The power amplifier efficiency of the new generation UMTS/HSDPA Node B reaches 33%, saving 32% of the electricity compared with conventional base stations.
The selection of high-performance Node Bs, reduction of CAPEX and OPEX, network quality and reliability are currently the key areas of concern for operators.
The heightened PA efficiency not only maintains power savings for network operators, but also reduces the investment on power equipment, further simplifying the manufacturing process, lowering the requirements on the heat dissipation of the entire system, and improving the system reliability and performance.
