  • Publication number: 20140369329
    Abstract: Techniques for aggregating wireless communications are provided. These techniques include a method for aggregating wireless communications traffic in a femtocell. The method includes receiving at a femtocell a stream of data packets for a mobile device from a wireless router, selecting a transmission mode for sending data packets of the stream of data packets from the femtocell to the mobile device. The first transmission mode includes transmitting the data packets from the stream via a Long Term Evolution (LTE) interface of the femtocell. The second transmission mode includes transmitting the data packets from the stream via a WiFi interface of the wireless router. The third transmission mode includes transmitting a first portion of the data packets to the mobile device via the LTE interface and routing a second portion of the data packets to the wireless router for transmission to the mobile device via the WiFi interface.

  • Publication number: 20110116483
    Abstract: A server may be bypassed in the context of retransmitting data packets, when such data packets are missing or lost due to interference or some other network error. Decreased throughput and other disadvantages associated with data packet retransmission are avoided by negating the need to transmit retransmission request packets to the server and retransmitting a missing/lost data packet from the server. Instead, retransmission request packets may be sent to a router, and the router may respond by directly retransmitting the missing/lost data packet to the client, where prior to retransmitting the missing/lost data packet, it is determined whether the data packet is a Transport Control Protocol or User Datagram Protocol packet, and proceeding with the retransmitting only if the data packets is a Transport Control Protocol packet.
