Going to see sport will never be the same
Imagine going to watch the footy and being able to see the game crystal clear, no matter where you're sitting.
And to be able to see the field from a player's perspective.
And to have your favourite meal and drink pre-ordered for you and delivered directly to your seat without having to lift a finger.
Advancements in 5G technology will soon lead to "smart stadiums" where all these things are possible for your viewing experience.
Instead of lining up to show your ticket and ID to get inside, facial recognition technology will slide you right on through.
If you miss a key moment, you can point your phone at the try line and watch it back in crystal-clear vision.
If you want a more personalised experience, you can point your phone anywhere on the field and see a specific player in action.
Optus head of mobile access planning Kent Wu said the additional bandwidth from 5G would make for crystal-clear viewing at smart stadiums.
"Watching 4K videos on your portable device will become a major trend in 2020," he told news.com.au.
He also said Optus had partnered with tech start-ups to enable the virtual and augmented reality experience, saying it would allow people to use their phones to "almost take on the role of a player or referee". The user can see what the game looks like from their perspective.

Ordering food and drink from the canteen will become hassle-free too. Rather than waiting in line and stressing over whether or not it's cash only, you can have your food pre-ordered for you and delivered to your seat, similar to meal service on a plane.
The hassle of buying tickets will be made easier too - and showing them at the gate will become a cinch.
"Usually, you would need to hold your ticket and ID passes to gain access to the stadium. Through working with video and analytics, 5G can use facial recognition to use the biometric IDs instead of physical IDs. Getting the spectators into the stadium will be a lot more orderly and easy," Mr Wu said.
He said there would be a wide range of sensors installed around stadiums that saved power and were environmentally friendly.
Mr Wu said the biggest difference when people switched to 5G would be the speed, which "opens up a huge bandwidth to deliver crystal-clear Ultra HD content".
"We are in the early stages of our 5G rollout with over 300 sites located across Sydney, Brisbane, Melbourne, Adelaide, Perth, Canberra and other key locations outside of the capital cities areas," he added.
"The additional bandwidth and capacity that 5G will provide will only continue to improve as the 5G network is built out and densified. For Optus, it's about building a 5G network powerful enough to cope with the huge demand that is put on the network as tens of thousands of festival-goers or sporting fans upload videos to social media, message their friends or simply browse the internet throughout an event.
"Before 5G-dedicated coverage solutions are installed in these locations, we are also continuously expanding the 4G capacity in these areas so that the majority of our 4G customers can also have a better experience.
"In the future, as 5G connectivity matures and improves, we also expect that it will change the way attendees interact with large-scale events. This could mean the use of AR and VR technologies at these events."
