Features and Considerations

In theory, the HomePlug networking option is generally a more secure approach than wireless networking via 802.11b or Bluetooth because these wireless standards spread the data signal in an uncontrolled dispersion pattern to anyone within the signal radius wishing to listen to communications—at least this can be the case if the security settings for wireless local-area networking are left open as they come out of the box. HomePlug (and also HomePNA) is somewhat more plugand-play than wireless local area networks or standard Ethernet networking, although they are not as ubiquitous right now.

If you’re deciding which home-networking solution to purchase, Ethernet will generally give you the best security but can be costly, especially if you’re running a lot of cable from room to room. Wireless is good because there are no cables to run, but configuring the security settings for a secure network can take some time to learn and implement. HomePNA and HomePlug can be useful if you have a large number of devices to network across the home and wish to leverage your existing phone line or powerline infrastructure. These two will also increase in value when compared to Ethernet and wireless once more companies are providing suitable equipment and capable products.
