NSN Tests LTE-Advanced Carrier Aggregation

Nokia Siemens Networks has conducted tests of LTE-Advanced carrier aggregation on its commercial Flexi Multiradio Base Station.



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. The LTE-Advanced carrier aggregation demo will also be shown at the Mobile World Congress in Barcelona next week.http://www.nsn.com
