However, Gregory says spectrum access could prove problematic for Optus and Vodafone in the 4G market and won't be enough to compete with Telstra.

"Optus and Vodafone are both guilty, if you like, of trying to minimise the number of base stations. Part of their problem is that they also have a lot less spectrum than Telstra has. Telstra has been very careful to ensure that they have enough spectrum for systems moving forward and that availability of spectrum has always been Telstra's trump card," he says.

"As far as the mobile phone towers are concerned, it's quite true that Telstra really leads the way in terms of the placement of mobile phone towers, but also picocells and macro cells within places like supermarkets and train stations and other places. Their network is, overall, much more consistent, if you like, than the other two companies."

This will mean while Telstra can continue to roll out its 4G technology, Optus has already hit a brick wall and will be unable to sufficiently carry out its 4G rollout until it can gain access to 700MHz, Gregory says.

Telstra will also "piggy back" on new handsets which are released with 4G connectivity, such as the iPhone 5, according to Gregory, which will help increase the telco's marketshare of 4G customers.
