This year’s Mobile World Congress in Barcelona was a very busy affair with more than 93,000 visitors over the 4 days from 2-5 March. At times, congestion was a problem for those trying to catch a taxi outside the Fira or get onto the platform at the Europa Metro station. The irony wasn’t lost on us as network congestion was also a big concern for many mobile operators we spoke with, who revealed that data traffic has been growing by up to 100% year-on-year.
So what is the answer? The reality is that there is no silver bullet or single solution to make this problem go away. To resolve this challenge, operators need to densify their networks (by deploying more low-powered small cell base stations); use more radio spectrum; and find new ways to make more efficient use of that spectrum.
Watch the summary video, “Nokia Services for HetNets for urban congestion”, here:
In our Evolution to ultra-dense networks area, Nokia showcased the latest small cells, advanced antenna technologies, and multiple ‘flavors’ of Carrier Aggregation (combining radio spectrum from different base stations, frequencies and technologies to deliver faster data for mobile subscribers).
Our Services for HetNets demonstration explained how Nokia consulting services could help operators compare the cost of different technical options and best prepare their networks for the data deluge. 3-D Geolocation showed how to identify the right locations for small cells, something which is essential as one CTO admits:
“One third of the small cells in our network are in the wrong place.”
Our demonstration highlighted Nokia’s services capabilities to efficiently deploy small cells and the potential use of drones. Use cases here included tower inspection and checking that a clear Line-of-Sight exists between two microwave transmitters. The possible benefits are higher speed, lower cost and reduced risk of injuries and fatalities due to climbing accidents.
Finally, Nokia launched a new multi-layer optimization service that can reduce unnecessary handovers between different radio technologies by up to 20%. It uses patented methods for interference detection and the simulation of probable future impacts of traffic on network performance and subscriber experience. This multi-vendor service can reduce congestion – something we’re happy to help GSMA with at next year’s conference!
Find out more about the demonstrations by visiting the Nokia Solution Experience Center or watch out for our ‘Mobile World Congress revisited’ tours in your country soon. You’re also welcome to read the press release: New Nokia Networks service uses advanced 3-D geolocation to cut handovers by up to 20%, boosting performance.
