We just learned this morning that the IEEE has approved the new specifications covering 2.5 Gbps and 5 Gbps Ethernet cables, with the new 802.11bz performance specification.

The approval confirms that the work done but still incomplete at the end of last year, the interface between the Media Access Control (MAC) and the physical (PHY) layers has been completed and set to go.

In December 2015, N-Base-T Alliance leader Peter Jones explained to us that the IEEE wanted the new 802.11bz spec to provide connectivity to the latest-generation 802.11ac Wi-Fi devices without replacing older and existing Cat 5e/6 internet cabling.

``With the astonishingly huge installed base of Cat5e/6 unshielded twisted pair (UTP) copper cable—70 billion meters and 1.3 billion outlets at last count—organizations across hundreds of industries were facing an impending crisis.``

``A new generation of 802.11ac Wave 2 devices was on its way and looking directly at a 1Gb/s Cul-de-Sac,`` he added.

The IEEE's approval today means that equipment vendors and Ethernet cable makers can accelerate the rollout of products which had already began, in the time-honoured practice of rolling pre-standard product.

Originally, work on the 802.11bz specification began more than two years ago. The N-Base-T alliance board consists of Aquantia, Cisco, Intel, Marvell, NXP and Xilinx. We'll keep you updated on more IEEE developments as they happen.
