[Via Satellite 11-19-2015] Wireless link optimization specialist XipLink has completed a test with a significant Asian cellular service provider, delivering accelerated voice, data and video traffic exceeding 90 megabits per second (Mbps) to a remote LTE base station over a satellite connection.

Jack Waters, CEO of XipLink, told Via Satellite the test always achieved 100 Mbps or more on a 97 Mbps link (90 Mbps downstream, 7 Mbps upstream), and that the actual throughput in this test was 155 Mbps.

The demonstration showed XipLink’s high speed Transmission Control Protocol (TCP) acceleration capability, and used several optimization features. The company’s streaming compression technology reduced text traffic from 90 Mbps to 14 Mbps, an 84 percent decrease, and its XipLink Real-Time (XRT) feature reduced the bandwidth of voice traffic 40 percent using header compression. The test also achieved a 90 percent gain in packet per second throughput rates using coalescing techniques.

Through XipLink’s satellite-centric flow control, packet loss was also reduced to 0.1 percent, which has the effect of higher throughput on the link due to no retransmissions. The Asian cellular service provider is an existing XipLink account that has traditionally used XipOS for Wi-Fi aggregation and backhaul with excellent results. The addition of GTP tunnel acceleration to XipOS was required to meet LTE standards for transmitting cellular TCP traffic over the S1 link while also optimizing non-TCP traffic such as User Datagram Protocol (UDP).
