Indoor mobile coverage solutions
About us
Rosenfelt was founded in Amsterdam in 2012, born from a simple observation: indoor mobile reception was too often unreliable, and the equipment available on the market did not match professional expectations. That gap became our starting point.
Today, Rosenfelt GSM Repeater Systems and accessories are installed in more than 70 countries worldwide, distributed exclusively through a network of professional partners. We work without boundaries — and with a single standard: quality.

Poor indoor mobile reception is rarely a coincidence. In offices, parking garages, warehouses, tunnels and large buildings, the outdoor signal often does not penetrate far enough to be usable. Rosenfelt GSM repeaters amplify the existing outdoor mobile network and redistribute it indoors, restoring reliable voice and data coverage on every supported frequency band.
Each unit is developed by our telecom engineers using high-grade components and the latest amplification technology. The result is a product line that professional installers can rely on, project after project.
Customers in more than 70 countries trust the Rosenfelt network and technology.
We work without boundaries — with one consistent standard of quality.
