I came over a review at ars this morning reviewing this product: Ubiquiti Ethermagic. It is a Gigabit over Power cable switch solution. What is more interesting is that it also supplies devices connected to the ethernet with power.
Would be great if you guys at Mikrotik comes up with a similar product or better product, what about embedding the power input in the switches/routers in to this type of network, eliminating an additional box that we need to set up. The wireless wire might be good, but for apartments in crowded WiFi networks with lots of armed concrete walls in between it is not that good.
There are more advanced solutions on the market. E.g. https://www.devolo.com/. You could embed this into your din-rail electrical installation to get best signal everywhere and there are devices with powerline, wifi-ac and socket pass through integrated.
This is just powerline over ethernet. It is a good thing, but far from a magic solution. I used one, from TP-Link, in my apartment. It worked great, until it didn’t. Somewhere the building, someone was using something that wrecked my connection - too much noise on the line. Never found who it was, never found out what it was. Sometimes it worked, sometimes didn’t.
After this experience, I gave up on this tech. Wireless interference is hard enough - but I can switch channels. Powerline, not so much.
This depends in how much effort you put into the installation (same as with wifi at home). Most people just plug in 2 adapters somewhere and fail. Most I hear do not even install the sw of the vendor to fiddle out the best socket to place adapters into.
You should connect central on all phases. You could work with filters and signal bridges to work around problems within your installation.
If done right it is a very clean install and works very good. One device/room which provides wifi. There are no cables at all despite power in the wall.
A very clean install when one have the luxury of a not shared phase - usually this is the case of houses (as powerline will not cross transformers). At an apartment building… not so much.
