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.

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.
