What funktel does

Funktel GmbH is a German manufacturer of professional security and communications solutions, headquartered in Salzgitter and founded in 1974, with over 50 years of operating history. The company designs and produces in Germany a portfolio built on three radio technology platforms—DECT (Digital Enhanced Cordless Telecommunications), TETRA (Terrestrial Trunked Radio), and GSM (Global System for Mobile Communications)—covering wireless handsets, base stations, controllers (DC30/DC100/DC200), localization transmitters, and the Nucleus.ASP central alarm server platform. Core competencies are certified lone worker protection (DGUV / DIN VDE V 0825-1/-11), ATEX explosion-protected devices for hazardous areas (Zone 1/2), room-level person localization, warden control for large facilities, evacuation management, and integration with enterprise telephone systems via SIP.

The company serves six primary verticals: correctional institutions and psychiatric clinics, energy and water utilities, healthcare, oil/gas/chemical production, general industry, and emergency services and public authorities (BOS in German). Products are sold through a direct B2B enterprise sales motion targeting medium-to-large organizations requiring specialized safety-critical communication infrastructure, with sales supported by an extensive downloads portal of datasheets, manuals, and compliance certificates in multiple languages. Revenue is generated through hardware sales (handsets, base stations, controllers), recurring software subscription on the Nucleus.ASP alarm server, and professional services for installation and commissioning.

Funktel holds interoperability certifications with major infrastructure vendors including Airbus and Hytera (TETRA), Avaya and Unify/Atos (DECT/PBX), plus six additional TETRA SwMI partners. In 2023, the company acquired OPTRO GmbH in Burscheid to expand portfolio capabilities, and in 2025 it launched the certified FM-S GSM Personal Need Alarm series for lone worker protection. The company is privately held with no external investor structure disclosed and is led by Managing Directors Toralf Hennicke and Rogier Minderhout.
