A DISTRIBUTED POWER ALLOCATION SCHEME FOR BASE STATIONS
Photovoltaic power supply method for communication base stations
Solar panels generate electricity under sunlight, and through charge controllers and inverters, they supply power to the equipment of communication base stations, with batteries acting as energy storage units to ensure power supply during nights or overcast days. [pdf]
What energy sources are used to power base stations
Since base stations are major consumers of cellular networks energy with significant contribution to operational expenditures, powering base stations sites using the energy of wind, sun, fuel cells or a combination gain mobile operators’ attention. [pdf]FAQS about What energy sources are used to power base stations
What are the components of a base station?
A typical base station consists of different sub-systems which can consume energy as shown in Fig. 4. These sub-systems include baseband (BB) processors, transceiver (TRX) (comprising power amplifier (PA), RF transmitter and receiver), feeder cable and antennas, and air conditioner ( Ambrosy et al., 2011 ).
How to make base station (BS) green and energy efficient?
This paper aims to consolidate the work carried out in making base station (BS) green and energy efficient by integrating renewable energy sources (RES). Clean and green technologies are mandatory for reduction of carbon footprint in future cellular networks.
How can radio resources be manipulated to conserve energy?
The radio resources can be manipulated to conserve energy by adapting the capacity and/or converge of the green BS. This is demonstrated in ( Valerdi et al., 2010 ), where both aspects are optimized according to the available renewable energy and battery back-up available.
How does a 3 kW BS system work?
In ( Hashimoto et al., 2003 ), a 3 kW BS at an island is powered by 7.6 kW PV panels and and 8 kW wind turbine with 177 KWh back up batteries. Their system comprises a wind generator and cylindrical photovoltaic modules that are mounted onto the wind generator pole to save installation space and cost.
How much energy does a BS consume?
This energy consumption ranges from a few watts to kilo watts depending on the type of BS, with a macro BS consuming most energy, as depicted in Table 3.
What is BS power consumption?
In regulating the transmission power, it is shown in literature that the BS power consumption comprises two components. One is static power consumption attributed to rectifiers, base band unit etc. and the other is the dynamic power which is attributed to the power amplifier (PA).
