Baseband Unit (BBU): Handles baseband signal processing. Remote Radio Unit (RRU): Converts signals to radio frequencies for transmission. Active Antenna Unit (AAU): Integrates RRU and antenna for 5G-era efficiency. 2. Power Supply System This acts as the “blood supply” of the base station, ensuring uninterrupted power. It includes:
The equipment ensures that devices across the infrastructure stack receive reliable power from the mains network, wherever they happen to reside. With it, individuals and organizations can continue to render services to both themselves and their customers. Overviews The 5G network architecture uses multiple types of power supplies.
Higher bandwidths and compression techniques will let 5G networks shuttle more data through systems in a given period, leaving more power-saving idle time. In light of this, the move to 5G infrastructure is necessitating new power supply design considerations.
The backhaul part of the 5G network connects the access interface - including masts, eNodeB, and cell site gateway - to the mobile core and internet beyond. And just like the access equipment, it too has specific power supply requirements. Backhaul power supplies must cater to aggregation routers and core routers.
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.
Experts widely believe that 5G small cells need to be able to continue running in the event of electrical anomalies. Pairing them with integrated power supply devices costs more, but it also protects small cells if there are dramatic changes in voltage.
