    摘要: The invention discloses a method for use in a wireless communications system with a plurality of broadcasting nodes, comprising the step of enabling one node in the system to function as a central node in said system and letting said node enable measurements on at least one frequency in a frequency band used by the system. Said measurements are carried out to detect if said at least one frequency is being utilized by a transmitter foreign to the system. Preferably, the measurement is enabled by means of the node transmitting a message to other nodes in the system, said message being a message pre-defined within the system as a message prohibiting all nodes from transmitting during a certain interval, said message being transmitted after the system has been detected by the node to be silent during a predefined interval between frame transmissions from the nodes in the system.

    摘要: A wireless station, in a wireless LAN, includes a network interface to a network interface device, e.g., a NIC, that includes a transceiver, an antenna, at least a first power supply or energy holder. The wireless station supports transmission of data in frames of variable length. Frame fragmentation is implemented by dividing a (long) frame into a number of frame fragments. Each fragment is sent as a non-fragmented frame. The length of a time period before or between transmission of (consecutive) frame fragments is controlled in order to decrease energy consumption during a predetermined time interval.

    摘要: Embodiments of the present invention include a method and system for operating a dual mode terminal that includes a wireless local area network interface and a cellular radio interface. According to an embodiment, the dual mode terminal camps on the cellular radio interface when idle. When a Page Request message is received over the cellular radio interface, the terminal determines whether wireless local area network coverage is possible from an access point providing wireless local area network cellular communication. If so, the terminal processes the incoming communication request over the wireless local area network towards another party, wherein then the communication is ended, the terminal goes back to camp on the cellular channel.
