Nokia Siemens Networks (NSN) has conducted a test of LTE-Advanced carrier aggregation on commercial equipment, demonstrating combination of LTE frequency bands to provide improved data rates.Carrier aggregation is a key feature of LTE-Advanced that enables operators to create larger “virtual” carrier bandwidths for LTE services by combining separate spectrum allocations. The showcase is based on the company’s Flexi Multiradio Base Station. NSN has confirmed that the new technology can increase LTE data rates by 90% using a combination of 800 MHz and 2.6 GHz bands.

Nokia Siemens Networks has conducted the world’s first successful demonstration of LTE-Advanced carrier aggregation on commercial equipment. The showcase, which is based on the company’s Flexi Multiradio Base Station, demonstrates its leading role in commercializing the latest technology developments in LTE.

Carrier aggregation is a key feature of LTE-Advanced that enables operators to create larger “virtual” carrier bandwidths for LTE services by combining separate spectrum allocations. The benefits of this aggregation include higher peak data rates and increased average data rates for users.

“We saw an increase in LTE data rates of 90% using a combination of 800 MHz and 2.6 GHz bands, a scenario relevant to the spectrum allocations of many operators,” said Thorsten Robrecht, head of Network Systems product management, Nokia Siemens Networks. “The demonstration underlines our holistic approach to LTE and LTE-Advanced where research and IPR activities are well aligned with product development, targeting real and relevant opportunities for network operators.”
The demonstration was conducted at Nokia Siemens Networks’ LTE Center of Excellence in Ulm, using the company’s commercial Single RAN solution including the award-winning Flexi Multiradio Base Station*.

Customers, press and analysts are welcome to view the LTE-Advanced carrier aggregation demo at the Mobile World Congress in the Nokia Siemens Networks’ Experience Center in Hall 8, C01.
