Universal powerline bus (or UPB) is a protocol for communication among devices used for home automation. It uses power line wiring for signaling and control.
UPB was developed by PCS Powerline Systems of Northridge, California and released in 1999. Based on the concept of the ubiquitous X10 standard, UPB has an improved transmission rate and higher reliability. While X10 without specialty firewalls has a reported reliability of 70-80%, UPB reportedly has a reliability of more than 99%.

Famous quotes containing the words universal and/or bus:
“The axioms of physics translate the laws of ethics. Thus, “the whole is greater than its part;” “reaction is equal to action;” “the smallest weight may be made to lift the greatest, the difference of weight being compensated by time;” and many the like propositions, which have an ethical as well as physical sense. These propositions have a much more extensive and universal sense when applied to human life, than when confined to technical use.”
—Ralph Waldo Emerson (1803–1882)
“In the dime stores and bus stations,
People talk of situations,
Read books, repeat quotations,
Draw conclusions on the wall.”
—Bob Dylan [Robert Allen Zimmerman] (b. 1941)
