IS-2005-05: Open Systems for Homes and Buildings: Comparing LonWorks and KNX
This white paper from i&i Limited traces the origins of LonWorks from Echelon Corporation and European Installation Bus (EIB) - now the mainstay of Konnex (KNX) - originally developed by Siemens. The paper examines their impact in one particular market: home and building electronic systems. Both systems support communications over twisted-pair wiring and power line carrier, but with different data rates. The scope of the study is limited to the application area of KNX: LonWorks is used in a much wider range of applications. The standards and trade association activities of both groups are discussed.
