5g mobile wireless communication network service using millimeter wave technology
A recently granted patent (Publication Number: US11997506B2) outlines an innovative area construction method for delivering 5G mobile wireless communication network services using millimeter wave technology. The method involves constructing wireless communication areas through line-of-sight propagation of radio waves emitted from a base station using beam-forming technology. The outdoor coverage area is established through paths of line-of-sight propagation, specular reflection, and rough surface scattering by road and wall surfaces, while the indoor coverage area is created by reflected or scattered radio waves within buildings. The patent details the use of U-shaped User Equipment (UE) relays or Customer Premises Equipment (CPE) equipped with beam steering antennas to enhance coverage and functionality, including operating as WiFi access points or LTE base stations.
Furthermore, the patent describes the utilization of LTE or 5G systems in specific frequency ranges to ensure compatibility with satellite communication and avoid interference issues. The method also addresses scenarios such as balcony installations in residential or small office condominiums, ensuring optimal signal reception and coverage. By strategically deploying base stations and utilizing beam-forming functions, the patent aims to maximize coverage efficiency and quality, particularly in urban environments with tall buildings. Overall, the innovative approach outlined in the patent offers a comprehensive strategy for constructing 5G wireless communication networks that optimize coverage, signal quality, and interference management in various deployment scenarios.
