Nokia Siemens Networks today (1 October 2012) announced the expansion of its Long Term Evolution (LTE) portfolio. The company’s latest upgrades aredesigned to help mobile operators increase their coverage and further improve network efficiency and speed.
Nokia Siemens Networks (NSN) has expanded its Flexi Multiradio Base Station family to cover the APT 700 MHz spectrum to enable smooth LTE (4G) rollouts using the ‘Digital Dividend’ in the Asia Pacific region, Latin America and other parts of the world.
Liquid Radio LTE load-balancing
The company is also increasing the efficiency and speed of multiband LTE today by launching Liquid Radio LTE load-balancing, and is planning the commercial launch of carrier aggregation for LTE-Advanced in 2013. Building on its early experience from the world’s first 800 MHz Digital Dividend spectrum deployment of LTE in Europe, NSN has added a 6-pipe radio module for the APT 700 MHz band to its Flexi Multiradio Base Station family.
This is the industry’s most compact design for widely used 3-sector MIMO2x2 deployments and will enable operators to provide nationwide LTE broadband services in an efficient manner. Japan, Australia, New Zealand, other Asia Pacific countries, and most recently Mexico, intend to adopt the APT 700 MHz spectrum as part of their mobile broadband strategy.
In the world’s most advanced LTE markets, such as South Korea, massive increases in LTE subscriptions are driving bandwidth demand for an additional LTE carrier. Applying its experience from the Korean market, NSN has unveiled a two-step approach for the most efficient use of multiband LTE networks. The company has launched its Liquid Radio LTE load-balancing feature to help operators distribute traffic as and when needed across various LTE carriers.
LTE-Advanced carrier aggregation
In the future, LTE load-balancing will be enhanced by LTE-Advanced carrier aggregation with a simple software upgrade once LTE-Advanced devices become available in 2013. The aggregated bandwidth can double the data speed improving service experience for users and increasing revenue for operators.
‘We consider carrier aggregation as an essential functionality of LTE-Advanced,’ said Kang, Jong-Ryeol, senior vice president and head of network R&D centre, SK Telecom. ‘Together with Nokia Siemens Networks, we have already demonstrated carrier aggregation at Mobile World Congress (MWC) 2012. As one of the world’s leading LTE operators, we are looking forward to providing our customers the superior data rates delivered by the technology.’
‘We are excited to see the momentum in LTE adoption worldwide. With our expanded LTE portfolio, we are committed to helping operators take full advantage of LTE to meet bandwidth demand, offer their subscribers superior data rates and generate new revenue opportunities,’ said Tero Peltola, head of LTE business line at NSN.
Network life-cycle services
The company’s network life-cycle services for LTE include multi-layered network optimisation and LTE network rollout services to minimize technical and commercial risk, avoid disruption to existing users and enable a smooth transition to LTE. With NSN’s comprehensive security services for LTE, operators can provide the same high level of 3GPP-compliant data security that is common in GSM and 3G networks.
The Liquid Radio LTE load-balancing feature will be available by the end of 2012. The 6-pipe radio module for APT 700 and support of LTE-Advanced carrier aggregation will be available during the second half of 2013. The company now has 66 commercial LTE deals globally.
