Abstract


The constraints of physical space within buildings pose challenges when accommodating a Base Station (BS) with a substantial number of antennas to harness the capabilities of Massive MIMO (M-MIMO) technology. An approach grounded in practicality to address these space limitations involves deploying multiple antennas on building facades, effectively capitalizing on the advantages of M-MIMO. This article introduces a Matlab-based simulator designed for crafting Extremely Large Aperture Arrays (ELAA) on building facades, validated through mathematical modeling of the system. The methodology entails considering a scenario with a random uniform line-of-sight channel, where User Terminals (UTs) are uniformly distributed within the coverage area of the BS antenna array on the building facade. The system undergoes assessment with a focus on both the radiation pattern and the Interference Reduction Factor (IRF). This approach stands out for its pragmatic and innovative strategy, effectively addressing spatial limitations in built-up areas through the utilization of M-MIMO technology. The viability of the proposed system is substantiated through meticulous mathematical modeling. Furthermore, a proactive evaluation is provided through simulation, offering insights before real-world deployment.
