High altitude 5g base station communication distance

What is a high altitude platform station?

Abstract—The high altitude platform station (HAPS) concept has recently received notable attention from both industry and academia to support future wireless networks. A HAPS can be equipped with 5th generation (5G) and beyond technologies such as massive multiple-input multiple-output (MIMO) and reconfigurable intelligent surface (RIS).

Are airplane altitudes accurately measured by a 5G New radio system?

The simulation results describe that the altitudes of the airplane are accurately measured by the proposed scheme. 1. Introduction Spectrum management becomes more complex as the middle-frequency FR1, up to 7 GHz, of 5G New Radio (NR) systems extends beyond the bands used in Long-Term Evolution (LTE) .

Does adaptive beamforming reduce interference from 5G base station to radio altimeter?

5. Conclusions In this paper, an adaptive beamforming scheme was proposed to mitigate interference from the 5G base station to the radio altimeter. Compared to the conventional beamformer with fixed weights, the proposed beamformer adaptively changes the weights according to dynamic environment.

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.
