TOKYO -- Nokia Siemens Networks is working with Ballard Power Systems, Inc. to develop mobile networks that can continue to operate during power blackouts. Japanese operator NTT DOCOMO has evaluated the Nokia Siemens Networks Flexi Multiradio base station site offering with integrated fuel cell* backup for potential commercial deployment. The solution has been installed at a DOCOMO R&D Center test site in Japan’s Yokosuka Research Park (YRP).

The fuel cell weight and size are significantly less in comparison to existing lead acid batteries that are typically used in many base stations to provide backup power for extended outages. The base station and fuel cell combination developed by Nokia Siemens Networks with Ballard can provide 4.5 kW of power for approximately 40 hours on a single tank of fuel.

The solution from Nokia Siemens Networks and Ballard Power Systems has already received the Ministry of Economy, Trade and Industry (METI) statutory approval in Japan. After delivering and setting up the fuel cell at a test site in YRP, Nokia Siemens Networks participated in and cleared DOCOMO’s evaluation tests.
