Powerwhat? Did you know that you could network your home without wires, by simply using your power outlets? Electronic Home recently discussed the advancements made to powerline networking technology.
Traditionally, powerline networking utilizes your existing power wiring to connect your computers to the internet. With simple devices plugged into both your computer(s) and modem/router, you can easily create a home network. The article gives you a good overview of how powerline networking works, and most interestingly, discusses the next soon-to-be released generation of the technology. What's promising about this advancement is that devices will be available not only to network your computers, but also share television and audio signals. This opens the door to being a bit closer to wire-free AV setups. We can't get rid of the need for power, so why not use it to do everything?
We've tried powerline networking before in the past, when we had problems getting our wireless signal throughout our apartment. We were fairly happy the results, but didn't splurge on high quality devices. If we tried it again, we would definitely invest in a more reputable device. Electronic Home offers a nice selection of manufacturers, if you are interested in adding this to your apartment.
