Nokia Siemens announced an energy-efficient mobile network equipment package that 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 dramatically decreases. Changing the minimum temperature requirement reduced 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 would also save on energy costs.
