For those who wanna be free from wired data network but feeling uneasy with data security issue of wireless or WiFi data connection, you can make use of the Panasonic AC Outlet Internet Connection Kit to let you freely move around in your house or office space.
The AC Outlet Internet connection kit makes use of the building’s electrical wiring to link your computer with the broadband modem for Internet connection. In short, it’s an adaptor that can turn any mains outlet into a network point. Have one adaptor connected to your Internet modem (using a LAN cable) and plugged into the mains outlet. And you can then move around with your laptop from room to room, as long as you have another adaptor plugged into the mains outlet of the room which you’re in.
Tip for the paranoids, this is a more secure way of having your data transmitted over electrical wiring instead of transmitting in the air. Furthermore, the adaptor also adds extra security to your data by having AES 128-bit encryption. And it delivers much faster in speed, with 170Mbps, than any wireless network.
