Japan's Docomo will field test three conventional mobile-network base stations that have been installed with solar panels, high-capacity rechargeable batteries and green power controllers.
The telco said the equipment will be used to establish 10 green base stations in the Kanto-Koshinetsu region of Japan by the fourth quarter of 2013, including the first three in Tokyo, Kanagawa and Yamanashi prefectures.
The base stations feature solar panels to generate and store power during the daytime, and are able to run on rechargeable batteries which can store 14-16 hours' worth of power.
"Solar panel power generation can be used during disaster-induced blackouts to operate facilities during the day and store any excess power for nighttime use," said the company in the statement.
Going forward, new features could include the introduction of fuel cell technologies and wind-powered base stations.
