Wind loads are crucial in the communication towers design since they are tall and slender. With climate change bringing more storms and higher wind speeds, it is more crucial to research the finest tower structure that withstands such conditions with the least life cycle cost.
Performance factors aside, antennas with better frontal loading design and lesser weight will decrease overall tower weight and wind load issues. Base station antennas add load to the towers not only due to their mass, but also in the form of additional dynamic loading caused by the wind.
stablished a base station antenna wind load working group. This working group has organized several workshops with multiple antenna manufacturers and carriers to normalize wind load standards and wind load calculation methods in the antenna industry. The standardized method of calculating the base station antenna
In addition, antennas, connections, mounts and equipment add load to the towers not only due to their mass, but also in the form of additional dynamic loading caused by the wind. Depending on the aerodynamic efficiency of the overall tower, the increased wind load can be significant.
Building and maintaining a communication base station is a complex process that involves various costs. These costs can be broadly categorized into two main categories: initial setup costs and ongoing maintenance costs. Let's explore these categories in detail. The main loads of those small base station are 48V with rated 500W power more or less, the daily power consumption is about 12kwh. Core energy consumption comes from the main equipment (RRU/BBU), air conditioning, and power supply systems (switching power supplies and batteries).
