- Designed to support mobile networks during and after commercial grid outages
- Passed NTT DOCOMO evaluation tests and Japan statutory approval for power supply

/PRNewswire/ - 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 with integrated fuel cell* backup for potential commercial deployment. The solution has been installed at a DOCOMO R&D Center test site in
Yokosuka Research Park (YRP).
"Mobile networks can be vital when a natural disaster strikes, and power outages make other forms of communication difficult," said
, head of mobile broadband energy solutions at Nokia Siemens Networks. "Integrating fuel cells with our base stations can significantly increase the resilience of the mobile networks we provide."
"Our fuel cell systems provide power for extended periods during outages caused by natural calamities and commercial grid failures," said
, vice president of sales at Ballard. "The collaboration with Nokia Siemens Networks has helped us leverage our service and integration expertise in order to deliver an emergency-ready alternative power solution for mobile networks."
Backup power solutions based on fuel cell technology deliver a number of advantages over conventional batteries and diesel generators. These include higher reliability across a wide range of operating conditions, lower maintenance costs, longer operating life as well as reduced size, weight, installation footprint, noise signature and environmental impact.
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 kilowatts of power for approximately 40 hours on a single tank of fuel.
