Infrastructure for the technology enjoyment of tomorrow. Living in the 21st century requires more than just a roof over your head. The concept of "smart houses" not only offers new possibilities for interactively using various media or devices but also makes life more comfortable and secure while helping to save on energy costs. A prerequisite is always the networking of different devices with each other or with the internet. The RJ-45 connection (Ethernet) plays an increasingly important role in this context. It is no longer reserved solely for computers but is being used by more and more devices, whether it's a TV, gaming console, or washing machine. Thus, the Ethernet network represents a forward-looking infrastructure solution. This trend has been addressed by a newly established standard. EN 50173-4 describes the proper installation of application-neutral communication cabling systems in residential buildings. Such an infrastructure, known in technical jargon as structured cabling, guarantees maximum data rates with minimal susceptibility to interference, thus providing an advantage over conventional application-specific cabling.
