IEEE 802.11ad introduces enhancements to the IEEE 802.11 standard, specifically targeting very high throughput in the unlicensed 60 GHz band. The 60 GHz band offers significantly more available bandwidth compared to the 2.4 GHz and 5 GHz bands.

Within the 60 GHz band, communication can occur across four channels, each with a substantial width of 2.16 GHz. This wide spectrum allows for the potential of achieving impressive bit rates, reaching up to 7 Gbit/s.

However, it’s important to note that the 60 GHz band has limitations, particularly in terms of range when compared to the 2.4 GHz and 5 GHz bands. Nevertheless, IEEE 802.11ad is intentionally designed to facilitate wireless connections between computers and other devices within a network. For instance, it can serve as a wireless replacement for cables, enabling connections such as HDMI video links to displays or USB connections to various terminal equipment.

Since IEEE 802.11ad primarily functions as a “cable replacement” for device connectivity within close proximity, the relatively limited range is not a significant issue. It is intended to coexist with IEEE 802.11a/b/g/n/ac, which handle TCP/IP connectivity within the network and to the internet.

The development of IEEE 802.11ad initially began within the Wireless Gigabit Alliance (WiGig) but was subsequently transitioned into the IEEE 802.11ad specification.00
