Coexistence assessment and interference mitigation for 5G and Fixed Satellite Stations in C-band in India (2312.16079v1)

Published 26 Dec 2023 in cs.NI, cs.SY, and eess.SY

Abstract: In this paper, we present the findings of a study conducted to assess the coexistence of Fifth Generation (5G) wireless networks and Fixed Satellite Station (FSS) receivers in the C-Band (3300-4200 MHz) in India. Through simulations, we evaluate the coexistence feasibility and calculate the minimum separation distances required to mitigate interference, consider-ing factors such as 5G Base Station power, off-axis angle, clutter, filtering, and shielding. Next, we present various interference mitigation techniques, including distance, antenna tilt and height, power control, antenna design, coordination, filtering, and others, aiming for balanced coexistence. The simulation results corroborate the efficacy of these solutions in containing interference from 5G in the C-Band FSS receivers. The paper offers valuable insights into frequency allocation in India and considerations for 5G network design, including site selection and antenna orientation. The insights provided are relevant to other regions facing similar coexistence challenges. Overall, this paper offers a comprehensive overview of 5G and FSS coexistence in the C-band, emphasising the importance of addressing this issue during network design and deployment.
