The COSMOS radio node is an FPGA-assisted software radio design based on a number of COTS components (USRP, RFSoC, etc). The design supports multiple RF front ends including sub-6 GHz and mmWave. The node can be also expanded with additional COTS modules in order to support general purpose legacy services and control requirements. In addition to communication functions, each node can incorporate RF sensing and signal measurement capabilities to support (dynamic) spectrum use and propagation studies. The nodes are available in three form factors, small, medium and large, for mobile, street-level and rooftop installations respectively. The same general components are used for all three sizes, with differences due to the number of antennas supported, radio frequency bands and bandwidth covered, and level of SDR processing provided. These SDR radio nodes work in conjunction with computation on edge cloud servers that can be set up to take on a portion of the signal processing.
