  • ACTIVE ANTENNA DEVICE, NETWORK DEVICE AND ACCESS POINT OF A WIRELESS NETWORK
    Publication number: 20110269404
    Abstract: 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.

  • METHOD, GATEWAY, CLIENT, SOFTWARE ARRANGEMENT AND COMPUTER-ACCESSIBLE MEDIUM FOR FACILITATING A HANDOVER BETWEEN A WIRELESS LAN AND A RADIO ACCESS NETWORK
    Publication number: 20090164610
    Abstract: 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.
