For over eight decades WISI has been among the worldwide pioneers of receiving and distributing technology. As a system provider in the product areas of CATV technology, receiving and distribution technology, mobile communication and high-frequency assemblies we have learned during this period not only to maintain the lead in technological development but to continually implement visions into new quality products.
The converging media, new multi-media choices and broadband services demand intelligent transport routes for their distribution. As a developer and technology supplier for the key areas of communication WISI are committed to innovation, now and in the future.
Since its founding in 1926 by Wilhelm Sihn jr., WISI belongs to the global pioneers of receiving and distribution technology. The company deliberately pursues a close integration of research, product development, sales, project teams and on-site production.
In the field of high quality components for the establishment and development of state-of-the-art TV cables and communication networks, WISI is the undisputed market leader and main supplier for the key cable network operators in all of Germany and exports to the major international markets. One of WISI’s foremost principles is to be a permanent and reliable entity for customers, partners and employees.
WISI is committed to providing top-quality components, services and systems for communication and information as well as developing new sectors as the company pioneers into the future.
