, but not all base stations can be guided through, for example, the construction phase at once. The process steps need to be phased and overlapped in order to keep the whole process inside a reasonable time limit. The network planning project management takes care of the whole project organisation. Some support functions, e.g. marketing, selling, logistics and technical support, are also project organisation wide and are not specifically connected to any of the project teams. The network planning team is responsible for both network preplanning and actual network planning, giving site proposals as the output. The network planning team has the assistance of the field measurement team. The site proposals are an input for the site acquisition team, which is responsible for finding the actual site locations. The site acquisition team makes technical site surveys ending up with site lease agreements for the best possible site locations - a decision that is always the sum of several factors. The construction works are carried out by the construction team and the target is to prepare the site ready for telecom implementation. The site location can vary from an existing building to a mast, which has to be built purposely. Therefore the construction work varies a lot from one site to another. Telecom implementation covers installation, commissioning and integration. Installation is the setting up of the base station equipment, antennas and feeders. Commissioning stands for functional testing of stand-alone Radio Network Planning Process network entities. In the commissioning phase it is also verified that the site data depend on the network plan and, for example, the billing and routing data meet the operator requirements. The integration phase verifies that the site is operational as a part of the network. After this it is ready for commercial use. A separate optimisation team or the network planning team is responsible for the prelaunch optimisation phase. Here the field test measurement team is giving support and the a
