Calculation of signal attenuation in broadband access networks based on approximation of functions obtained in accordance with COST231–Hata and Okamura–Hat models is considered. The results of the study and data of mathematical modeling in Matcad environment are given. Proposals for practical application have been developed and prospects for its use have been defined.
The success of the promotion of wireless communication technologies is determined by the level of development of telecommunication infrastructure of the regions. The transition to a new generation of standard is the additional placement of base stations on already installed antenna masts. This approach is irrational because it does not take into account the specifics and capabilities of new equipment. The preparation of the territorial plan is a rather expensive procedure requiring a high level of technical expertise. This issue is particularly relevant for companies promoting broadband radio access networks. In view of these circumstances, this article proposes a simplified approach to calculation of signal attenuation in broadband radio access networks, based on the COST231–Hata, Okamura–Khata model in the range from 1,5 GHz, which corresponds to modern radio stations used in broadband radio access networks. The developed approach based on the approximation of Okamura–Hat and COST231–Hata models has a fairly simple analytical description, and the error of approximation based on it of the attenuation function does not exceed 1 dB within the whole range of permissible values.
