Innovation is a commitment

For over nine decades WISI has been among the worldwide pioneers of receiving and distributing technology. As a system provider in the product areas of CATV technology, reception and distribution technology, mobile communication and high-frequency assemblies, we have learned 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. This is our business. As a developer and technology supplier for the key areas of communication we are committed to innovation, now and in the future.

Sustainability is our priority

By systematically applying our environmental management system, our processes are in compliance with the standard ISO 14001, from product development through procurement and production through to disposal and recycling. We expect our partners and suppliers to comply with these guidelines as well.

It is our ambition to implement the European Standard WEEE (2012/19 / EU), RoHS (2011/65 / EU) and REACH (1907/2006 / EC), and comply with their updates. Along our supply chain we only accept RoHS compliant processes from our partners and suppliers. The registration number WEEE-Reg.-Nr. DE 83955467 ascertains our compliance with WEEE and the German guideline "ElektroG".
