STOV is the Radio Network planning used by Vodafone German to plan new Radio site, to enhance or edit existing Radio network sites. Existing version of STOV is based on the Sybase based database which is almost 20 years old. The existing solution is based on 8 database instances and each instance contains the data of that particular region. STOVAtoll Centralization is going to introduce a centralized database for all user where each user can plan across the regions and make changes according to allocated access rights. Apart from that the Concept of Single Sing On is also introduced where the users are assigned rights to their Windows user and with a single login the users can navigate between STOV and Atoll Removal of existing interfacing to other OSS tools, and the impact analysis before removal of the existing interfaces
