From the horse’s mouth
Zyxel press release
Gigabit Ethernet is now becoming the order of the day with most current desktop and laptop PCs as well as network-attached-storage units being equipped with such a port. This is being taken further with routers having to be equipped with Gigabit Ethernet LAN (and WAN) ports in order to be considered fit for next-generation broadband Internet. This situation is also augmented with basic 5-port and 8-port Gigabit Ethernet switches now becoming more affordable.
At the moment, most HomePlug AV-Ethernet switches have been equipped with Ethernet ports that can work to a link speed of 100Mbps. This wouldn’t work in an optimum manner if you are connecting Gigabit-Ethernet-equipped computers to a HomePlug AV segment.
What Zyxel have done now is that they have announced a HomePlug AV Ethernet switch, the PLA4225, that uses Gigabit Ethernet ports as well as working to the unqualified 500Gbps extension of the HomePlug standard. This could allow you to provide a proper high-throughput HomePlug AV on-ramp for your desktop or laptop computer; fully-compliant next-generation-broadband “edge” router and NAS with these devices working at speed.
This is also in conjunction with them releasing the PLA4205 “homeplug” that works to the same powerline-network standard but uses a single Gigabit Ethernet socket.
Personally, what I would like to see for all of these 500Gbps HomePlug AV devices is that they are able to work to the full HomePlug AV2 standard once it is ratified and a proper firmware update is delivered.
But what I am pleased about is that the Ethernet connectivity of this HomePlug hardware is up to standard for people who use next-generation broadband Internet services with the proper routers.
