New base stations cut power usage by 70%, claims Nokia Siemens

As operators are forced to considered their ever-increasing OPEX charges, reducing power-hungry base stations costs are becoming a priority. To help with this effort, Nokia Siemens Networks claims its latest offerings dramatically improve the energy efficiency of its wireless networks, particularly the base stations and base station sites.

According to Ari Lehtoranta, head of the RAN business unit at Nokia Siemens Networks, the company has a four-point plan. These include: minimizing the number of base station sites, reducing the need for air conditioning to cool the sites, using the latest base station technology, and deploying software that optimizes the use of radio access.

Using this approach, claims Lehtoranta, can reduce the energy consumption of a base station site by up to 70 percent.

The company pointed to one example where base stations are located indoors--A typical temperature within a base station site of 25˚C is maintained using high energy-consuming air conditioning. However, by increasing the ambient temperature to up to 40˚C, energy consumption can be reduced by up to 30 percent in existing base station equipment.
