Mobile operator Sonera has launched its commercial LTE-Advanced (LTE-A) network in Finland. The operator is now offering data rates with up to 300 Mbps speeds on live LTE network in certain areas of Helsinki.

In operator's network, downlink data rates of up to 300 Mbps are achieved by aggregating spectrum resources with a total bandwith of up to 40 MHz. 1800 MHz and 2600 MHz frequency band carrier aggregation is being used in Sonera's network. Carrier aggregation accelerates typical user data rates by more flexible radio resource selection in LTE-Advanced networks. 

Operators can create larger, virtual carrier bandwidths for services by combining separate spectrum bands. Sonera now offers data speeds in Finland’s capital up to two times faster than previously possible with 4G LTE. The agreement includes systems integration services and Nokia’s Flexi Multiradio 10 Base Station.

Sonera offers Samsung Galaxy Alpha and Samsung Galaxy Note 4 smartphones to use LTE-A and new devices are being added to the portfolio at the beginning of 2015.
