Gigabit and Power over Ethernet (PoE) are two networking technologies moving ahead in tandem as industrial users power remote Ethernet devices such as IP security cameras at 1,000 Mbps over existing CAT5 cable. The move to gigabit performance is also ramping up, in general, as users look for ways to strengthen their network infrastructures.
"The overall trends in the marketplace are the move to high speeds and Gigabit operation," Shane Duffy, fiber and telecoms product manager for B&B Electronics told Design News. "Video applications and other network consumers are playing a role in the need for speed and, with the price point of the Gigabit products coming down, it enables users to future-proof their network."

To be clear, I'm talking about interface speed to PCs here. Switched Ethernet is the norm these days, meaning that the network core can be at higher speeds than any given end system. But I'm sure that as prices for 1G Ethernet interfaces drop, 1G will become the norm in motherboards and adapter cards.
The 802.3af PoE allows up to 60W which is beneficial to all the edge clients like video cameras. With the use of midspans and PoE switches, it is possible to extend the 100m range.
I agree that 1000BaseT can be beneficial to many consumers and can simplify power & data connections for home or small offices when it comes surveillance & monitoring.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
