WISI – Wilhelm Sihn AG

What WISI – Wilhelm Sihn AG does

WISI – Wilhelm Sihn AG is a Swiss telecommunications infrastructure company founded in 1926 and headquartered in Mägenwil, Aargau. The company designs, assembles, and distributes cable television (CATV), satellite reception (SAT), IPTV, and fiber-to-the-home (FTTH) equipment for the Swiss market, with selected visibility into the broader European broadband ecosystem via trade show participation at ANGA COM in Cologne. Its product portfolio spans the full signal chain—from reception (SAT antenna systems, DVB receivers) through processing (Kopfstellen and Kopfstellen Professional headend systems, IPTV platform) to distribution (interactive cable/HVA networks with DOCSIS 3.1 components up to 1.2 GHz downstream, FTTH optical components including the XGS-PON MicroPlug OLT and the LR11 FTTH converter)—plus multi-standard measurement devices (WO7807/7808/7849) and planning software (Network Designer V4).

The business operates a hybrid go-to-market: direct B2B sales through regional field representatives covering all Swiss cantons, an own e-commerce storefront (shop.wisi.ch) for SMB and individual buyers, and distribution/reseller partners for broader reach. Revenue is generated primarily through unit-priced hardware sales on CHF-denominated ex-works price lists (with 30-day net payment terms and free shipping above CHF 500), supplemented by professional services spanning consultation, planning, implementation, and installer training (Schulungszentrum). The customer base spans cable network operators, telecommunications providers, and FTTH builders as primary segments, with secondary segments including hotels, hospitals, correctional facilities, property managers, and—following the 2021 CO-RM1 launch—schools and offices for air quality monitoring. Strategic delivery is partially executed through a partnership with Instakom AG, a Swiss installation specialist covering cable networks, airports, hospitals, and utility networks. The company is privately held as a Swiss Aktiengesellschaft under Director Arthur Frei and Commercial Director Arthur Huber, with no public listing, no disclosed funding history, and headcount listed at 1-10 employees.

Broad incumbents

• CommScope: CommScope is a large global vendor of broadband, cable, and fiber infrastructure including headend, DOCSIS, PON, and structured cabling. It competes broadly with WISI across HFC, FTTH, and enterprise cabling, but at much greater scale and breadth.
• Nokia (Fixed Networks): Nokia's Fixed Networks group supplies GPON, XGS-PON, 25G PON, and fiber access systems to operators worldwide. It competes with WISI's XGS-PON MicroPlug and FTTH portfolio as a broad incumbent with much deeper R&D and global reach.

Regional players

• Tratec Danmark: Tratec is a Scandinavian specialist in HFC, FTTH, and headend solutions with a similar regional-vendor profile to WISI. Comparable because both target Nordic/Small-country cable and fiber operators with a focused, niche product portfolio.
