Abstract: A method is disclosed for managing tilt of an antenna providing network coverage over a coverage area. The method comprises obtaining an elevation model of the coverage area and calculating obtaining antenna attenuation to points on the elevation model according to a reference antenna tilt angle and a proposed antenna tilt angle. The method further comprises using the calculated obtained attenuations to predict an impact upon network traffic distribution within the coverage area of changing from the reference to the proposed antenna tilt angle, and approving use of the proposed antenna tilt angle if the predicted impact satisfies an acceptability criterion. Also disclosed are an apparatus and a computer program product configured to carry out methods for managing tilt of an antenna.

Abstract: An improved threaded connection for joining tubulars for oil and gas field operations forms connected tubular strings. The improved threaded connection includes a one piece coupling comprising a body with an outer surface an inner surface and a central axis, a first tapered edge, a second tapered edge, first and second bearing faces for supporting load, weight, or both of the connected tubulars, a plurality of torque stops, and radial metal to metal seal surfaces. As the inner surface of the body is swaged onto each tubular, the inner surface of the body deflects away from the central axis, providing a plurality of bands of high contact pressure at each metal to metal seal between the inner surface of the body and each connected tubular to sustain seal pressures at the threaded one piece coupling.
