Is a completely new approach compared to how 802.11ac was simply an extension to the previous 802.11n system.
It was developed by the trade association Wireless Gigabit Alliance (WiGig) which promotes the adoption of multi-gigabit speed wireless communications utilizing the unregulated 60 GHz frequency band.
It boasts much wider modulation bandwidth than all other wireless communication systems. It provides specific purpose short-range transmission connectivity that can support the extremely high data rates that are required by today’s consumer.
The system is also being developed to anticipate future markets needs such as the ability to stream large uncompressed data packets like 3D cinema in the home.
The costs of installation associated with 802.11ad Wi-Fi systems is uniquely lower than 802.11ac systems. The 60 GHz signal typically fails to penetrate objects such as a brick wall but can bounce off reflecting surfaces such as walls, ceilings, and floors using beamforming technology promoted in the WiGig system.
While roaming further away from a main room the system’s protocol can switch to utilize lower bands at a much lower data rate, but which may permeate through physical obstructions.
