Nokia Networks Advancing to LTE-A Carrier Aggregation Deployment


Nokia Networks is already globally known for its spectrum re-sharing, load balancing and traffic steering in different aspects. Now it is upgrading LTE-A technology globally that offers higher data rates to the subscribers and LTE operators.

Recently, in September 2015, the Nokia Networks have upgraded the Softbank’s commercial network by deploying LTE-A with faster data rates of up to 262.5 Mbps as claimed officially. The 1.4 times faster LTE-A technology has been facilitated with 3-band carrier aggregation on the commercial network.

By upgrading the LTE radio network to LTE Advanced Carrier Aggregation, the mobile network can now be benefitted with three component carriers besides the two aggregated bands. In carrier aggregation technology, 10 MHz spectrum sources are aggregated on the 900 MHz band as well as the 1800 MHz band. While, 15 MHz spectrum sources are aggregated on the 2100 MHz band. To derive the data rate even faster, a data highway of 35 MHz has been deployed in the network which offers about 262.5 Mbps downlink data rates to the subscribers.

The LTE-Advanced Carrier Aggregation technology evolves alongside the subscribers’ demands for higher data rates as well as the capability of their smartphones to support the band combinations of Carrier Aggregation. Today the user equipment are being built to aggregate up to three frequency bands, while some equipment have already been into the market which aggregate two frequency bands at a time. The new LTE-A software by Nokia Networks facilitates the subscribers to achieve the highest data rates that can be supported by their devices and smartphones. With this technology, any combination of the bands can be aggregated out of the three frequency bands.

So far we have discussed the advantages of the LTE-A Carrier Aggregation Technology for the users and subscribers. If we analyze the benefits of this technology from the operators’ point of view, we find out that the LTE operators will now able to drive the development of a wider range of smartphone ecosystem with the three frequency band aggregation technology.

Since SoftBank is considered as one of the top ten largest LTE Operators worldwide, this new frequency band combination will be widely installed in the markets around the globe. When the 900 MHz band for 2G is reframed to the 1800 MHz band for LTE, and the 2100 MHz band for 3G is reframed on the LTE band, the LTE operators get the advantage of higher data rates due to this carrier aggregation of three components.

The LTE-Advanced Carrier Aggregation technology deployment has opened new horizons in the communication technology and set a global example for LTE operators in achieving higher data rates for 4G.
