Abstract
In wireless system, a group of Basestations (BTSs) can be managed by a centralized network management identity or can be self-organized by communicating with each other via wireless air-interfaces or wired interfaces. One such example are Femtocell systems. When the BTSs are using the same frequency for transmitting and receiving with relatively large transmitting power and when they are closer to each other, performance of such a system and user throughput or QoS (Quality of Service) gets degraded due to the interference between the BTSs and among the users. Smart antenna technique can be used in a coordinated way among a group of BTSs, such as Femtocells, to avoid or reduce interference or manage how interference happens to achieve performance enhancement such as higher system throughput or better QoS to individual applications.
