A model for comprehensive application of design methods for LTE-1800 TDD standard radio access networks has been proposed, intended for areas where two or more systems operating in 1785-1805 MHz band intersect. This model addresses a methodological gap by providing a universal step-by-step algorithm: initial data collection, comprehensive Electromagnetic Compatibility (EMC) analysis for a cluster of eight nearest base stations, frequency-territorial planning, selection of bandwidth method, and calculation of ser vice areas and seamless handover zones between base stations. A comparative analysis of four approaches (including one with 10 MHz bandwidth) was performed; COST-231 Hata propagation model and precise formulas for predicting coverage, interference, and handover zones were applied. The implementation of this model has reduced risks and costs, ensured service continuity, throughput, and required reliability in com plex areas, confirming its practical significance. An algorithm for selecting bandwidth application method is presented, ensuring adaptation to interference levels and synchronization capabilities. The aim of this work is to demonstrate model's viability and to ensure reliable and stable communication in areas of network in tersection.
