Abstract: According to certain embodiments, a method by a network node (860) for shifting cell borders of multiple frequency bands includes deploying at least two frequency bands. Each of the at least two frequency bands have at least two cells, and each cell have an associated cell coverage area within a common target coverage area. Each of the at least two frequency bands are associated with a respective interference area along a respective cell border, and each interference area is characterized by interference from an adjacent cell. The associated cell coverage area of at least one of the at least two frequency bands is adjusted such that the respective cell border of the at least one of the at least two frequency bands is shifted to reduce a common interference area of the at least two frequency bands. The common interference area is an area where the respective cell borders of the at least two frequency bands overlap.

Abstract: The present invention relates to a small-cell antenna arrangement. The antenna arrangement comprises an antenna mounting unit and an active antenna element. The antenna mounting unit is arranged with fastening means from which the active antenna element is detachable. Further, the antenna mounting unit is arranged with a signalling interface via which signals are arranged to be transferred between the active antenna element and a remotely located base station with which the antenna arrangement communicates. Moreover, the antenna mounting unit is arranged with an interface via which the active antenna element is powered.
