摘要： A method for optimally serving Stations (STA) on Wireless Local Area Network (LAN) using a Controlled Contention/Resource Reservation protocol of the IEEE 802.11e standard. The Wireless LAN includes multiple STAs, mobile or Stationary, airlinked to an access point as a Basic Service Set (BSS). A Hybrid Coordinator (HC) is co-located with the access point for allocating the bandwidth for the BSS using a Controlled Contention/Resource Reservation protocol defined in the IEEE Standard 802.11(e). The HC transmits Contention Control (CC) frames and initiates Controlled Contention Intervals (CCI) having a selected number of slotted intervals. HC receives Resource Reservations (RR) detailing bandwidth needs from STA contenders during a specified time interval called the Controlled Contention Interval (CCI.). Several parameters are installed in each CC for contention control purpose. The several parameters are controlled to optimize efficient use of the wireless medium and reduce access delays for RR frames contending for the wireless medium.

摘要： An 802.11 source station transmits a signal with the duration field other than that required for the transmission to prevent transmission by other stations during known sequences. Thus, the source station uses the duration field to spoof the actual time the medium will be occupied, to stations within range of the signal. A station within range of the transmitted signal will check the duration field of the transmitted signal, and update the station's network allocation vector. Thus, the station will not transmit because the station's network allocation vector indicates that the medium is in use, even though the station maybe unable to hear the carrier. Accordingly, spoofed stations may, for example, 1) delay transmission until a more critical transmission has completed, 2) allow unknown or foreign protocol to have preferential use of the medium, 3) prevent interference from hidden stations, and 4) allow sharing of the medium by overlapping basic service sets.

摘要： In an environment of competing satellite systems having in part shared bands/channel frequencies and at least one system having non-interfering dedicated bands/channels, interference between shared bands/channels of the two systems is mitigated by a method as recited in the appended claims, interference probabilities are determined and based on these probabilities and interference criteria to be met. Interference is minimized by making initial channel assignments to dedicated channels and assigning shared channels in accordance with traffic controls and limits are developed so as not to violate the interference criteria.

摘要： An apparatus and method for detecting an antenna mispointing condition of an earth station. A noise floor detector, coupled to a received radio communications link signal, measures a noise floor of a selected frequency band in which no radio signals are normally present. A controller, coupled to the noise detector, detects an antenna mispointing condition when a signal strength of the received radio communications link signal is less than a predetermined signal strength and a difference between the measured noise floor and a baseline noise floor measurement is less than a predetermined difference.

摘要： Mechanisms, in a transmission channel shared by 802.11 systems and HIPERLAN/2 systems are provided to prevent 802.11 terminals from transmitting during time periods allocated to HIPERLAN, so that a single channel can be shared between the two standards. In a particular embodiment, a “super frame” format is used where HIPERLAN transmissions are offered the highest level of protection possible within 802.11, which is needed within the 802.11 Contention Free Period (CFP).

摘要： Member nodes of a wireless point-to-multipoint (PMP) network may participate in mobile ad hoc (MANET) or mesh communications with other nodes on the same channels used by the network for PMP communications. A PMP network base station node transmits a downlink signal defining a downlink map for scheduling first time periods for transmitting messages to subscriber station nodes, and an uplink map for scheduling second time periods allowing a subscriber station node to transmit messages to the base station node in a scheduled second time period. A MANET/mesh zone is allocated in either or both the downlink and the uplink maps, each zone operating to reserve one or more time slots and channels in which the base station and other nodes may communicate using a MANET/mesh protocol, thus avoiding interference with communications that are being conducted between the base and the subscriber station nodes under the PMP protocol.

摘要： Various cognitive communications system architectures and their corresponding Protocol Reference Models (PRMs) are disclosed. Such PRMs incorporate a Cognitive Plane in addition to conventional Data and Management Planes. The additional Cognitive Plane functionality may include, for example, spectrum sensing, spectrum management, geolocation, and security functions. The Cognitive Plane may further include a Policy Engine and a Learning and Reasoning Module. In some embodiments, Management Plane functions may be effectively combined to form a database of primitives (and their respective values) called a Management Information Base (MIB). In addition, techniques are provided by which various components of cognitive and non-cognitive, as well as mesh-enabled and non-mesh-enabled nodes in a network, inter-operate with each other. The architectures allow a Spectrum Manager (or Signal Space Manager) to combine information from various network layers (e.g., PHY/MAC Layers, Spectrum Sensing Function, Geolocation Function, and/or Security Sublayers), and to make informed decisions on spectrum utilization.
