    摘要: Monitoring device modules (10) in containers on a ship are polled by a tracking proxy (12). Monitoring data is thus captured, and the proxy 12 can ascertain in real time that the correct group of containers is present. The proxy (12) also transmits higher-value report messages with relatively low bandwidth via a satellite communication system (13) to a gateway (15). The gateway (15) routes the messages on to various systems such as tracking centers. Also, the gateway (15) regularly polls and authenticates the distributed tracking proxies (12) within its group.

    摘要: A mobile network comprises remote base transceiver station (BTS) nodes (3, 4) linked with a central base station controller (BSC) node (9). The latter is in turn linked with a mobile switching centre (MSC, 10), a visitor location register (VLR, 11), and a home location register (HLR, 8). Mobile stations (2, MS-A, MS-B, and MS-C) are located in the cells of the BTSs (3, 4). The remote nodes (3, 4, 3(a), 4(a)) are connected to the central node BSC (9) over a remote backhaul satellite connection. Calls are routed locally while the central nodes continue to manage calls and services from central feature-rich and typically more reliable switches of a core network. This means that calls set up between subscribers on the same remote node get connected within the remote node but call supervision is still carried out by the central nodes. The features and services of the existing core network are preserved. For example, if the calling subscriber is a pre-paid GSM subscriber and their account runs out during the call a release signal will still be sent from the central node to the remote even though the voice traffic is being handled by the remote node.

    摘要: A method for configuring a multiple input multiple output (MIMO) wireless communication begins by generating a first preamble for a first antenna of the MIMO communication, wherein the first preamble includes a carrier detect field, a first channel select field, a first signal field, and a second signal field. The method continues by generating a second preamble for at least one other antenna of the MIMO communication, wherein the second preamble includes the carrier detect field, a plurality of channel select fields, and the second signal field. The method continues by simultaneously transmitting the carrier detect field via the first antenna and the least one other antenna. The method continues by transmitting the first channel select field and the first signal field via the first antenna. The method continues by, subsequent to the transmitting the first channel select field and the first signal field via the first antenna, transmitting the plurality of channel select fields via the at least one other antenna. The method continues by simultaneously transmitting the second signal field via the first antenna and the at least one other antenna.
