What SLK Service+ Logistik der Kommunikationstechnik GmbH does

SLK Service+ Logistik der Kommunikationstechnik GmbH is a German specialist provider of BOS (Behördenfunk) digital radio infrastructure, IP-based emergency call systems, redundant command centre (Leitstelle) communication platforms, and intelligent security technology for buildings with special requirements. Founded in 1999 and headquartered in Saarbrücken with a second office in Erfurt, SLK serves authorities and organisations with security tasks, professional fire brigades, rescue services, civil protection organisations, police, public transport operators, and critical infrastructure clients across Germany. The company operates as a wholly-owned subsidiary within ZWF IT GROUP, a German verbund of five IT system houses employing over 150 staff with consolidated revenue exceeding 20 million euros.

The company's product portfolio is built around four pillars: Leitstellensysteme (dispatch centre systems) anchored by the proprietary Ecoms IP-based platform that unifies telephony, emergency call management, and radio query functions; Objektversorgung (building radio coverage) including TETRA-BOS compliant DMO, TMO and TMOa configurations plus fibre-optic distribution networks; Funklösungen (professional radio solutions) supporting DMR, TETRA and Next Edge technologies; and Sicherheitstechnik (security technology) delivered via a certified partnership with Genetec for unified access control and intelligent video. The 2024-launched Ecoms KI extends the Ecoms platform with AI-powered real-time bidirectional speech recognition, translation and voice output to address multilingual dispatch operations. Underlying technology includes fully redundant IP-Notrufabfrage-Einrichtungen (NRAbE), emergency call decoding for TR-Notruf, eCall, TPSeCall and AML, and TETRA TMO repeaters with F90 fire-protection-rated enclosures.

SLK generates revenue primarily through bespoke infrastructure project delivery (planning, construction, commissioning) combined with recurring 24/7 technical support and maintenance contracts with defined SLAs. The go-to-market is direct enterprise field sales targeting government agencies, public safety organisations and critical infrastructure operators, with no e-commerce or reseller channel; customers are acquired via the corporate website, direct contact and partnership referrals. The company holds ISO 9001 certification and membership in the Bundesverband Objektfunk, and is led by Managing Director Willi Zimmerling and Sales Director Ralph Leistenschneider.
