1Productivity
If the number of antennas is increased to achieve Massive MIMO technology, then channel capacity and data transmission capability are improved, but installation space requirements and device complexity increase
Solution Approach 1:
The patent implements a nested structure where multiple antenna elements are arranged in layers, with antenna elements nested within support structures. The arm unit can hold multiple antenna devices at different positions, creating a compact nested arrangement that accommodates numerous antennas in limited space while maintaining channel capacity for Massive MIMO operations
Solution Approach 2:
The patent transitions from two-dimensional antenna arrangement to three-dimensional spatial configuration by using arm units that extend in multiple directions and can be positioned at various heights on support poles. This dimensional expansion allows dense packing of antenna elements in space, enabling Massive MIMO deployment without proportionally increasing installation area
2Area of stationary object
If antenna devices are installed on a single support pole to save space, then installation space efficiency is improved, but installation complexity and difficulty of direction adjustment increase
Solution Approach 1:
The patent incorporates rotatable arm units with rotation units that enable dynamic adjustment of antenna device directions. The arm units can rotate around support poles and adjust tilt angles, providing flexible directional control. This dynamic capability allows workers to easily orient antennas in desired directions while maintaining compact single-pole installation
Solution Approach 2:
The patent divides the antenna support system into modular components: support poles, arm units, and antenna devices. Each arm unit can be independently adjusted and positioned, allowing flexible directional control of individual antennas. This segmentation simplifies installation and adjustment operations while enabling dense spatial arrangement on single support structures
3Area of stationary object
If compact design of antenna modules is implemented to maximize spatial applicability, then installation space efficiency is improved, but heat dissipation and ventilation effectiveness worsen
Solution Approach 1:
The patent utilizes three-dimensional spatial arrangement with arm units extending at different heights and angles from support poles. This vertical and radial distribution creates natural air circulation pathways around compact antenna modules, enabling effective heat dissipation through convection while maintaining space efficiency. The multi-dimensional configuration prevents heat accumulation that would occur in flat, two-dimensional arrangements
