Abstract: A wireless antenna system for a terminal comprises an antenna structure and frontend ports for connecting to transmit and/or receive circuitry of the terminal. The antenna system is operable in a first radiation mode and a second radiation mode, wherein the modes are orthogonal. The circuitry is arranged to map the first feed port to the antenna structure for the first radiation mode across a first frequency band having a bandwidth which covers one of an uplink frequency band and a downlink frequency band of the transmit/receive circuitry. The circuitry is arranged to map the second feed port to the antenna structure for the second radiation mode across a second frequency band, wherein the second frequency band covers both of an uplink frequency band of the transmit/receive circuitry and a downlink frequency band of the transmit/receive circuitry. The above concepts are extendible to more than two modes.

Abstract: The invention relates to a method for secure operation of a plurality of devices, the devices suited for use in such method and the entire arrangement of such devices, and further computer program products and related machine readable signal storage media, governing said method or parts thereof, executed on or for configuring to prepare for execution on one or more of said devices, particularly the invention provides for authorization and permissions when logging into and off from a computer network from a computing device. The methods comprise of when executing a logoff procedure, storing the secret information on a second server by use of first credentials generated by a first server and when executing a logon procedure retrieving the secret information from the server by use of second credentials generated by a first server.

Abstract: A wireless device has receiver circuits and/or transmitter circuits supporting at least two simultaneous independent transmit paths in the same frequency band, and a multiport antenna with N ports, for the available receiver or transmitter circuits. The multiport antenna has a compact mechanical state and an extended mechanical state, and is connected to the N ports of the receiver and/or transmitter circuits by a 2N-port matching and decoupling network. This has multiple, selectable electrical states, each corresponding to at least one of the mechanical states. One combination of the mechanical state and the electrical state allows operation in a wireless channel of rank N. A second combination of the mechanical state and the electrical state allows operation in a wireless channel of rank less than N. Better MIMO performance with the extended antenna configuration can be obtained with the convenience of retaining limited performance when the user cannot use the extended antenna.

Abstract: Transmitter for distributing data signals, characterised in that it is provided with receiving means for collecting one or several data signals, a control unit (5) and a transmitting unit (3) connected thereto for transmitting an above-mentioned data signal via a network to one or several addressable receivers (6) from a series of pre-selected users, after the above-mentioned control unit (5) has received a starting signal to this end.
