Powerline networks are not the most popular, especially with advancements in wireless technology, but they are still being actively developed. TP-LINK specifically mentions a few use cases: going through cement or certain soundproof walls, going across metal beams and studs, and going further than is practical under FCC broadcast power limits.

Today at CES, TP-LINK has announced the TL-PA8030 AV1200 Gigabit Powerline networking adapter. This product differentiates itself from previous offerings with “HomePlug AV2 MIMO”, which is an acronym that is normally applied to wireless technology with multiple antennas. It is basically the same thing in this case, because the adapter uses all three prongs.

Basically, how electrical sockets work is that you have two main prongs, one of which has an alternating voltage applied to it that averages out to about ~115V RMS over a cycle (relative to the other prong). When that wire is connected to a second one, at whatever is considered “neutral” voltage, it creates an electrical current with that drop (or rise) in voltage. A third plug, which is held at the ground's voltage, takes away any excess buildup from friction, wires that are shorted to the case, and so forth.

For this product, this means that one connection will be on the same circuit as a high-voltage, 60Hz signal, and the other will be mixed with ground noise. Keep in mind, the alternative to powerline networking is broadcasting on unregulated, wireless spectrum, so humanity is not afraid to send a signal through some nasty noise. Still, it is good to stop and think about what these engineers have been able to accomplish: broadcasting two signals, down two really nasty (and in different ways) circuits, and combine them for increased performance with multiple devices.

This out of the way, the specifications themselves are brief: it is three Gigabit (1.2 Gbps total) network connections that communicate through A/C plugs. It is backwards compatible with older TP-LINK HomePlug AV adapters (AV1000, AV600, AV500, AV200, and of course other AV1200s).

No pricing information, but TP-LINK is targeting Q3 2015 for this AV1200.
