) Siemens Networks (NSN) has announced an energy-efficient mobile network equipment package. The company says that the new package is just the first of a wide range of energy saving initiatives. The energy saving package minimizes the number of base station
sites, reduces the need for air conditioning to cool the sites, uses the latest base station technologies; and optimizes the use of radio access for wireless communications.
The package includes software that can reduce the energy used by base stations by setting some components to enter a power-saving mode at night — a time when network traffic typically drops off. In addition, the package also comes with a feature that changes the minimum temperature requirement for a base station.
While base stations are typically stored indoors, where the air is cooled to around 25 degrees Celsius (77 degrees Fahrenheit), Nokia Siemens (News
) found that increasing the temperature to closer to 40 degrees Celsius can reduce energy consumption at the site by as much as 30 percent.
Nokia Siemens’ energy efficient package also includes network planning tools that can allow operators to use fewer base stations, which is also expected to help save on energy costs. The company plans to shut down part of a base station during times of low traffic, and expects that the move will reduce the need for air conditioning on sites.
“The Energy Efficiency solution makes good green business sense,” remarked Ari Lehtoranta, head of the Radio Access business unit at Nokia Siemens Networks (News
), and also explained that by bringing state-of-the-art products and software together the company can reduce adverse environmental impact while generating considerable cost savings for its operator customers.
Nokia Siemens Networks is planning to cut the energy consumption of some of its mobile base stations by up to 40 percent by 2010. By the year 2010, Nokia said it would reduce energy consumption of its GSM and WCDMA
base stations to 650 watts and 300 watts, respectively, from the current levels of 800 watts and 500 watts.
“We have set ambitious goals that are reasonable both environmentally but also business wise, as energy is becoming more expensive,” said Anne Larilahti, head of environmentally sustainable business at Nokia Siemens.
The company believes the greener products are not only environment friendly but also are capable of saving money for the operators. Larilahti added, “There is also the chance to make a profit,” to have a “net positive” impact with greener products.
