Transmission techniques are provided that improve service continuity and reduce interruptions in delivery of content that can be caused by transitions that occur when the User Equipment moves from one cell to the other, or when the delivery of content changes from a Point-to-Point connection to a Point-to-Multipoint connection in the same serving cell, and vice-versa. The housing includes a pair of opposed walls having a channel or flute therein adjacent outer edges of the vane when the vane is in the closed position. The signal to noise ratio in the received signals is estimated by directly estimating the power ratio, in the received signal, between the part of the frequency spectrum of the received signal that contains only noise, and the part of the spectrum that contains both signal and noise; and averaging this value over a time interval. At a pivot of the cover is positioned a cover sensor to detect the openclose status of the cover.
