Small cells are a new part of the 5G platform that increase network capacity and speed, while also having a lower deployment cost than macrocells. The compact size of a small cell requires that all components – especially power converters – provide high eficiency, better thermals and eventually the best power density possible.
A cell tower (also called a macrocell) is a huge umbrella used to provide radio signals to thousands of users in large areas with minimal obstructions. To extend the coverage of a macrocell, distributive antenna systems (DASs) are used in conjunction with the cell tower.
The trend in 5G radio applications is to use higher frequencies and shorter wavelengths. Increasing the frequency increases the speed of sending/ receiving signals and helps shrink the size of the antenna, which in turn shrinks the size of the cell.
The most common method is to use multistage conversion: Table 1. Base station types. first the AC/DC or isolated PoE converter generating the intermediate bus voltage of 12 V or 5 V, and then a point-of-load converter to step down once more to the necessary voltage level.
Our standardized container products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
Small cells are smaller and cheaper than a cell tower and can be installed in a variety of areas, bringing more base stations closer to users. A large number of base stations …
