摘要： A wireless telephony network provides satellite radio program information and content, in addition to conventional wireless telephony services, to eligible mobile stations of the wireless telephony network. The wireless telephony network receives satellite radio programming from a satellite radio service network, establishes one or more bearer channels (e.g., conventional voice channels or higher-bandwidth data links) and sends the programming to the one or more mobile stations via the one or more bearer channels. The wireless telephony network monitors and obtains billing information associated with integrated service delivery and coordinates the billing information with a satellite radio service provider. A controlling provider may be selected to control billing for the integrated services such that the customer receives a single statement.

摘要： A system and method for monitoring the quality of signals transmitted to a remote service area that is located outside of the broadcast area of a main broadcast site. The present invention converts and combines the signals that are to be broadcast from the main broadcast site to a satellite for redistribution to the remote service areas. The converted and combined signals are looped back to a network monitoring operations located at the main broadcast site before being transmitted to the satellite. In another embodiment, the remote broadcast sites send signal strength measurements to the network monitoring operations to provide an indication of satellite transmission problems not related to the quality of the signal being broadcast from the main broadcast site.

摘要： An apparatus and method integrates cellular technology, global positioning system (GPS) technology and satellite radio technology. The components of the apparatus share resources, such as a power, dual GPS/satellite antennae, display screen and controls. The system provides an “on-demand” back channel, such as via the nationwide cellular phone network, that allows a satellite radio subscriber to order data on demand from the satellite radio provider, such as a particular list of songs or travel information. The invention utilizes the existing satellite radio infrastructure which is capable of delivering large amounts of streaming on-demand customized programming and information across a satellite channel to a subscriber's satellite radio decoder. By effectively utilizing the growth and momentum of satellite radio technology, the invention introduces new options for location based services (LBS). Using the existing satellite radio infrastructure minimizes the overall cost of delivery of location based services while allowing a wide range of service options.

摘要： A bi-static communication relay includes a receiver and transmitter carried by different platforms. In particular, the transmitter may be carried by a geosynchronous satellite forming a broadcast platform. The receiver is hidden on a low observable platform, such as an airborne or even a ground based platform forming a hidden platform. The location of the low observable platform is known only to legitimate users of the system. Communications between the hidden platform and broadcast platform are by way of a secure narrow beam uplink to reduce the risk of jamming. Physical separation of the receiver and transmitter essentially defeats the jammer's high power amplifier advantage since the receiver platform is hidden from the jammer. This forces the jammer to use a low gain antenna in order to cover as much sky as possible. System users, on the other hand, can use the gain advantage of a directional antenna, since they alone have knowledge of the hidden platform's location.

摘要： A broadcast/narrowcast dual mode satellite is capable of selectively providing narrowcast operations or broadcast operations. The dual-mode satellite includes a broadcast/narrowcast dual-mode receiving system that receives from one or more terrestrial transmitting stations one or more communication uplink signals that selectively correspond to one or more narrowcast communication signals or one or more broadcast communication signals. Narrowcast communication signals are typically distinct from each other and are directed to one or more narrowcast geographic cells. Broadcast communication signals are directed to one or more broadcast regions, each of which encompasses plural narrowcast geographic cells. The dual-mode satellite also includes a broadcast/narrowcast dual-mode transmitting system that transmits one or more communication downlink signals that selectively correspond to broadcast communication signals and narrowcast communication signals received by the receiving system. Dual-mode satellite is capable of operating in the narrowcast mode or the broadcast mode, either separately or simultaneously together.

摘要： A hybrid carrier frequency offset estimator that uses data-aided and non-data-aided signal processing techniques to produce multiple candidates for the carrier frequency offset within a return channel receiver in a DVB-RCS system using turbo coding and quadrature phase shift keying (QPSK) data modulation. In this system, the invention is employed to estimate signal distortion caused by carrier frequency offset so that this particular source of signal distortion can be removed to improve the ability of the receiver to maintain synchronization in low signal-to-noise conditions. This, in turn, allows the receiver to meet the DVB-RCS performance target, measured in terms of packet loss ratio, in low signal-to-noise ratio conditions and in particular for burst-mode data transmission with a short data packet size.

摘要： A DBS distribution network (100, 90) is modified with a secondary transmission bi-directional capability below 950 MHz by adding filters to separate modified mobile-communications (60) frequencies from typical DBS services. DBS subscriber termination points function as extremely localized ultra-miniature cell sites within a building. Third generation (3G) cellular networks and second-generation (2G) cellular networks are together merged with DBS networks. The modified network simultaneously handles traffic in known and future cellular air interface standards such as: UMTS, GSM, TDMA, CDMA. Cellular mobile radio terminals do not have to be modified. Signals traverse on non-utilized DBS frequencies. DBS active elements are modified, and new components are provided.

摘要： A join process is disclosed for a wireless mesh topology network. In the network, nodes have multiple spatial coverage sub-sectors together covering a larger sector angle and a node can establish connection with other nodes located in directions covered by its sub-sectors. The join process adds a joining node to the network and includes having the joining node listen to sub-sectors at a specific receiving frequency for a defined time. Thereafter, the network node changes its sub sectors and its receiving frequencies according to a defined timing and sequence. Active network nodes transmit organized invitation data packets on defined sectors, frequencies and timing, based on relative location and relative angle orientation deduced from sub-sectors already in use for existing internal network communication. This reduces frequency interference in the network and reduces time required for the join process.
