R&M, the globally active developer and provider of cabling systems for high-quality network infrastructures, based in Wetzikon, Switzerland, illustrates in edition no. 54 of the R&M magazine CONNECTIONS how the LAN is changing from a computer network to a multifunctional network. Installers, planners and users find out about the consequences for structured office and building cabling.

The magazine provides background information and recommendations on new applications such as 10, 25 and 40 Gigabit Ethernet and the upcoming Cat. 8.1 cabling standard. This includes the Internet of Things (IoT), super-fast wireless LAN and innovative zone cabling in office ceilings. The R&M authors report on little-known attenuation effects. They also demonstrate the consequences of the increasing remote supply of terminal devices via data cables, known as Power over Ethernet (PoE).

Current trends are challenging the LAN, the planners and the installers. It is true that 10, 25 and 40 Gigabit Ethernet increase data throughput in copper cabling. But at the same time, electromagnetic influences from outside and inside the cables can affect the signals more easily than ever before. There is no concealed headroom left in LAN cabling. Installers have to work extremely precisely. Planners and decision-makers should only choose high-quality products, advises R&M. Another challenge is the risk of cable bundles overheating when using PoE with higher currents. Here too, R&M advises conscientious installation and product selection. The magazine lists some criteria.

CONNECTIONS also reports on examples of modern workplaces with future-oriented cabling. The reinsurer Swiss Re has created such workplaces in Zurich and Bangalore and relies on connectivity solutions from R&M. Lebanon's largest shopping mall, the ABC Verdun Mall, implemented the multifunctional LAN described above using a solution from R&M. The mall can not only optimally network computer workstations. It can also integrate the POS systems of the shops, surveillance cameras, security systems, digital signage as well as the management of building technology and parking spaces into a single LAN.
