Another form of Broadband over Powerline (BPL) is:
In-House BPL: a form of indoor PLC (Powerline Carrier) that operates over residential or business interior electrical cabling at 110/220 volts. Standards for in-house PLC are relatively recent, with the HomePlug standards perhaps being the most notable. HomePlug 1.0 was published in 2001 by the HomePlug Powerline Alliance (http://www.homeplug.org/), which was founded by vendors including Cisco and Intel. Those standards are loosely based on Ethernet and support up to 16 devices communicating at speeds up to 14 Mbps over a shared electrical path. HomePlug compatible devices (e.g., include Pcs, routers and bridges that use Ethernet, USB or Wi-Fi technologies) can simply plug into an electrical socket through a bridge or adapter about the size of a typical voltage adapter and, thereby, connect directly to the LV wiring. So every electrical socket effectively becomes a port into a high speed LAN. In-House BPL speeds don’t compare well with more conventional Ethernet LANs, but can be an attractive solution where buildings can’t easily be rewired and where a building’s physical layout is not conducive to wireless LANs. The next step is the HomePlug AV standard, which is being built from the group up to support entertainment applications such as HDTV and Home Theater. HomePlug AV will run at speeds up to 200 Mbps. Dozens of HomePlug 1.0 compatible products have been certified and many more are under development. In a home a BPL modem plugs into a wall outlet inside the house, receives those signals from the outside power lines and typically converts them into a familiar 802.11b Ethernet connection.
