5G/6G cellular networks & weather satellite ground stations
We study how cellular networks, especially future 6G systems, impact satellite ground stations in a joint project with the Space Science and Engineering Center (SSEC) at UW–Madison. SSEC operates multiple ground stations on campus, including systems that receive data from low Earth orbit weather and other scientific satellites in the 7 GHz band.
Measuring interference from today’s networks
These ground stations currently experience radio-frequency interference (RFI) from nearby 5G base stations in the C-band. We study how cellular transmissions couple into the receiving systems and characterize their effects on satellite data reception.
Modeling the impact of future 6G systems
We combine observations of existing C-band interference with measurements in the 7 GHz band to develop models of the potential impact of future 6G networks. This work aims to identify the conditions under which cellular transmissions cause interference at satellite ground stations.
Informing coexistence guidelines
Our goal is to provide measurement-based guidance for policymakers on separation distances, maximum transmit power, and other operating limits that allow future cellular systems to coexist with satellite ground stations while protecting reception.
