600 Mbps was approved as an official standard in September, IEEE 802.11 g with the maximum transmission speed of 54 Mbps in the 2.4 GHz band and the maximum transmission rate IEEE 802.11a at 54 Mbps was used.

By the way, if a local area network (LAN) that transmits and receives data by wireless communication is "Wireless LAN (Wireless LAN / WLAN)", One of the" wireless LAN "communication standards is" IEEE "IEEE 802.11". However, despite being standardized, there was a problem that products from different vendors could not be connected at the beginning, so a trade association called Wi - Fi Alliance was created to promote the spread of wireless LAN. Interoperability by Wi-Fi Alliance When the brand name of the certified product that passed the authentication program is "Wifi". "WiGig" was made by a group called WiGig Alliance, so initially it was unrelated to Wi-Fi, but Wi-Fi Alliance later integrated the WiGig Alliance. "IEEE 802.11ad" and "WiGig" are almost synonymous, as IEEE has formulated the standard as IEEE 802.11ad and decided to implement a mutual authentication program conforming to WiGig.

The feature of WiGig is that it can perform high-speed communication of up to 7 Gbps in that it uses a band of millimeter wave of 60 GHz instead of the frequency band of 2.4 GHz · 5 GHz used in conventional Wi-Fi. IEEE has developed a standard called IEEE 802.11ac that can perform high-speed communication as high as 6.93 Gbps in the 5 GHz band almost in parallel with IEEE 802.11ad in the 60 GHz band, but the 11 ac has two bandwidths of 80 MHz and 160 MHz There is a difference of 1 Gbit / s with one antenna, while the maximum speed is 433.3 Mbps when one antenna and bandwidth is 80 MHz, the maximum is 6.93 Gbps if the bandwidth is 160 MHz with 8 antennas, 11 ad has one antenna. The maximum communication speed per IEEE 802.11ac bandwidth and number of antennas (MU-MIMO) is set to WikipediaIt is gathered as a table.

The 60 GHz frequency band has the merit that high speed communication is possible and the capacity of transmitted data can be increased, but on the other hand, it is difficult for the radio waves to travel in a straight line and it is difficult to wrap around obstacles and the radio waves are easily attenuated Disadvantage exists. For this reason, high-speed data communication at a short distance of about 10 m is considered as an application.

For example, when using a VR device that has begun to spread, if it is wired to a PC or a game machine, it will detract from the immersion feeling, which is a big advantage, but WiGig can follow this application as well. Furthermore, it is expected to become a standard that replaces the wired / wireless connection of peripheral devices such as HDMI and Bluetooth.

As a terminal compliant with IEEE 802.11ad, CES 2016 held in January 2016, China's peripheral device maker TP-Link has announced a router called "Talon AD7200", and NEC and Elecom are under development as well WiGig compatible router on display.

Now that the Wi - Fi Alliance 's implementation of the certification program of IEEE 802.11ad (WiGig) was announced, it is going to be the era of "WiGig" in 2017 at last.
