Vodafone admits the current speed advantage of its 4G network in Australia is "temporary".
Vodafone Hutchison Australia CEO, Bill Morrow, said the new network's ability to offer 20MHz spectrum gives it an immediate advantage, but the faster speeds are temporary.
"We currently have over 800,000 4G devices on this network so we feel quite confident that with the physics and the kind of channel structure that we have, our network will remain in a competitive speed perspective, having a temporary advantage," he said.
"I say temporary to be really fair and open to this. Neither of our competitors like the fact that we can go out and say we have the 20MHz, the faster 4G speeds, as this is an absolute race in the marketplace to say who has the fastest, best, mobile data type service."
Morrow said the fact that Vodafone was beaten to the 4G race by Telstra and Optus in Australia isn't a big issue.
"We know we came late to the race on this [4G], we don't think that that necessarily is a big issue today, given that the feedback that we have, and given our 4G network expansion this year."
"We launched 4G at the beginning of this year, part of the reason why we see faster speeds is two reasons. One is the 20MHz spectrum that we offer, you're obviously going to get faster speeds from a physical perspective than you can with a 10MHz channel," he explained.
"The second reason is really because our network has not necessarily been that heavily loaded, and when you load it up the speed naturally comes down."
Vodafone officially switched on its 4G network to customers back in June. At the time, the company claimed the speeds were "among the fastest not only in the country, but in many parts of the world."
Morrow admitted winning back customers, despite a fast 4G network, increased capacity and improved coverage, is the company's biggest challenge.
"We know we're not perfect, we do have hiccups from time to time. The objective that we have given our history is to earn back the trust of our customers," he said.
