ZTE has launched an energy saving solution to help operators reduce energy consumption in their LTE networks. According to test results, a single site employing this solution can save up to 40 percent in power consumption.
The global information and communication technology industry accounts for as much as 2.5 percent of the world’s greenhouse gas emissions, according to research firm Gartner. In a typical wireless telecommunications network, about 90 percent of the energy is consumed by base stations.
ZTE’s Energy Saving Solution offers an array of innovative technologies to reduce power consumption for base stations, including the industry’s first integrated system for automatic/dynamic PA bias voltage control and intelligent OFDM signaling shutdown without affecting performance.
Based on test results, ZTE’s Energy Saving Solution can generate energy savings of as much as 32 percent on a single site. Annual reduction of as much as 5,200KwH can be achieved on a typical 1,500W base station. For a network comprising 1,000 base stations, the annual reduction would amount to 5.2 million Kwh, reducing 4500 tons of carbon dioxide emission. When combined with the deployment of renewable energy sources such as solar energy, wind energy or bio-energy, energy savings of more than 50 per cent of the entire network can be achieved.
ZTE will increase resources for LTE development and green technologies. The company has won 38 LTE commercial contracts and is working with more than 100 operators in Europe, the Americas, Asia Pacific, and the Middle East on trial LTE networks.
