## Background
BACKGROUND OF THE INVENTION
The present invention relates generally to power line networking techniques. More particularly, the invention provides an apparatus for a high speed power line network using a power plug outlet strip for a computing environment. Merely by way of example, the invention has been applied in a local area network environment, but it would be recognized that other applications exist. The invention can also be applied to building area networking, home networking, office networking, apartments, any combination of these, and other networking applications.
Telecommunication techniques have been around for numerous years. In the early days, a communication technique known as telegraph was developed. Telegraph generally transferred information from one geographical location to another geographical location using electrical signals in the form of “dots” and “dashes” over transmission lines. An example of commonly used electrical signals is Morse code. Telegraph has been, for the most part, replaced by telephone. The telephone was invented by Alexander Graham Bell in the 1800s to transmit and send voice information using electrical analog signals over a telephone line, or more commonly a single twisted pair copper line. Most industrialized countries today rely heavily upon telephone to facilitate communication between businesses and people, in general.
In the 1990s, another significant development in the telecommunication industry occurred. People began communicating to each other by way of computers, which are coupled to the telephone lines or telephone network or other communication network. These computers or workstations coupled to each other can transmit many types of information from one geographical location to another geographical location. In general, there has been various types of computer networks, including local area networks, commonly called LANs, and wide are networks, commonly called WANs.
Local area networks have been used to connect computers in a smaller geographic region than wide area networks. Most local area networks rely upon dedicated cables to transmit the communication signals through the network. An alternative way of transmitting such communication signals through non-dedicated cables but through a power supply network is referred to as Power line Communication, commonly called PLC. Power line communication relies upon pre-existing power lines that are used to supply electrical power distributed through buildings, such as homes and office structures. Conventional PLC relies upon radio frequency technologies. Although power line communications have been successful in part, many limitations still exist.
For example, power line communication generally has limited capability due to lack of infrastructure. That is, power line networking has not been “mainstream,” Power line networking has little or almost no infrastructure. Additionally, power line network devices are lacking and simply do not exist on a wide scale. In conventional office settings in the United States, power line networking is absent and almost non-existent. These and other limitations have been described throughout the present specification and more particularly below.
From the above, it is seen that improved techniques for power line networks are highly desired.

one or more AC power outlets coupled to the surge protector, the one or more AC power outlets being spatially disposed on a first portion of the outer region of the housing member;
an on/off switch coupled between the one or more AC power outlets and the surge protector, the on/off switch being adapted to turn “on” or “off” the one or more AC power outlets;
a power line device coupled to the AC power line, the power line device being adapted to process a data signal from the AC power line in a first format to a second format;
a powerline coupler for coupling the power line device to the AC powerline, wherein the coupling of the power line device to the AC powerline is achieved using three phases, wherein the data signal from the AC powerline is injected directly into each of the three phases, and wherein the three phases are not coupled to each other upon the injection;
a switching power supply coupled to the AC power line, the switching power supply being adapted to convert an AC power signal into a DC signal for use with the power line device;
a first output port coupled to an first input/output of the PLC device; and
an Nth output port coupled to a second input/output of the PLC device; where N is an integer greater than 1.

11. A method of using a power strip apparatus having power line networking capability, the method comprising:
providing a housing member, the housing member including an outer region and an inner region, the housing member also including an AC power line coupled to the housing member, the AC power line including a male connector device;
supplying AC power to the power line and through a surge protector coupled to the AC power line, the surge protector within a first portion of the inner region of the housing member;
transferring the AC power from the powerline after the surge protector to one or more AC power outlets coupled to the surge protector, the one or more AC power outlets being spatially disposed on a first portion of the outer region of the housing member;
coupling, in three phases, the AC power line to a power line device for transferring at least a data signal, wherein the data signal from the AC powerline is injected directly into each of the three phases, and wherein the three phases are not coupled to each other upon the injection;
transferring the data signal in a first format from the AC power line to the power line device coupled to the AC power line, the power line device being adapted to process the data signal from the AC power line in the first format to a second format;
transferring one or more first portions of the data signal in the second format to a first output port coupled to an first input/output of the PLC device; and
transferring one or more Nth portions of the data signal in the second format to an Nth output port coupled to a second input/output of the PLC device; where N is an integer greater than 1.
