Abstract: A method for determining a location of a client device in a wireless network including the client device and at least three network devices, each of the three network devices having a known location comprises a pairwise exchanges of messages between at least three different pairs of network devices of said at least three network devices. In the pairwise exchange messages, wherein in a pairwise message exchange time difference information of the time difference between reception of a message and subsequent transmission of a message is included. This time difference information is used in the determination of the location of the client device.

Abstract: In a MIMO communications system a first communications device applies beamforming to a complete transmission packet including both synchronization data and either payload data or training symbols. A second communications device evaluates the beamformed synchronization data and determines and transmits a feedback information indicating minimum required synchronization data and/or a minimum number of training symbols. The first communications device tailors the synchronization data and/or number of training symbols on the basis of the feedback information. Beamforming the complete transmission packet facilitates signal suppression at defined locations. When the channel properties change, the second communications device may provide further channel state information to adapt beamforming in the first communications device without transmission of not beamformed training symbols. The communications system may be a powerline telecommunications system.
