I use them to convey my screen on my TV to play in the sofa with a Xbox360 controller without son. My first attempt was to connect directly to my local network. This works very well but the network is saturated (broadcast). I wired the two devices directly to each other and the problem is solved.
I add that to operate they only need two pairs network (100 Mbit Ethernet wiring). I have taken on a wired network link for these devices and traditional network socket for 100 Mbit LAN.
Also when the transmission of the screen apparatus works a little heat.
