Powerline Comms market still a mess, Wi-SUN hits 91mn units

There is a long and somewhat torrid history of using PLC to connect grid assets. In general, it works well for the high and medium voltage lines, and can work well for automated meter reading. This makes PLC quite useful for grid operators, as it can be used to send and receive commands, and also poll meters for their usage. You can see how PLC could be used in smart grid deployments, but there are also many in-home protocols that make use of PLC technologies, such as KNX, X10, HomePlug, and G.hn. However, using a wireless protocol to do the same provides you with an out-of-band (OOB) channel, which adds a lot of redundancy to the network. If a powerline…
