"That is something that the other two [telcos] just can't overcome at this stage. It's really been good forward thinking, if you like, by Telstra to make sure that they've got access to the bands that they need for what they want to do and to make sure that they've got access to those bands not only in the city but also in the regional areas," Gregory says.

He says 4G take-up could also be high in the initial stages of the technology rollout, but customers will notice performance changes as more customers join the technology.

"I think the key issue with 4G could be the up-take will be strong and people will find performance will degrade quickly. The other issue that has been raised is the rapid increase in demand for downloads and this will have a great effect on 4G. It will also lead to bill shock over the next six months until new protocols to protect customers kick in," Gregory says.

"I have recently written a couple of times that anything less than 3GB per month is a recipe for disaster."
