Stadiums, concert halls, train stations, festivals in parks, convention centers – these are all types of venues that bring a large concentration of people together in a small area. For operators, this means having high traffic demand in a dense environment with subscribers using mobile broadband services in ever-increasing amounts. This creates problems for operators, specifically in the form of high interference, which requires advanced interference management to ensure a positive customer experience for end users.
Let’s look specifically at stadiums. There are a lot of stadiums in the world. And I mean a lot! The folks at World Stadiums have a comprehensive database that list more than 12,000 stadiums in over 224 countries. And of those, nearly 1,000 stadiums can pack in 30,000+ spectators and their mobile devices. What’s more interesting is that there is a shift in the mobile broadband traffic pattern use at these venues. People aren’t consuming content as much as they are making it and sharing it themselves. Uplink data traffic at major stadium events has actually been greater than the downlink, as people upload pictures, videos and other content from their smart devices.
Meeting this high traffic demand requires the deployment of multiple base stations in order to provide the necessary capacity to carry the broadband traffic. The problem in this deployment approach is that the base stations will have a small inter-cell distance. This close proximity of cell sites will create considerable interference from mobile devices, which reduces network capacity and impairs service quality.

To help operators address this issue, NSN introduced its Centralized RAN solution at Mobile World Congress 2014. Already successfully deployed in South Korea with LG U+, this Centralized RAN solution links multiple LTE base stations to work directly with each other to reduce interference between neighboring cells. It essentially turns interference into usable throughput traffic. NSN enables this by having all of the base stations work together directly over fiber optic, without the need for additional network elements.
This approach has huge value for operators as it can double the average uplink capacity across a cell, while uploads at the cell edge can be up to ten times faster. And what’s even better is that all of this functionality works on our existing Flexi Multiradio base station platform, making it immediately available to operators.
