摘要： A distributed radio system is disclosed. Transmit and receive packets of data are transported over a relatively high-speed multiplexed network, which in one embodiment may be an Ethernet network. The distributed radio system comprises in one embodiment a centrally-located network-level processing unit connected via network connections to one or more intermediate-level processing units. The intermediate-level processing units may be distributed throughout the coverage area. The processing units perform digital signal processing, as well as higher level processing such as signal routing, speech transcoding and proper interfacing to external environments, such as a macrocellular environment. Radio elements are provided that are accurately timed or synchronized, such that the radio elements have their own time base to ensure proper transmission, even when unpredictable network delays occur.

摘要： A system and method for delivering coupon messages to a consumer wireless device utilizes a fixed communication device that functions as a base station for the consumer wireless device. The fixed communication device has limited coverage zone. When the consumer wireless device comes within the coverage zone of the fixed communication device, the consumer wireless device selects the fixed communication device as the preferred base station. Upon completion of registration, the fixed communication device transmits one or more coupon messages to the consumer wireless device. The consumer may enter the associated retail establishment and complete a transaction using the received coupon message. The consumer wireless device may be viewed manually, or the display scanned or read electronically to accept the coupon message in the retail establishment.

摘要： A discrete multitone stacked-carrier spread spectrum communication method is based on frequency domain spreading including multiplication of a baseband signal by a set of superimposed, or stacked, complex sinusoid carrier waves. In a preferred embodiment, the spreading involves energizing the bins of a large Fast Fourier transform (FFT). This provides a considerable savings in computational complexity for moderate output FFT sizes. Point-to-multipoint and multipoint-to-multipoint (nodeless) network topologies are possible. A code-nulling method is included for interference cancellation and enhanced signal separation by exploiting the spectral diversity of the various sources. The basic method may be extended to include multielement antenna array nulling methods for interference cancellation and enhanced signal separation using spatial separation. Such methods permit directive and retrodirective transmission systems that adapt or can be adapted to the radio environment. Such systems are compatible with bandwidth-on-demand and higher-order modulation formats and use advanced adaptation algorithms. In a specific embodiment the spectral and spatial components of the adaptive weights are calculated in a unified operation based on the mathematical analogy between the spectral and spatial descriptions of the airlink.

摘要： A system and method for using a consumer wireless device in retail transactions utilizes a fixed communication device that functions as a base station for the consumer wireless device. The fixed communication device has a limited coverage zone. When a consumer wireless device comes within the coverage zone of the fixed communication device, the consumer wireless device selects the fixed communication device as the preferred base station and initiates a registration with that base station. The consumer wireless device is uniquely identified with ID data transmitted by the consumer wireless device to the fixed communication device. The unique identification is subsequently used in the process of completing a transaction.

摘要： The identity of a mobile communication device can be authenticated to allow the device to access a web site without the need for a user log-in operation. The mobile device stores an identity token and sends it to the web server in the web browser data stream. Additionally, the mobile device transmits an identity token to an authentication entity using a data stream other than the web browser data. The authentication entity queries the wireless network to verify authentication of the mobile device. The identity token may be the mobile telephone number itself, a temporary mobile subscriber identity assigned by the mobile network, or encrypted or hashed versions of either. Alternatively, a new temporary mobile subscriber identity may be sent to the mobile device and retransmitted back to the authentication entity.

摘要： A system to permit push-to-talk communications in an orthogonal frequency division multiplexed (OFDM) communication network. Individual wireless communication devices that are part of a Group Call are assigned the same set or sets of OFDM tones for a downlink timeslot. Because each wireless communication device receives the same set of tones, each device will receive a communication simultaneously. The assigned OFDM tones need not be contiguous within a block of available tones. Because a large number of OFDM tones are available, the concept may be extended to a large number of groups that each separately support a Group Call function.

摘要： An integrated communication system includes a satellite portion and a terrestrial portion. A plurality of timeslots are allocated for transmission and reception of data by the various components of the satellite portion and terrestrial portion. The allocation of timeslots to the satellite portion and the terrestrial portion may be predetermined or dynamically allocated based on traffic loads, time of day, day of week, and the like. Communication may be accomplished on a single frequency with the appropriate allocation of timeslots. The system includes delay compensation to accommodate signal processing delays and signal propagation delays. For example, a satellite may be instructed to terminate transmission prior to the end of its allocated timeslot to permit the signal from the satellite to propagate to its intended destination within the allocated timeslot to thereby avoid spillover into the next timeslot. This avoids interference between various elements of the communication system.

摘要： Client and server computers on a network can be authenticated using a shared secret. During a log-on and authentication process, the server transmits an image to the client. A mobile communication device captures and analyzes the image. If the image contains the shared secret, the mobile device can authenticate the server. The secret in the image can be a geometric relationship between elements of the picture, a mathematical relationship between elements, a particular number or types of elements in the picture, colors of elements, or combinations of the above. A single image may contain multiple shared secrets. The mobile device can readily analyze the image to determine if it contains the shared secret and thereby authenticate the server.
