Base station power supply equipment calculation

Does a base station need a power supply?

Base station site planning and network design criteric varies operator to operator but power is often not considered until a particular design state where there are problems regarding the availability of power supply . A typical BTS site requires -48V power supply.

How much power does a base station draw?

VII. POWER DRAWN BY BTS Table 2: Power Drawn by different Base Stations Type of Base Station GSM Base Station 2/2/2 Power Consumption ( may vary with local conditions) 600-1800W GSM Base Station 4/4/4 UMTS Node B Macro/Fiber 2/2/2 900 – 2300W 750 – 1000W Macro/Fiber — 4/4/4 1300 – 1700W VIII.

How to save energy at Base Transceiver Station?

The energy saving at base transceiver station can be achieved by using three basic power saving phenomena's: sleep mode, power saving strategy and power saving mechanism (e.g. RAPS algorithm) or improving design of renewable hardware (e.g., power amplifier) to make it more energy-efficient.

How to reduce base station site power consumption?

Base station site power consumption is primarily from the base station equipment, active cooling, backhaul, lighting& monitoring. There are numerous approaches to reducing power consumption. Removal of active cooling and the use of remote radio heads allow significant reduction in base station site power consumption.

How does a power distribution unit work?

The input power from the supply is fed into the PDU which is the power distribution unit and from there it goes to the rectifier which converts AC supply into DC supply. Typical rectifier and PDU unit are shown in figure 1 and figure 2.

How can a diesel generator reduce base station power consumption?

Removal of active cooling and the use of remote radio heads allow significant reduction in base station site power consumption. Table 1 : Different types of batteries and their comparison ——O——————E—_—_—————_— Diesel consumption varies greatly based on the utility of diesel generators as a power source.
