In the digital world, it is difficult to keep up with continuously growing requirements set to new technologies. A few years ago no one was aware of the obligatory installations of telecommunication infrastructure for the future technologies. At that time, the emphasis was put on satisfying current needs, which had later consequences in change of suppliers or delivery of the new solutions connected with assembly of different telecommunication installations. It resulted in not only higher costs, but also decreased the building's aesthetics. In order to ensure the compatibility of installations in the buildings with modern services and various suppliers, a new order MTB and GM was launched on the market. It includes the minimal parameters which should characterize power-low installations. The most economically worthwhile solutions of fiber optic networks in multi-family building are DROP systems (for the small number of users) and EAC-RA (for larger number of users). The perfect complement of given solutions is Logiwiremultimedia cabling system.
