Powerline Networking Guide
HomePlug
Powerline networking has
existed in a few forms in the past, the lastest specification is
called HomePlug and runs at 14Mbps. HomePlug uses your
existing home electrical wiring to transfer data.
HomePlug does not
interfere with your existing electrical equipment or home automation
devices like X-10, CEBus, and LONworks. HomePlug also encrypts
all data with 56bit DES encryption to ensure that your neighbors can
not evesdrop on your network traffic. Note: encryption
is usualy not enabled by default and must be 'turned on' using
software proided by the devices manufacturer.
The HomePlug specification incorporates a
technology called PowerPacket. This new technology is what
makes HomePlug different from the old powerline networks.
PowerPacket eliminates noise from electrical appliances like hair
driers and televisions plus it offers security.
Powerline network adapters
come in PCI and USB versions but are very expensive right now -
about $125 to $150 per computer.There are also Powerline to Ethernet
bridges and Powerline broadband routers with ethernet bridges built
in in the same price range.
