Optus vs Telstra Coverage
The Telstra network is one of the world's largest, and covers over twice the geographical area of any other Australian network. Operating on a much lower frequency (850MHz) means that radio frequencies transmitted on the Next-G network travel much further than other networks - the same principle that allows you to receive AM radio almost anywhere, unlike FM radio which fades out as you travel out of town. Optus is rapidly expanding it's 900MHz network frequency to take advantage of this principle, although currently with far less cell towers, Telstra tends to be the better choice when it comes to area covered.
When it comes to 4G, both networks operate on the 1800MHz band, resulting in the same range and distance. As of late 2012 Telstra still has twice the footprint than Optus 4G, but the race is most certainly heating up.
