Elisa and Nokia Networks have jointly conducted successful tests of centralised RAN under extreme load conditions at the packed Hartwall Arena in Helsinki. Running on the operator’s live LTE network, the solution delivered data uploads more than two and a half times faster, while cutting smartphone power consumption by one third.
No uplink congestion for sports and music fans
Mass events such as hockey games and world-class concerts attract up to 15,0000 fans to the Hartwall Arena. Smartphones are heavily used by visitors to take pictures and videos and share their experiences over social networks. Telecommunications services have to be delivered then and there, with no delays and with the lowest possible battery drain so they can last throughout the event.
And this is exactly what Nokia centralised RAN delivers: it eliminates uplink congestion by embracing interference and turning it into useful traffic. Clever baseband interworking and liquid cells are key here. As demonstrated, it improved the average uplink throughputs by more than 2.5 times and extended the battery life by an average of 33% as devices no longer need to transmit at high power to fight interference.
Nokia centralised RAN technology is built on the company’s Flexi Multiradio 10 base station. The base stations work directly with one another over fibre optic, without the need for additional network elements.
Sami Komulainen, VP, Mobile Network Services, Elisa, said: “We continuously search for new ways to improve our services furthermore. Our co-operation with Nokia guarantees fast LTE-network also in big mass events and our customers can share their experiences in social media.”
Ari Leppä, head LTE product management, Nokia Networks, said: “The densely populated area of the Hartwall Arena was perfect for trialling specific technology for mass events. Our centralised RAN helps Elisa build a dense LTE network to deliver maximum capacity and robust services.”
