Rural telecommunications face unique challenges requiring technological solutions specifically adapted to low population density constraints, infrastructural limitations, and economic sustainability. This research developed a systematic characterization of hybrid wireless network architectures for rural contexts through documentary analysis of implementations in specialized literature. Descriptive-correlational methodology was applied integrating systematic content analysis with performance findings synthesis to identify patterns between technological components and effectiveness metrics. Results established four main configurations: cellular-cell-free with conjugate beamforming, 5G-LPWAN with virtual slicing for IoT, LiFi-WiFi with adaptive handover, and satellite-terrestrial with MEC. Edge intelligence strategies evaluation revealed five distinct approaches: MEET for cost distribution through connected vehicles, LEE for multi-objective energy-learning optimization, collaborative for distributed training, and multi-service for time-critical control. Theoretical implications establish that effective hybridization requires intelligent coordination specifically adapted to rural contexts, while practical implications provide specific guidance for system designers, telecommunications operators, and development organizations in implementing rural connectivity grounded in empirical evidence.
