NSN has responded to comments made by Alcatel-Lucent that it is a one-trick pony, insisting that becoming a mobile broadband specialist has helped it address a whole host of issues facing operators.

As part of that strategy, in the run-up to this year's Mobile World Congress the vendor announced a raft of new products and services that touch on a number of areas, namely capacity, security, stability, and planning.

"The underlying theme is how we as an industry will carry 1,000 times more traffic on our networks in 2020 compared to 2010," said Phil Twist, head of portfolio marketing at NSN.

"It's about getting more out of existing infrastructure while recognising the fact that the end user wants high-performance broadband without necessarily paying more for it, and also recognising that operators want to be more than just a utility," he said explained to Total Telecom ahead of this year's show.

Highlights from NSN include new software for LTE-Advanced carrier aggregation (CA) deployments and enhanced inter-cell interference coordination (eICIC) for micro and pico base stations. It has released 3D planning tools to help with heterogeneous network (HetNet) optimisation and 'Mobile Guard', a security solution developed with input from malware specialist F-Secure that can spot unusual traffic patterns, block infected services, and notify affected users, even those without antivirus software installed on their device.

NSN has also been showing off 'Predictive Operations', an analytics service that evaluates a vast range of network data to forecast problems up to two days in advance, allowing an operator to pinpoint and solve issues before they cause a serious problem.

Twist said a trial of Predictive Operations is ongoing, and so far "we have seen 95% accuracy of predicting trouble two days in advance".

A lot has changed for NSN in recent years.

It has gone from being the stuttering networks arm that consistently weighed on the profitability of a Nokia driven by its once mighty handset operation to the division that from Q4 2013 accounted for the vast majority of the group's revenue and earnings.

It still has its work cut out to remain competitive with the likes of Ericsson, Huawei, Alcatel-Lucent
