Abstract: A dual band spectrum allocation system and method for wireless data communications uses discrete bands for upstream and downstream data communications. A preferred embodiment uses unlicensed UNII bands for license-free data transmissions from a subscriber to a hub, and uses relatively interference free licensed bands for data transmissions from a hub to subscribers, thereby allowing use of greater bandwidth, simplifying system licensing and reducing filtering requirements for subscribers.

Abstract: A radar, or other repetitive interference, detection and data flow control system and method for RF data transmissions uses an RF detector and an omni directional antenna to detect radar or similar signals. The information from the RF detector is communicated to a hub data transmission unit which processes the data about the signal provided by the detector. This information is used by the hub to schedule communications between the hub and subscriber units so that none of the communications between the hub and subscriber fall within the time period of the interfering pulses. Although there are no communications during the time periods of the pulses, the efficiency of communications is improved because collisions and retransmission of data are avoided.

Abstract: A wireless RF data transmission system subscriber station has a fixed, overhead bracket secured, spindle. An open sided housing is rotatably mounted to the spindle. The housing has a finned heat sink and is interiorly coated with heat absorbing paint. Emissions shielding enclosures secured within the housing house an RF transceiver. An antenna array mounted to an enclosure is operatively connected to the transceiver through the enclosures for communicating RF data signals. An A/D-D/A board is mounted to an enclosure on an opposite side from the array. A radome is secured over a face of the array, sealed to the housing by a carbon impregnated gasket. An electric motor mounted within the housing and operatively engaging the spindle is controlled by antenna aiming logic for aiming the station and its array. An orifice sealed with a waterproof, breathable membrane allows moisture to escape the housing and prevents moisture infiltration.

Abstract: The present invention is directed to a system and method which statistically determines when regularly occurring interference events of a predictable duration will occur, for example radar pulses and dynamically adjusts an automatic gain control (AGC) for RF data transmissions accordingly. The repetition rate and width of radar pulses are regular. By averaging and watching for correlations, the present AGC identifies the pulse rate and pulse widths and over a fairly short period of time predicts when the next pulse is coming. When the next pulse occurs, the AGC is adjusted to react accordingly. The AGC can raise or lower gain levels for the duration of the pulse; or ignore the pulse, if it is of a very short duration, so that the AGC level will coast through the event.
