The ARRIS GCA2002 Extender uses existing coax cables to securely deliver gigabit data around the home, or small business, using the G.hn Wave 2 standard as specified by the HomeGrid™ Forum. These G.hn bridges connect to a single Coax Cable outlet in the home and has a Gigabit Ethernet port to connect a PC, game console or other Ethernet connected device. Up to 16 devices may be connected as a single home network.

The extender plugs directly into the mains power supply; there is no external power supply to manage. Each G.hn Bridge includes a TR-069 client for link metric monitoring as well as diagnostics and configuration by a remote Access Control Server.
