摘要： An active antenna device, a network device, an access point equipped with the network device and a plurality of distributed active antenna devices form components of a communication system. The active antenna device contains an antenna unit, an amplifier unit and a control unit, wherein the amplification of the amplifier unit is controlled by the control unit according to an instruction from a management unit located in the network device. The devices achieve a low handover frequency whereas rendering the communication less vulnerable to contentions and/or interference than in the conventional systems.

摘要： Exemplary embodiments of method, gateway, client, software arrangement and computer-accessible medium are provided for a handover of a client from a local network to an access network. For example, information can be received from the client regarding the client's ability to connect directly to the access network, whereas the client is connected to a local network. A request for the handover of the client and an identification information of the client can be transmitted to the access network. Further, the handover of the client can be initiated from the local network to the access network.

摘要： A communication method in an automation system, wherein the system comprises an access point and client terminals that receive downlink data sent from the access point and send uplink data to the access point, and the data transmission is divided into a master multiple receiver aggregation phase and more than one slave multiple receiver aggregation phases. During the master multiple receiver aggregation phase, the access point aggregates the data to be sent to the plurality of client terminals into one packet for transmitting in the downlink, and during the slave multiple receiver aggregation phases, the access point aggregates data in which errors have occurred when being transmitted during the master multiple receiver aggregation phase into one packet for transmitting in the downlink. The method can have strict control, through the access point and over the uplink and downlink data transmission, thus enhancing the certainty during automation communication and further reducing the cycle time.

摘要： A load balancing method for a wireless communication system, which has a backbone network, more than one Access Point connected to the backbone network and more than one client. In the method, the client transmits a Probe Request message to the more than one Access Point; the Access Point monitors its load. If the Access Point is under an overload situation, it transmits a Probe Response message to the client by the minimum transmitting power. If the Access Point is under normal load situation, it transmits a Probe Response message to the client by normal transmitting power. The client preferentially chooses the Access Point under normal load situation to access based on the signal strength of the received Probe Respond message. The method thus provides the client with a priority of the Access Points, wherein the Access Point under an overload situation has a lower priority.

摘要翻译： 一种无线通信系统的负载平衡方法，具有骨干网，多个接入点连接到骨干网和多个客户端。 在该方法中，客户端向多个接入点发送探测请求消息; 接入点监视其负载。 如果接入点处于过载状态，则以最小发射功率向客户端发送探测响应消息。 如果接入点处于正常负载情况，则通过正常的发送功率向客户端发送探测响应消息。 客户端在正常负载情况下优先选择接入点，以根据接收到的探测响应消息的信号强度进行访问。 因此，该方法向客户端提供接入点的优先级，其中在过载情况下的接入点具有较低的优先级。
