Yes, although if you have not decided to buy these adapters, please don‘t. I strongly advise you to get 1000 Mit/s ones. They do not cost a lot more but they allow the signals to travel farher and with in the end greater speed. Powerline speed marks the starting point, what you get at the other end depends. If you start with higher Mbit/s you will have more speed at the farther away endpoint.

You would still be able to improve throughput if the faster devices are used at critical locations to optimize your network.
