Talking About Green

[Here is a good example of the type of innovation we need for future wireless and wired networks. Although the emission of CO2 by telecommunication networks is relatively small, the rate of growth of these emissions is much faster than from other sectors of society. This is one example of a larger research strategy, of which Ericsson is a partner, to power all components of the network with renewable power including distributed computing, optical repeaters, switches, Internet routers and CPE equipment. This will create new challenges in terms of reliability and restorability of the network. Stay tuned for some major announcements in this field next week at the PROMPT workshop and the California Canada summit on Green IT – BSA]

Ericsson Designs a Wind-Powered Cell Tower
Working with Vertical Wind AB and Uppsala University in Sweden, Ericsson researchers have developed a wind-powered tower for wireless base stations.

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 are currently planned to determine if the design can truly 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 has 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 percent lower.

Furthermore, the Ericsson Tower Tube has no need for feeders and cooling systems. With up to 40 percent lower power consumption than traditional base station sites, it helps operators reduce their operating costs significantly. It employs 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.
