Patent number: 8526418Abstract: A media access control (MAC) controller is disclosed for a network providing communication for network stations located at a plurality of customer premises and sharing a communication medium, each of the premises having a plurality of network stations. The MAC controller includes a virtual local area network (vLAN) controller, providing access to the communication medium for and communication among the stations located at a single customer's premises, to define a vLAN between them. A group local area network (gLAN) controller provides access to the communication medium for and communication among interfering vLANs, two vLANs being considered to be interfering when one can sense communications over the medium from a station in the other. A MAC controller is provided in at least one station in a vLAN.Type: GrantFiled: July 7, 2008Date of Patent: September 3, 2013Assignee: RPX CorporationInventors: Michael B. Propp, David L. Propp, Khaled Saab, Du Thi Do, John Jakson

Patent number: 8198998Abstract: The location of a device on an electrical power line is identified using a power line characteristic, such as a power line impedance as a function of frequency, and/or a power line transfer function identified from the first device to a second device communicating with the first device over the electrical power line. Power line information is determined by receiving a signal from a first device, determining a power line transfer function based on the received signal, and determining power line information based on the determined power line transfer function.Type: GrantFiled: January 23, 2009Date of Patent: June 12, 2012Assignee: Adaptive Networks, Inc.Inventors: Michael B. Propp, David L. Propp, Khaled Saab, Donald Orrell

Patent number: 8040966Abstract: This disclosure relates to varying load and modulation applied to each of multiple frequency subchannels based on anticipated attenuation experienced by those subchannels. Communicating data includes identifying a static component of a transmission medium for wideband communications having at least two subchannels determining a function of noise is attenuation versus frequency for the static component selecting wideband modulation schemes for the subchannels based on the function determined and communicating a data signal over the subchannels. The transmission medium includes a medium other than a copper telephone wire between and including a carrier facility and a termination of the copper telephone wire at an access point at a user premise and copper telephone wire in a cable riser in multitenant units and multi-dwelling buildings. Independent demodulation functions may be applied to at least two of the subchannels.Type: GrantFiled: December 29, 2010Date of Patent: October 18, 2011Assignee: Ceres Communications Technologies, LLCInventors: Michael B. Propp, Khaled Saab
