You can have the fanciest phone or tablet in the world, but it's not much use without an awesome network. That's why we're committed to making our network more amazing every day.
We have been putting in the hours, big bucks and manpower to boost the 3G network, bring 4G to more places and now we bring you 4G Plus, so you can chat, work, play, post and watch - smoother, clearer and stronger - whether you're indoors or outdoors.
Great question. Let's put 4G up against 3G in a fight of the fastest. Spoiler alert: 4G wins!
To get Optus 4G you need to be in an Optus 4G network area in parts of Sydney, Newcastle, Melbourne, Gold Coast, Perth and Adelaide.
You'll also need a plan and 4G phone, tablet or modem, so keep an eye out for the 4G symbol.
To get Optus 4G Plus you need to be in an Optus 4G Plus network area. 4G Plus is already available in Canberra and we're rolling it out in areas of Sydney, Melbourne, Brisbane and Adelaide.
You’ll also need a plan and 4G Plus phone, modem or tablet, so keep an eye out for the 4G Plus symbol.
4G and 4G Plus both give you the same high speed mobile internet. But together they let more customers connect at the same time.
Imagine the mobile network as lanes on a highway. During busy times it can get like peak hour because it's shared by lots more people. So now we're adding a new lane, 4G Plus, which makes the highway wider so more people can use it at the same time. That usually means a better experience in the other lanes too because now they’ll have less traffic.
But we didn't build this type of coverage overnight. Oh no; we've been hard at it since 2005, expanding the coverage to new places, and making it so it can handle more users at the one time.
And the work doesn't stop. We're now boosting the 3G network in heaps of areas which means better coverage indoors.
Check out the latest and greatest 3G and 4G phones, modems, and tablets that let you enjoy our 3G, 4G and 4G Plus networks.
Even if you don't live in a 4G area, it can still be worth grabbing a 4G device. They have all the bells and whistles and you'll be able to feel the speed when you visit an existing 4G area.
This is the new 4G 'lane' we’ve recently added on the 2300MHz frequency spectrum. TD-LTE stands for 'Time Division - Long Term Evolution'. But really, it's just another way of widening our 4G 'highway' so more people can enjoy our 4G network at the same time.
4G is the '4th Generation' of mobile network technology. It's the latest and greatest network available and will be around for a while yet. That's why it's sometimes called LTE (Long Term Evolution).
3G is the '3rd Generation' of mobile network technology. It was a game changer and big step up from 2G, giving us the whole Internet experience - in our hands, on-the-go.
Base stations are the antennas you see on top of buildings and other high spots. They're the things reponsible for getting your phone onto our network so you can call, text and use the 'net.
This is a base station - on wheels, used to boost the network temporarily anywhere where there'll be heaps of people in the one spot. We often bring one of these babies to sporting matches and music festivals.
Latency is a measure of how long it takes for data to travel from your mobile/device to the Internet and back. On 4G, that time is around half of what it is on 3G. Which means quicker everything for you.
