A networked computing system for optimizing network channel resources. The system includes a sender device, user equipment, a congestion sensing agent, a data transfer agent, and a data communications network facilitating data communications amongst all devices of the system. The networked computing system is configured to detect a portion of channel traffic that is associated with a first data type, detect a portion of the channel traffic that is associated with a second data type, and determine whether to modify at least one data transfer of the second data type based on a comparison of the portions of the channel traffic associated with the first data type and the second data type. The first data type may relate to either voice data communications or another high priority data type, and the second data type may relate to a media content file type.

A communication system is disclosed that allows high data-rate transmission of data between components. N-bit parallel data is transmitted in K-frequency separated channels on the transmission medium so as to fully take advantage of the overall bandwidth of the transmission medium. As a result, a very high data-rate transmission can be accomplished with low data-bit transmission on individual channels. A transmitter system and a receiver system are described for the communication system.

Method for radio communication in a wireless local area network and transceiving device refers to wireless local area networks (WLAN) consisting of a multitude of transceiving devices of users (14, 15, 16 . . . N). Simultaneous scanning by their antenna beams in different directions by the transceiving devices (with the transceiving devices being in reception mode) and transmission of an omnidirectional signal in the form of calibration signal and data package by one of the transceiving devices of the network (with the transceiving device being in transmission mode), reception of the signal by the transceiving devices operating in reception mode and subsequent orientation of their antenna beams in the direction of signal source. The recognition and orientation is performed during the period of reception of the calibration signal. The Method increases the range of a WLAN, reduces the transmission time and improves quality and reliability of communication. Each transceiving device (1) includes at least one directional antenna (3) featuring a controllable directional pattern, switched-over by unit (4), reception / transmission mode switch (5), receiver (8), transmitter (10) and controller (11). Additionally a unit for signal detection (13) is incorporated in the device.

The invention refers to wireless local area networks (WLAN) consisting of a multitude of transceivers capable of establishing communication with one another (i.e. operating in a peer-to-peer mode) under the control of network coordinator (the so-called “ad hoc” networks). Implies the assignment of the role of the temporary coordinator to a transceiver from among the plurality of transceivers, switching-over other transceivers into the mode of a network client, orientation of antenna beam of a transceiver (switched-over into the client mode) equipped with a direction-agile antenna in the direction of the temporary coordinator of the network and transmission of information to an addressee by a client-transceiver of this network that has got the permission to transmit from the temporary coordinator. A WLAN comprises a multitude of transceivers, one of which serves as a temporary coordinator for said network and at least two of which have a direction-agile antenna and means for the operation of said antenna in the omnidirectional mode, in the directional scanning mode or in the stationary directional mode, an identification means responsive to transmission of a signal, including the transmission of a synchronization signal or identification signal intended for orienting said antenna in the direction of said signal being transmitted. The invention improves the quality and reliability of communication for WLAN users (including mobile users) thus increasing the data transfer rate.

The present invention relates to an arrangement and a method for providing user station with access to (a) service providing network(s). It comprises a radio access network control node (RANCN) (3) acting as a gateway node between WLAN access points (AP) (2A,2B;4) and the service providing network, and it comprises connection processing means for adapting service providing network transport protocols such that a WLAN supporting user station (1A,1B;1) can access the service providing network services over the WLAN radio interface.

A plurality of sets of circuits are provided, each of which generates an impedance code through the use of an impedance control circuit in association with a resistive element connected to an external terminal, and each of which varies the impedance in accordance with such an impedance code. The impedance control circuit includes an impedance comparator which is formed equivalently to the resistive element and the plurality of sets of circuits, and which performs an impedance comparison with each of a plurality of replica circuits to form an up signal that increases the impedance and a down signal that decreases the impedance. Counters are provided adjacent to the individuals of the plurality of sets of circuits to thereby generate the impedance codes in response to the up signal and the down signal.

A method for allocating information transfer capacity in a mobile communication system, and a mobile communication system are provided. In the method according to the invention, the information transfer capacity is allocated to the user by forming a high capacity service site inside a cell of a base station by using a remote unit of a base station. The invention enables allocation of capacity to a specific mobile station with a low cost of multi-user interference generated to other receivers in the cell.
