Ericsson Unveils Wind-Powered Concept For Its Tower Tube

October 13, 2008 by Jeff Shepard

Ericsson unveiled its latest energy-optimized radio base station site concept, a research project for what is described as a pioneering wind-powered Tower Tube. Working with Vertical Wind AB and Uppsala University in Sweden, Ericsson states that it is developing the concept as part of its commitment to sustainable and cost-efficient solutions that help bring communications to all.

The wind-powered Tower Tube takes the energy-lean design of Ericsson’s original Tower Tube one step further by employing renewable energy. It harnesses wind power via a four-blade turbine with five-meter blades vertically attached to the tower. The vertical rotor blades work silently and minimize the load on the tower during operation.

Trials will be conducted to determine if the design of the Ericsson Tower Tube and the vertical wind rotor blades work together to enable low-cost mobile communication, with reduced impacts on both the local and global environment.

The Ericsson Tower Tube construction houses base stations and antennas, fully enclosing them in an aesthetically pleasing concrete tower. It is said to have a smaller footprint and lower environmental impact than traditional steel towers with CO2 emissions related to materials, such as production an transportation, that are at least 30% lower. Furthermore, the Ericsson Tower Tube has no need for feeders and cooling systems. With what is described as up to 40% lower power consumption than traditional base station sites, it is said to help operators reduce their operating costs significantly. It employs what is described as cutting-edge design and can be built in many sizes and painted in a variety of colors, making it a natural fit for any landscape.

Ulf Ewaldsson, Vice President and Head of Product Area Radio at Ericsson, commented, "Combining wind power with Ericsson’s Tower Tube brings further opportunities to support mobile communication in both urban and remote areas with no or limited access to the electricity grid. Ericsson’s wind-powered Tower Tube research initiative reflects our ambition to use our technical leadership to drive sustainable, telecom expansion and deliver communication for all."
