A device for communicating digital data over power lines includes a power line interface for transmitting data over at least one band of frequencies. An orthogonal frequency division multiplexing (OFDM) modulation unit generates OFDM symbols using a set of tones for the frequency band. A preamble generation unit generates preamble sequences for the frequency band by using the set of tones used by the OFDM modulation unit. The tones used by the preamble generation unit have a constant magnitude, and a set of phases obtained by quantizing to a small alphabet the phase of a set of tones obtained by taking an IFFT of a portion of a preamble used by a non-interoperable powerline access device. The device may transmit on two or more bands using a sampling frequency clock, wherein a lower band clock frequency is equal to or an integer divisor of a higher band clock frequency.

Central coordinator and proxy coordinator information typically found in powerline communications standards, such as the HomePlug standards, is used to ensure proper communication of a data packet directed toward an unknown destination. By using the central coordinator nodes and the proxy coordinator nodes to repeat the data packet according to a set of forwarding rules, the data packet can be transmitted to each node in the network using a tree topology that avoids generating loops that may result in packet storms. When the destination node is located, subsequent data packets can be sent to the destination node through a known route.

Convergent network topology discovery and mapping. A topology discovery protocol allows for the discovery of the different respective communication links within a convergent network that may become composed of any of a number of different respective network types (e.g., a local area network (LAN), wireless LAN (WLAN/WiFi), a multimedia over coax alliance (MoCA) network, a HomePlug network, and a wireless point to point (P2P) system, etc.). Such a topology discovery protocol may be implemented as a Layer 2 peer-to-peer link layer discovery protocol (LLDP).
