Looking at ways of increasing the amount of power transmitted, IEEE has defined IEEE 802.3bt "4PPoE" in September 2018. The standard introduces two additional power types: up to 51 W delivered power (Type 3) and up to 71.3 W delivered power (Type 4). Each pair of twisted pairs needs to handle a current of up to 600 mA (Type 3) or 960 mA (Type 4). Additionally, support for 2.5GBASE-T, 5GBASE-T and 10GBASE-T is included. This development opens the door to new applications and expands the use of applications such as high-performance wireless access points and surveillance cameras. PoE is also used in the automotive industry.
