[Topic] "PLC" that can be communicated by inserting it in an outlet, why again? New application-Home appliances Watch

電気のコンセントを介して建物内などの高速ネットワーク接続を可能にするHD-PLC

Do you know the PLC communication device? The official name is "Power Line Communication", and in Japanese, it is called "power line transport communication".Easy to say, without a new LAN cable, you can build a communication environment through the power line of the existing outlet.Data communication can be performed by connecting the PLC adapter to two outlets.

If you've been involved in the Internet for a long time, you might think, "It was a long time ago but it disappeared?"Certainly, in the original PLC, the communication speed was slow and there was a problem with compatibility, and Wi-Fi (wireless LAN) appeared and Wi-Fi became rapidly spread with the spread of smartphones.The PLC rarely sees it in the form of being pushed by it.

However, around 2017, Panasonic has become a flag, and the new generation of "HD-PLCTM * 1" has begun to be reviewed.One of the reasons is actually the spread of Wi-Fi.

* 1 The name of the high -speed power line communication method proposed by Panasonic is a registered trademark or trademark in Japan and other countries.

While Wi-Fi has become more convenient year by year, the radio waves of Wi-Fi are blocked by the walls of the room, the ceiling and floors of each floor, and in some cases even one door, and the uneven radio waves increase.There is.

On the other hand, the demand for communicating anywhere in the house, like IoT home appliances that are convenient to connect to the Internet, is growing significantly.With Wi-Fi, the radio waves become extremely weak on the walls and doors, but it is easy to cross the door and each floor with an HD-PLC that uses an outlet.Just insert the PLC adapter into the outlet to complete the LAN.* 2

If necessary, it can also connect wireless LAN access points to HD-PLC, so it can be used to collaborate with access points.PLC, who is dying with the spread of Wi-Fi, will help Wi-Fi this time.
