The Challenge of Managing Massive International Events - The Data Tsunami
As one of the largest sports events in the world, the Olympics offers its host country a rare opportunity to serve hundreds of thousands of international visitors, many of whom use mobile services. These users expect their mobile devices to “just work,” the same as they do at home. So when mobile operators get a chance to be a part of this once-every-four-year event, it’s important they get it right.
But delivering flawless mobile service will be no small feat for local operators. Close to half a million tourists came to Rio de Janeiro for the Olympics and Paralympics, along with over 15,000 athletes and officials, some 25,000 members of the media, and roughly 73,000 employees and volunteers. All of them demanded constant mobile service throughout 35-plus competition venues across Rio as well as through connections with their operators from the 200-plus countries they represented.
From my work at some of the most recent Olympics and World Cup competitions, I’ve gotten an idea of just how challenging this demand will be. Specifically, working with one operator at the 2014 World Cup in Brazil, my team helped support mobile services for roughly 1 million visitors, an incredible number of people that exceeded the amount originally forecast by 67 percent and that generated almost 27 terabytes of data traffic over a four-week period.
Through these experiences helping operators take on these daunting challenges at some of the most recent global sports events, I’ve picked up some valuable lessons. Based on this, I’ve identified two areas in particular that will be critical factors in the success of handling massive events. As local operators start serving the massive influx of visitors, their preparations for LTE roaming and real-time user experience monitoring will be crucial determinants of their performance, and benchmarks that all operators around the world should study closely.
LTE Roaming Testing
The transition from “voice first, data second” 3G traffic to today’s “data first, voice second” LTE traffic has involved a seismic shift in the mobile network landscape. As a result, although LTE still only represents a relatively small part of the world’s mobile networks, it represents a sizable foothold in many countries where Olympics fans were traveling from. This is why one factor that will determine the success of mobile service at large public events will be the quality and thoroughness of each local operator’s LTE roaming testing.
The first challenge with this involves ensuring that the right amount of trials were conducted to test LTE interoperability with each operator from the 200-plus countries represented at Rio. This included testing load, throughput and traffic patterns at over 200 venues across Rio, and making sure all those access points were up and running.
But a bigger challenge involves a roaming marketplace fragmented into markets with no LTE service, markets with both LTE and legacy 3G and 2G service, and markets with only LTE service. Operators must have a separate testing strategy in place for a number of roaming situations and fallback scenarios in these three markets. They must ensure that LTE calls seamlessly hand off to older technologies when users travel through areas that lack LTE service, and that users with LTE service enjoy seamless connections to available LTE service with minimal disruptions.
In considering how important it will be to efficiently manage the mobile traffic expected for the Olympics, based on my team’s previous work, we expected each user at the Rio Olympics to consume about 450 MB a day, according to current trends for sharing photos, posting social media updates and streaming videos. Compare this to the 4 MB a day that we measured for users at the 2010 World Cup in South Africa, and it shows the incredible surge in mobile data volume and the critical need to be prepared to handle these loads at Rio. Consider the following stat from SVB: By the end of the third day of events, Akamai, the content-delivery network (CDN) in charge of streaming NBC’s online video, had delivered more data that it did for all 17 days the London Games. Or this: By the end of the eighth day, it had delivered more data than it had for all 34 days of London and Sochi combined.
Real-Time Monitoring
Another critical factor in the success of mobile service at the Olympics was the operators’ ability to monitor users’ roaming experiences and resolve problems in real time. As mentioned above, today’s users expect their mobile devices to “just work,” and they will have other options in any venue if their mobile service doesn’t work, including local SIM cards and Wi-Fi. Real-time monitoring is thereby vital for operators’ ability to deliver the best quality of experience and customer satisfaction.
The latest real-time intelligence technologies help ensure this. They identify network abnormalities, such as data registration failures and traffic patterns, to highlight abnormalities before they affect users. With tools like roaming activity heat maps that graphically show trouble spots, operators can use these technologies to quickly detect problems and drill down to individual user accounts before users become inclined to explore other connectivity options.
Another important tool in these technologies is real-time alerting mechanisms. These put the power of real-time monitoring and usage control directly in users’ hands, with apps that allow them to check their usage details anytime, as well as tools that allow them to receive automatic messages to warn them if they approach their plan limits. These provide powerful safeguards against bill shock.
In addition to these technologies, we have found from our experiences that another crucial component of real-time monitoring is having a local rapid-response capability. At the 2010 and 2014 World Cup competitions and 2016 Olympic Games, we set up on-site 24/7 command centers to proactively address problems. A team of six to eight people helped ensure we could dedicate maximum resources in minimum time to address any problems, often before users could detect them.
Looking Ahead
The Olympics presented one of the largest and most prestigious world stages on which to demonstrate the promise of mobile. As we continue to enjoy massive international events, how local operators manage LTE roaming and real-time monitoring will have profound implications for mobile’s success, as well as for how operators around the world manage future events of a similar scale.
