[4] Usually it also supports additional link speeds (10, 100 or 1000 Mbit/s) in connection with autonegotiation, depending on the capabilities of the equipment at the other end of the cable.
The physical (PHY) layer transmission technology of IEEE 802.3bz is based on 10GBASE-T, but operates at a lower signaling rate.
This allows a single cable to provide both power and data for high-bandwidth wireless access points such as those that implement the 802.11ac and 802.11ax standards.
[10] The 2.5GBASE-T and 5GBASE-T standards also serve as an interim solution for achieving lower-cost and lower power consumption multi-gigabit network speeds.
Whilst Broadcom had announced a series of 2.5 Gbit/s transceiver ICs,[11] 2.5 Gbit/s switch hardware was not widely commercially available at that point.
[14] The competing MGBASE-T Alliance, stating the same faster Gigabit Ethernet objectives, was founded in December 2014.
