Abstract

A more efficient antenna can be facilitated by accounting for the cable link loss associated with the distance from antenna base equipment to the antenna. As an antenna transitions between various link layers of a telecommunications network, the cable link loss can be accounted for to determine a compensation value. The compensation value can then be used to account for the cable link loss to allow for a more efficient antenna.
