Powerline adapter standard: Homeplug or G.hn

HomePlug AV2 MIMO This illustration provided by the HomePlug Alliance shows how MIMO works when applied to powerline networking.

No mixing: HomePlug and G.hn are incompatible

Powerline networking can be faster and more reliable than Wi-Fi when you need to serve client devices that are behind very thick walls—particularly concrete or masonry—or that are multiple stories away from your router. But the two powerline standards discussed here are not interoperable, so choose one or the other.

To create a powerline network, plug one adapter an AC outlet near your router and connect it to your router using an ethernet cable. Plug other adapters into AC outlets near the devices you want to add to the network, and then connect those devices to the adapters using ethernet cables. Don’t plug the adapters into outlet strips or surge protectors, as those devices might consider the data packets traveling over the wire to be noise and filter them out.

Both G.hn and the latest version of HomePlug—HomePlug AV2 MIMO—use a variant of the multiple input/multiple output technology you’ll find in 802.11n and 802.11ac network devices. Using MIMO, a powerline device will utilize all three wires in an electrical cable, transmitting data on any two pairs: Line/Neutral, Line/Ground, Neutral/Ground, and so on to achieve theoretical TCP throughput of up to 1.2Gbps. Earlier HomePlug devices transmit using only the Line and Neutral wires; SISO (Single Input, Single Output) HomePlug AV delivered maximum throughput of 600Mbps.

While the HomePlug Alliance certifies powerline products bearing the HomePlug brand as interoperable, that doesn’t mean you’ll get optimal performance from a network formed by a mix of HomePlug AV2 MIMO brands. You can mix powerline and Wi-Fi devices, though, and most people do. You can also buy powerline-based Wi-Fi range extenders that create local wireless access points in rooms where your Wi-Fi signal can’t reach. Powerline is a fantastic solution when Wi-Fi alone doesn’t cut it, but Wi-Fi is much more convenient if for no other reason than Wi-Fi adapters are built into nearly every device (smartphones, laptops, tablets, media streamers). Plus, there’s the whole “no wires” thing; heck, even newer set-top boxes and DVRs have gone wireless.

At last,Wondertek Technology can provide both Homeplug and G.hn standard powerline products. The system is very complete and can be selected according to customer needs.(As below topology)
