That’s the question on everyone’s lips at the moment because there seems to be no end in sight to the continuing rapid rise in demand for mobile broadband. In fact, we’re convinced that we’ll be seeing 1,000 times more traffic in 2020 compared to 2010. How can network capacity keep up?
The answer is for the industry to evolve to ultra-dense networks. As well as helping operators serve much more traffic than ever before, ultra-dense networks will maximize the investments they have already made in spectrum assets, as well as help them prepare for 5G and the Internet of Things.
But how do we get there from here? How will today’s networks evolve into tomorrow’s ultra-dense networks? What technologies and solutions will be needed to make it happen?
We supplied some of the answers at this year’s Mobile World Congress (MWC) in Barcelona, where we showed the vital components of an evolved network that will allow operators to prepare accordingly.
LTE breaks new ground
We’re taking LTE-Advanced to even greater heights by pushing the technology’s data rates in three dimensions – spectrum, cells and efficiency.
Complementing Carrier Aggregation, we launched MIMO4x4, doubling peak data rates and we demonstrated 256QAM (quadrature amplitude modulation), offering a further 30% boost. In addition, inter-eNodeB-Carrier Aggregation software means operators can build the ultra-dense deployments they need, achieving over 50 macro and metro/small cells per site.
Nokia wins GTI gold award for TD-LTE
TD-LTE will be the technology of choice for many mobile operators, given that TD-LTE spectrum is available for 60% of the world’s population and 50% of the land mass. This is why our innovations shown at MWC included the achievement of TDD-FDD carrier aggregation (CA), TDD uplink CA, TD-LTE-Advanced downlink 3 CA, a high-capacity TD-LTE-A radio and dynamic Nokia Smart Scheduler capabilities.
Also demonstrated was the world’s first TD-LTE-A radio with eight pipes for the increasingly important 3.5 GHz spectrum.
And here’s the icing on the cake: we also won Gold at the GTI awards for TD –LTE market development.
Liquid Radio more fluid than ever
Liquid Radio was also in the spotlight, with new software features detecting and cancelling interference and thus accelerating uploads and response times on 3G networks, cutting the need for site visits and drive tests. Also, our Centralized RAN (Radio Access Network) is more versatile than ever and now supports twice the number of LTE frequency bands and bandwidth (up to 20 MHz for FDD).
Higher capacity for Flexi Zone
Scaling up small cell deployments to ultra-dense networks and very large indoor deployments also got easier with new additions to Nokia Flexi Zone.
We can deliver more capacity with the addition of LTE-A carrier aggregation features, a new dual band indoor Pico base station and new omni-directional antennas. The evolved solution also enables larger indoor coverage and densification with Flexi Zone controller, reduces total cost of ownership with improved Self Organizing Network (iSON) algorithms, and introduces 3G for indoor deployments.
Services will maximize your ROI
Services for HetNets is all about showing operators new ways to maximize the return on their network investments. Consulting services help to compare the total cost of different technical options and guide operators to the best network evolution path. Planning services are powered by 3-D Geolocation to help operators identify the right locations for small cells and make sure they deliver the expected payback. 3-D Geolocation data is also used by a new Multi-Layer Optimization service, which uses Nokia-patented methods to detect interference and simulate the future impact of network traffic. With this insight, Nokia services experts can reduce unnecessary handovers between different radio technologies by up to 20% and ensure that network performance and subscriber experience are optimized.
A lighter carbon foot print
Adding LTE to existing GSM/WCDMA base station sites can add double digit growth to energy consumption. Increasing capacity without raising energy use is therefore a major priority, which we are meeting with over 20 new products and services for our Single RAN Advanced portfolio. The Zero emission base station sites help achieve up to a 70% reduction in energy consumption, while operators can cut the remaining 30% using renewable energy sources on their base stations.
All these new products, services and software features will help increase throughput at the cell edge, leading to more satisfied users, better margins and higher revenues. At Nokia Networks, we are committed to helping you keep up with traffic demand. With our latest innovations, we are building a reliable bridge to the high capacity future.
