Frequency-Independent Asymptotes of System Parameters of Urban Cellular Communications at Multipath Propagation of Radio Waves

Abstract

Frequency-independent relationships for estimating a following number of system parameters of cellular communications under the conditions of multipath propagation of radio waves in urban canyons and the presence of intrasystem interference are obtained: the required equivalent isotropic radiated power (EIRP) of subscriber stations, the maximum data transmission capacity of the uplink radio channel, the maximum distance of qualitative communication, and also the permissible level of intranetwork radio interference at given requirements for communication range and data transfer rate of uplink radio channel taking into account the accepted restrictions on EIRP of subscriber radio equipment. Together with the frequency-independent component of the electromagnetic background near the earth's surface, created by electromagnetic radiations of subscriber stations located outside the breakpoint vicinity of the observation point, these dependencies form a family of asymptotes that provide ample opportunities for system analysis and diagnostics of solutions and scenarios for the implementation of 4G/5G/6G systems and services in various conditions, taking into account the quality of frequency-spatial planning and the intra-system EMC design of radio networks of cellular (mobile) communications.
