Abstract: The invention relates to a combined near field communication and wireless power transmitter device comprising a first antenna coupled to antenna tuning network and capable of coupling to one or more second antennae in the near field of the first antenna with coupling characteristics, means for communicating wirelessly using said first antenna with a near field communication device in a near field communication mode, and means for transmitting wirelessly power using said first antenna to another device in the vicinity of the first antenna in a power transmission mode. In power transmission mode, the antenna tuning network operates in resonance and has an initial input impedance which is configured to change if there is a change in the coupling characteristics during power transmission, for example charging. The invention also relates to a method of transmitting power to a mobile device for example for charging purposes.

Abstract: A method, apparatus, system, and computer program for analyzing properties of an application-specific end-to-end communication connection are presented. In a connection performance analysis apparatus, measurement data messages are received from a plurality of traffic-monitoring nodes arranged at selected intermediate points in a plurality of network segments of the application-specific end-to-end communication connection and from at least one end node of the end-to-end communication connection, wherein a measurement data message comprises information related to a travel time of at least one data packet of the end-to-end communication connection to the traffic-monitoring node or to the end node transmitting the respective measurement data message. Then, the connection performance analysis apparatus analyzes the received measurement data messages in order to determine a bottleneck of the end-to-end communication connection.
