How to reduce interference between 5G base stations and FSS earth stations?

To reduce the interference between 5G base stations (BSs) and FSS earth station (ES), a guard band protection method is proposed. Additionally, the distance and angular protection methods are amalgamated. The performances are evaluated by simulation in realistic 3GPP. Also, the impacts of four antenna types are analysed for a 5G BS.

Can beamformer protection reduce interference from 5G base station to radio altimeter?

Received signal of the radar altimeter at 116 ft in the rural scenario without beamformer protection. 5. Conclusions In this paper, an adaptive beamforming scheme was proposed to mitigate interference from the 5G base station to the radio altimeter.

Are 5G base stations a threat to the aviation sector?

Conclusion Potential interference by 5G base stations operating on frequencies adjacent to the altimeters' band is of concern to the aviation sector, where it could cause disruptions and liabilities to their commercial transport business and operations.

Could 5G interference affect radar altimeter operations?

The Radio Technical Commission for Aeronautics published a report evaluating the impact of 5G communications interference on low-range radar altimeter operations in the U.S. According to the report , 5G communication signals, above 3.7 GHz, could cause harmful interference.

Can 5G systems interfere at multiple altitudes?

The 5G Task Force of the Radio Technical Commission for Aeronautics (RTCA) performed an interference analysis using empirical data at multiple altitudes (RTCA, 2020). This detailed study confirmed 5G systems interference exceeding the safe limit for altimeters.

Can a radar altimeter coexist with 5G cellular services?

In this paper, an adaptive beamforming protection scheme is proposed to enable the coexistence between radar altimeter operating in 4.2 to 4.4 GHz and potential 5G cellular services in 3.7– 4.0 GHz.
