Executive Overview

The GefenTV Ethernet over PLC Extender offers consumers one of the easiest, most convenient methods of Ethernet distribution available today. Users can access the Internet from any room in the house without rewiring or running new cables. Instead, they simply tap into their existing, in-wall power line cables to extend up to four Ethernet connections throughout their home or office. A DSL, cable or satellite Ethernet signal is distributed throughout the home using small sender and receiver units equipped with Ethernet RJ-45 ports that transmit data up to 200 Mbps to guarantee a rapid data delivery.

The ability to utilize the power lines in the walls of your home or office to access the Internet saves money on cabling costs while improving the installation process. No additional cables are needed to connect the GefenTV Ethernet over PLC sender unit to the receiver, which can be placed up to 1000-feet (300m) apart.

The solution is designed for simplicity. The sender unit connects your active DSL, cable or satellite Ethernet router into any standard wall-jack power outlet. The receiver unit is connected to the power outlet in another room where you'll be working.  Once both units are powered, four Ethernet ports on the receiver unit will be active.

All 10/100BASE-T Ethernet protocols are passed through the GefenTV Ethernet over PLC Extender at speeds up to 200 Mbps making it perform better than some of today's wi-fi systems. Built-in security codes protect the system.

Gefen also supplies a GefenTV Ethernet over Coax solution, which allows users to connect their sender and receiver units to a home's existing coaxial cable to distribute the Internet to any room. The sender unit links the Ethernet signal to the in-wall cable infrastructure using a coaxial port, while the receiver delivers four active Internet connections to any other room in the same building. Either of the solutions will run you about $200. Basically, if you have cables in your walls, you don't have to ever worry about additional Ethernet wire runs ever again. Gooo team GEFEN!

200Mb Ethernet over powerline has been around for years.

Ethernet over coax has been around for years too. It is most commonly used in Verizon FIOS installs. Check out the Motorola NIM100.

These may be rebranded products from other vendors.
