摘要： Handoff of (i) a mobile wirelessly communicating device—a mobile—between (ii) as plurality of stationary base stations within cells within a domain of (iii) a stationary gateway router all within (iv) a communications network based on the Internet Protocol (IP) is without interchange of control and responsive to the mobile, only. The gateway router assigns to the mobile at a time before the handoff IP addresses suitable for the mobile to connect to the gateway router through all the plurality of base stations of the domain. Unilaterally deriving a handoff decision to switch base stations, the mobile directs its wireless communications link to a new base station where signal level registration is performed. Responsive to a link layer trigger at the new base station, the gateway router is informed of the handoff, and both the router and the mobile independently construct the mobile's new IP address.

摘要： The present invention relates to a wideband communication network using wireless radio transmissions either on a stand-alone basis or to supplement a hard-wired network. The exemplary network comprises (a) a plurality of transceivers associated with separate users of the network; (b) optionally at least one concentrator associated with certain separate subgroups of wireless and possibly hard-wired transceivers for providing duplex operation; and (c) a central node (i) capable of providing both duplex communications directly via a radio channel using radio links with certain subgroups of the transceivers and via a hard-wired connection with each optional concentrator, and (ii) for polling the needs of all transceivers and directing all packets of information from active transceivers through the central node and to the destined transceivers during each frame period. The network also preferably includes diversity and resource sharing techniques to provide added protection against channel impairments on an as-needed basis.

摘要： A digital communications satellite (12,44) receives signals from a plurality of narrow input spot-beams (14) of an uplink. It regenerates, multiplexes and routes the signals for transmission in a plurality of narrow output spot-beams (42) of a downlink. The uplink beams (14) each include a plurality of frequency re-use channels (18), while the downlink beams (42) each have only a single wide-band channel. The satellite (12,44) may multiplex the signals either before or after routing them. The spot-beams (14,42) may be fixed or scanning.

摘要： A system and method for producing an eye safe laser communication system. The system and method detects an interfering object in the optical path and cuts off or reduces the power in the communication beam to safe levels. In one embodiment, a second laser diode transmitter and receiver is installed in each network node. The laser transmitter is pointed at a corresponding network node and the pulses travel in parallel with the communication beam. The pulses are reflected back to the transmitting node where they are detected. Their flight time is measured. When an interfering object is present, in one scenario, the pulses bounce of the interfering object and return to the receiver in the transmitting node, resulting in a reduced flight time. This reduced flight time is interpreted as an interfering object and the beam is shut down or reduced to a safe level. In a second scenario, the interfering object absorbs the detection beam. In another embodiment, a CCD camera is used to capture a reflection from an object in the path of the communication link. In this embodiment the CCD has an overlapping field of view with the communication transceiver's transmit laser. The laser's transmission beam forms a baseline pattern on the CCD. Any pixel to pixel variation from the baseline pattern indicates an interference, thus triggering the system to shut down or reduce the power of the communication link. Another embodiment uses retroreflection of the human eye to detect interference by the human eye and an optical magnification device. In this embodiment, a CCD is used to detect signals bent back by retroreflection of the human eye. When such a signal is detected, the link is immediately shut down. Another embodiment utilizes the communication link itself and a detector in the receiver to detect instantaneous power drops caused by an interfering object. When an interfering object is detected, the system shuts down or reduces the power of the communication beam to an eye safe level.

摘要： Diverse communication terminals attach via broadband radio to a communications network at any of typically three hierarchical cell sizes increasing from, typically, a single building to a city to a region. Almost all telecommunications traffic transpires, however, within lowest-level “picocells 1” to and from low cost “base stations 11” that have typically one radio transceiver 111, four optical transceivers 112, an ATM switch 113 and an ATM controller 114. Each local “base station 11” is interconnected to a regional “end office switch 12”, where is realized connection to a worldwide wire/fiber line communications backbone 4, upon a multi-hop mesh network 100 via short highly-focused free-space broadband directional optical links 10. By this free-space wireless broadband access the need for new broadband access cabling the “last mile” to subscriber/users is totally surmounted. Subscriber service is of the order of 20 Mb/s peak rate, and 10 Mb/s average rate.

摘要： A transmitted high definition television signal is represented by a packetized datastream configured as a sequence of data fields with a non-uniform data rate due to different types of different duration non-data overhead information. Each data field is prefaced by a Field Sync overhead segment followed by 312 packetized data segments each with associated overhead information. At a transmitter, a transport processor forms data packets with associated headers and exhibits uninterrupted operation at a constant uniform data rate, while supplying a packetized datastream to a network which constructs sequential data fields by inserting the non-data overhead information into the datastream. The transport processor is advantageously operated at a constant uniform data rate without having to modify the original data field structure to accommodate the needs of the data field construction network. This result is facilitated by transferring data from the transport processor to an associated interface/buffer network in response to a 3/8 symbol clock, in combination with a predetermined buffer fullness level. A counterpart transport processor/decoder at a receiver coacts with a data field processor and similarly exhibits uninterrupted operation at a constant uniform data rate.

摘要： In a digital television signal processing system, a special codeword, a Packet Alignment Flag (PAF (14), is inserted into an MPEG codeword bitstream to signify the presence of a Group of Pictures (GOP). The PAF immediately precedes a Picture Start codeword for an "I" frame, which initiates a GOP. A data packet (12) under construction when a PAF (14) appears is terminated since a GOP is intended to begin at a packet boundary. Such termination may result in an abbreviated packet of less than a prescribed number of codewords needed to complete a data packet. The last word of each packet is designated as such to facilitate the subsequent combining of data packets (12) with respective headers (18). An incomplete data packet is filled with null (zeroed bits) words to make up a complete data packet with a prescribed number of words.
