Open Radio Systems

The Team im March 2025 — The team in March 2025

As radio & open-source enthusiasts, we are revolutionizing the infrastructure of mobile networks. We believe that 6G base stations will run entirely in software and that this software will be open source. For us, sub-nanosecond synchronization is a light breakfast and O-RAN Split 8 is just the beginning 😜!
