Ericsson Embarks on New ‘Green’ Base Station Site

Ericsson has today unveiled a “green” radio base station site concept that the telecommunications giant believes is not only better for the environment but more cost-efficient to adopt and run, and more attractive to look at.

The new design is meant to take a completely new approach to site architecture – the 5m-diameter, 40m-high flexible concrete tower encapsulates all radio base station equipment, including the antennas.

The aesthetics of the site concept, named the Ericsson Tower Tube, have been further enhanced by the choice of construction materials. The flexible concrete tower can be colored and branded to the operator’s specific needs to either blend in with its surroundings or become an attractive landmark for the local community.

And the concrete itself has a lower environmental impact than traditional steel, producing 30 percent less CO2 emissions during production and transportation.

Diverging from standard design, the radio base station is placed at the top of the tower cutting the distance between it and the antenna. This gives capacity and coverage benefits for the cellular network and can together with the fact that no active cooling is needed reduce energy consumption up to 40 percent.

Furthermore, as the new design occupies less land, 60-75 percent less than conventional sites, site acquisition is easier. Being a self-contained structure, operators can also avoid the need for security fences and the cost of maintaining and patrolling them.

Ulf Ewaldsson, Vice President and Head of Product Area Radio, Ericsson, says: “The appearance of radio base station sites has not really been considered before. They have essentially been a steel tower and a container surrounded by a chain-link fence.

“With this new approach, we not only create a more attractive look for this essential piece of community architecture, but we have also developed a design that is better for the environment and more cost-efficient to run.”
