Abstract: A wireless communications system having at least one RIM associated with a remote unit. The RIMs and the remote units (RU) are configured for transmitting and receiving test signal over at least one narrow band of frequencies. The system includes a plurality of signal generators associated with a signal path, each signal generator configured for generating a test signal over the at least one narrow band of frequencies; a controller configured to generate a test signal for the signal path; and, an equalizer for adjusting gain for the signal path according to at least one of the narrow band of frequencies.

Abstract: A method of and apparatus for applying a tension force to a strapping band, and then securing the band with a seal, in order to secure a plurality of goods together, or to secure a package for shipping. The apparatus allows the user to feed the strapping band through the machine so that both ends of the band are secured in a rotating windlass. The windlass is then rotated to apply an equalized tension force to the band. The tension force is divided by the apparatus pulling both ends of the band simultaneously, the resultant forward force on the apparatus therefore being zero. After each banding operation, a return mechanism automatically positions the windlass in an optimum orientation for inserting the band for a successive banding operation.
