The telco is undertaking work to improve its network in major stadiums and says it is prioritising efforts to provide customers an enhanced live spectator experience.
A trial is being conducted with Nokia at Sydney’s ANZ Stadium which is designed to improve network performance.
“Customers want to stay connected and get content fast whether they are enjoying the Big Bash League in a stadium or capturing special moments at a major concert. For Optus, we need to trial and explore the technology that will continue to enhance our customers’ experience,” Optus Networks acting Managing Director, Dennis Wong said.
Ray Owen, Head of Oceania, Nokia, said one of the key issues is interference from competing devices trying to access the mobile network.
“This results in devices increasing the power levels they use to communicate with the network, drowning each other out, increasing battery drain, and shrinking network capacity. We are working with Optus to trial Centralised RAN to manage this.
“We are significantly increasing uplink capacity on the Optus 4G Plus network in and around ANZ Stadium, boosting upload speeds while improving download speeds and reducing battery drain.”
Owen says the base stations use uplink signals from multiple cells’ base stations to cancel the interference and select the best signals from 12 receivers. The network configuration is optimised every millisecond for each mobile device according to the actual interference situation, which enhances LTE upload speeds.
