Abstract: A communications system includes cellular devices and cellular base stations in communication with the cellular devices in a first frequency band. A non-geostationary satellite may include sensing circuitry operable in a second frequency band susceptible to interference from the first frequency band. Each cellular base station may include a controller and a transceiver cooperating therewith. The controller may be configured to store satellite path data for the non-geostationary satellite, determine when the satellite path data indicates interference would otherwise be experienced by the non-geostationary satellite, and implement an interference mitigation action in cooperation with associated cellular devices based upon the satellite path data indicating interference would otherwise be experienced by the non-geostationary satellite.

Abstract: A satellite communication system may include a terrestrial station and a satellite having a communication link therebetween. The terrestrial station may include a controller and a transceiver cooperating therewith and configured to determine a degradation of the communication link, obtain satellite-derived, rainfall rate and rainfall height data, and determine a rain fade for the communication link based upon the satellite-derived, rainfall rate and rainfall height data. When the degradation of the communication link is caused by the rain fade, the controller determines a mitigation action for the satellite and communicates the mitigation action to the satellite.

Abstract: Method for passively identifying an entity responsible for causing a user equipment (UE) generated uplink communication in accordance with an LTE communication standard. The method includes capturing uplink traffic associated with an LTE communication network. A Demodulation Reference Signal (DRS) group sequence number is extracted from each of a plurality of data packets in a plurality of time slots associated with the uplink traffic. The DRS group sequence numbers which have been extracted are used to determine at least one Physical Cell Identity (PCI) of, or DRS group number used by, a Base Transceiver Station (BTS) entity responsible for causing the uplink traffic.

Abstract: A water irrigation restriction violation system includes a geostationary satellite to collect soil surface moisture data and rain data throughout a given day for a geographic region. A processor and a memory coupled to the processor are configured to store water irrigation restrictions for governmental jurisdictions for the geographic region, receive the soil surface moisture data and rain data from the geostationary satellite, and determine a water irrigation restriction violation based upon the stored water irrigation restrictions and the received soil surface moisture data and rain data. A violation notification is then sent to a corresponding governmental jurisdiction for the determined water irrigation restriction violation.

Abstract: System for passively classifying a signal as a user equipment (UE) generated uplink communication in accordance with in an LTE communication standard includes a radio frequency receiver and a computer processor operatively coupled to the receiver. The system evaluates physical parameters of the RF signals and obtains an extracted bit sequence contained in a time slot in which a Demodulation Reference Signal (DRS) would be normally transmitted. The extracted bit sequence information is compared to a plurality of known bit sequences specified for DRS in an LTE uplink communication.

Abstract: A severe weather detection and warning method may include collecting atmospheric sounding data from at least one satellite atmospheric sounding device corresponding to a grid of localized regions, with the atmospheric sounding data including geospatial location and elevation components. The method may further include collecting weather radar data for the grid of localized regions from at least one radar station, determining a location and direction of travel of at least one moisture system based upon the weather radar data, and determining respective atmospheric instability levels for the localized regions based upon the atmospheric sounding data. The method may also include determining when the direction of travel of the at least one moisture system is approaching a given localized region having an atmospheric instability level above an instability threshold, and generating a severe weather warning indication based thereon.

Abstract: An antenna (100) for RF communications. The antenna includes a radiating member (102) which is substantially tubular so as to define a cavity (104) therein. The radiating member (102) is made of a conductive material having a non-conductive slot (106) extending from a first portion (108) of the radiating member (102) to a second portion (110). An impedance matching device (120) is electrically connected to the radiating member (102) via a conductor (134) to match an impedance of the radiating member (102) with an impedance of a signal source or an impedance of a load. The impedance matching device (120), the conductor (134), and at least a portion of the radiating member radiating element (102) can formed from a single conductive sheet, or molded or extruded as a single conductive structure.
