Abstract

A powerline network switch apparatus is coupled to a first datasource connection. The apparatus has a second datasource connection, which is coupled to the first data source connection. The apparatus also has a powerline device coupled to the second datasource connection. Preferably, the powerline device is adapted to receive and transmit information in a first format from the second data source connection and adapted to receive and transmit information in a second format. The apparatus also has a virtual local area network device including a first input/output port and a plurality of second input/output ports. Each of a plurality of modem devices is coupled respectively to one of the plurality of second input/output ports and each of the plurality of modem devices also being coupled to one of a plurality of power lines, capable of communicating information to and from the second data source connection.

Claims (12)

1. A method for converting a plurality of powerlines in at least a building structure into a communication network for a plurality of users, the method comprising:

coupling an apparatus for communicating between a data source and at least one of a plurality of users through a powerline network, the apparatus comprising:

a datasource connection, the datasource connection coupled to a data source;

a powerline device coupled to the datasource connection, the powerline device being adapted to receive and transmit information in a first format from the datasource connection and adapted to receive and transmit information in a second format;

a virtual local area network device including a first input/output port and a plurality of second input/output ports, each of the second input/output ports numbered from 1 through N, where N is an integer greater than 1;

a plurality of modem devices coupled to the virtual local area network device, the plurality of modem devices numbered from 1 through N, each of the plurality of modem devices being coupled respectively to one of the plurality of second input/output ports, each of the plurality of modem devices also being coupled to one of a plurality of powerlines numbered from 1 through N, each of the plurality of powerlines being capable of communicating information to and from the data source;

allowing at least one of the users to communicate to the data source through one of the plurality of powerlines; and

denying access to at least one of the users from communicating to the data source through one of the plurality of powerlines.

2. The method of claim 1 wherein the building structure is an office building.

3. The method of claim 1 wherein the building structure is a residential home.

4. The method of claim 1 wherein the building structure is a multi-tenant building.
