Transparent Antenna Solutions for Adaptive Coverage Systems

Roll out of 3G or expansion of maturing 2G, 2 12 G networks – could promote implementation of more flexible infra structure solutions, as resource limitations can make further development or ad-hoc expansion difficult, with the currently used traditional fixed sector base stations. Vendor transparency and possible system transparency is a current feature of most roof installations in 2G and 2 12 G networks, i.e. the antenna system can be acquired independently from base station equipment vendors. This paper describes Adaptive Coverage System (ACS) solutions that maintain similar vendor and system transparency, so no extra supplier constraints are put on possible installation of an ACS in current and future networks.
