The France Telecom research entity Orange Labs has 18 locations on three continents. Within the Orange Labs a specific team is in charge, since 1994, of studies relative to wave human interaction. This team has developed numerical and experimental tools to assess the exposure of human exposed to electromagnetic field. It is in close collaboration with Telecom institute in the WHIST Lab (common laboratory of France Telecom Orange Labs RD and Telecom Institute In a specific program, Orange Labs is also focusing on heterogeneous networks complementarities, network selection and service continuity both from architectures, proof of concept and standardisation perspectives
