The growing need for 10Gb transmission over ethernet has seen a large increase in the deployment of Cat6A in recent years.
In many cases networks are made up of a combination of Cat6 to the desktop and Cat6A to Wireless Access Points. However, Cat6A to the desktop is a must for networks where a stable 10Gb connection is required. Typically in media, for video editing etc, or for streaming applications. Or simply for when running multiple applications at once.
As the demand placed on cabled and wireless networks continues to grow, Cat6A will soon overtake Cat6 the dominant standard.
