The NSN Solution Experience Center hosts superb “Barcelona Revisited” events at our facilities in Karaportti, Finland. “Barcelona Revisited” means that we bring a little bit of Mobile World Congress 2014 closer to our customers. We invite customer employees who could not attend the actual event and tailor content and focus of topics and demonstrations that are most relevant to them. We agree on how to continue the discussions and how we can move forward together so that all are successful.
One of the demos we show to customers is Centralized RAN, a special solution for situations with ultra-high subscriber density and uplink congestion. Have you ever been to a sports event, concert, or any situation with a lot of people having a good time in a small area? Have you experienced difficulties in accessing mobile services during the events or especially during the breaks? I am sure many of you have – and it’s been getting worse, even if operators add temporary capacity.
The reason is that not only are there a lot of subscribers consuming the network capacity in general, but people tend to upload pictures, videos, Instragram updates, Facebook updates, WhatsApp messages, etc. when having a good time. In other words, the traffic is “uplink heavy”. The devices are creating enormous level of interference with each other, trying to shout to the base stations and compete for attention. As a result, network capacity effectively shrinks because the capacity is impacted by interference.
NSN has a unique and patented innovation called Centralized RAN, where we have sophisticated algorithms for reducing the interference in such environments. The demonstration of C-RAN works in such a way that there is a real, commercial Centralized RAN system and a vast number of real devices in a large room. The devices have been programmed to take a lot of pictures all by themselves, one after another, and upload them to the network simultaneously. The pictures appear in a website. It sounds like a room full of crickets when all the devices click away frantically in continuous shooting mode!
Initially, the Centralized RAN feature is turned off, and we can see a “speedometer” of the network capacity reach a certain level. Then, the feature is switched on – and surprise, surprise – the capacity grows and grows and grows. Our operator audiences have been truly astonished. Serving big events, packed with picture-crazy fans is a real opportunity – and the solution is here.
This is one of the coolest demonstrations I have ever seen. I have seen the solution explained on slides and explained by our experts, but seeing it live is believing.
Are you looking to minimize the stadium effect in your network?
