Structured fibre-wireless networks in buildings


Today's building networks consisting of a mix of passive copper cabling and radio stations are no longer up to date with increasing fiber optic house connections (FTTH) and growing mobility. The aim is to establish fiber optic cables as a backbone for active fiber-wireless networks in buildings. In this project, the advantages of fiber-coupled network nodes for radio stations and multimedia outlets will be exploited by further development of the passive structured cabling technology. Innovative components with higher functionality and reduced energy consumption make the technology marketable.

Today, often separate data networks are used for the various tasks such as control (e. g. KNX), television (coaxial cable), telephone (double-wire line), Internet (cat5-7 cable, WLAN). In the future, these data networks will be replaced by a sole network medium - based on optical fibers - and a single data network protocol (here Ethernet).

The basis and background of all considerations for the hybrid fiber-wireless fiber systems considered here is that in today's networks, the bandwidth available to customers is ultimately limited by the bandwidth of the radio cells that all participants share. The range of radio stations is also limited by obstacles such as walls. In addition, there are ongoing discussions and recommendations on the harmless intensities of electromagnetic radiation. In our considerations, this leads to the goal of a radio cell structure that is as small as possible (e. g. one radio cell per room, femtocell). An optical backbone network of fiber optic cables is used to connect these radio cells, which connects the individual radio cells to each other and the devices with a wired network connection on a broadband basis. As optical fibers, polymer-optical fibers (POF) will be the focal point, with advantages and disadvantages of glass fibers (GOF) compared to POF and a comparison with copper-based solutions. This is based on the results achieved so far from the discussions of the so-called "MyPOF" group, a division of OpTech-Net e. V.
