This looks to be essentially the same as a cable or DSL modem. Plug in Ethernet on one end and it spits out wifi on the other end after doing RF cross conversion. Along with the modem is obviously a matching balun and AC blocking magic. As a 30 year user of BSR home automation I know that there are lots of devices on the line, specifically switching supplies that can really garbage up the data. Also in BSR land, crossing data path from one AC phase to another often requires a cross phase coupler. Wounder how this deals with these issues?
