Nokia Siemens Networks has demonstrated LTE-Advanced carrier aggregation on the company’s Flexi Multiradio Base Station. 

The demonstration was conducted at Nokia Siemens Networks’ LTE Center of Excellence in Ulm, using the company’s commercial Single RAN solution.

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.
