In your home computer system, you want to have all the computers either tied to each other to share data or to allow any of the computer powerline network adapter. Either way, you will need a router, wires or cables, all kinds of extra hardware. Or will you? With using wireless technology you do not have to run wires through your kitchen, down your halls to the study or bedroom desk areas to where the computers are.
This technology has come a long way in the last few years. It used to be that I would go outside to work and I had a ton of cables and wires trailing after me. Now, I just pick up my laptop and out I go. I don't have to worry about plugging into an electrical outlet, although I could, and the signal is plenty strong enough to make me happy with the speed of the internet downloads. I just sit in the morning sunlight, getting my full allotment of Vitamin D for the day, drink my coffee and read the morning news.
If I want to work during the morning, I come inside, go to my office, plug my computer in and whale away at the keyboard. I really don't think about having a good connection to the internet because it is always there. No matter where I am in the house, my connection is secure, at least downstairs.
If I have to go upstairs to the front office up there, I have to change the modals of operation. I have to use an Ethernet cable and best powerline adapter and plug in the power grid of the house. So in our house we use both the wireless capabilities of the powerline modem and the technology of the internet over the power lines in the house.
All computers, laptops and desktops, have an Ethernet connection, so there is no extra card that you need to add to your computer. The only difference is that your router or wireless modem will have the powerline capabilities built right into it. In addition, you would need to have powerline-Ethernet adapters at any electrical plug that you would need to use a computer and the internet or the home network. Remember, you can unplug one of the adapters and move it with you if you want to do that.
This is the best of both worlds, the wireless computer network/internet connection and the no new wires, powerline-Ethernet connection any where you want to work.
Say, you have a backyard office, as long as the power line to your office comes from the same source as your home, i.e., no separate electrical breaker box, you can use the same internet connection as if you were in the same roof.
Either way you connect to the internet and home powerline adapter switch, you have the freedom of movement, choice of location and a great connection no matter where you are in your home environment.
