Nokia Siemens Networks systems set to reduce mobile base station site power consumption.

SHENZHEN, CHINA, 20 APRIL 2011- China Unicom’s subsidiary, in Anhui province, has joined with Nokia Siemens Networks to reduce the energy consumption of its mobile base transceiver station (BTS) sites by 20 per cent.

The Chinese state-owned telecommunications operator says it will deploy Nokia Siemens Networks’ Energy Solutions to ensure the sites are more energy efficient.

According to China Unicom the room air conditioner is responsible for most of the energy consumed on a BTS site. The company intends to use cooling box and battery cooling cabinet solutions to replace more expensive air conditioning units.

The operator aims to lower average ambient temperatures to reduce the dependency on expensive air-conditioning reducing total power consumption.

"This is truly a win-win situation for us," said Li Chao, general manager of Anhui Unicom. "It will help us meet the government imperative to mobile operators to reduce energy consumption. In the long run, it will also help us reduce our network operating costs from anywhere between 10-30 per cent, while improving service availability."

Corporate social responsibility

Nokia Siemens Networks is a global enabler of telecommunications services that helps operators reduce energy bills and to address their corporate social responsibility objectives. It says its Energy Solutions provide a comprehensive approach to reduce energy consumption in telecom networks.

Energy consumption, it points out, accounts for 86 per cent of the total energy consumed by operators or 10 per cent-30 per cent of network operating expenditure.

"Our solution provides a comprehensive approach to reduce energy consumption in mobile operators’ networks," said Xue Rui, head of Nokia Siemens Networks’ global services business in Greater China. “Not only do we help operators meet their green targets but also help them do so cost efficiently."
