DSMS Research: Automatic System for Frequency Sharing
The demand for wireless communication is growing explosively. This is due in part to the advent of 5G, the use of smart devices, and the increasing use of drones, making frequencies scarce. The RDI therefore conducted a study in a test environment to determine whether license holders can share frequencies. This involved using a system called ‘Dynamic Spectrum Management and Sharing’. The results of this pilot are promising.
The research took place between December 2024 and September 2025. The aim was to investigate whether scarce radio spectrum can be shared more efficiently. The ‘Dynamic Spectrum Management & Sharing’ system was used for this purpose. DSMS is a system that can automatically and in real-time allocate frequencies to users without causing interference. Users share the same frequency band, but in a more efficient manner than usual.
Tests were conducted with two users in the 3.8–4.2 GHz band: the private 5G network of the Port of Rotterdam Authority was added as a second user to this band. The primary user is the satellite connectivity provider Speedcast in Biddinghuizen.
Measurements show that the DSMS system performed well and successfully protected Speedcast’s services. In the future, the technology could be deployed more widely across multiple networks and in other frequency bands.
