It's worth pointing out that that what Telstra is calling 4G isn't 4G at all. What Telstra has deployed is 1800MHz LTE or 3GPP LTE that at a specification level should cap out at a download speed of 100Mb/s and upload speed of 50Mbps [ed: and the public wonders why we can't just call it 4G?]. Telstra's sensibly not even claiming those figures, but a properly-certified solution that can actually lay claim to a 4G label should be capable of downloads at 1 gigabit per second; that's the official 4G variant known as LTE-A. Telstra's equipment should be upgradeable to LTE-A at a later date, but for now what it's actually selling under a '4G' label is more like 3.7-3.8G. "3.7ish G" doesn't sound anywhere near as impressive on an advertising billboard, though, so Telstra 4G it is.
As someone living in Australia I'd like to point out that there is only one network claiming to be "4G" and that belongs to Telstra (the formerly government owned company that dominates telecoms in this country). The quote above from here
points out that, even though this is the fastest network in this country, it should not be called "4G".
The ACCC is trying to protect consumers from the possibility of, through misunderstanding the labels, buying a product that will fail to meet their expectations. I am not pretending that most consumers understand the true meaning of "4G". Of course they don't understand it - they are consumers not engineers/geeks/marketers or any other category of people who have a vested interest in keeping up with these things. Consumers here in Australia have a network that they now believe to be a "4G" network. If someone such as Apple then advertises a network device as being a "4G" device then it is not unreasonable that consumers would expect the 2 to work together. In the case of the Australian Telstra network and the newest Apple iPad they will not work together. I would have thought Apple would understand this and prefer not to confuse and confound their customers. This iPad is not going to work with any network in Australia as a "4G" device any time soon and so to call it "4G" here is wrong.
To my mind Telstra are wrong to call their network "4G", the ACCC are wrong to allow Telstra to call their network "4G" and Apple are wrong to advertise the iPad as being "4G" in any country but especially in Australia. The world will not see a true 4G network for a good few years and I'm not sure how the marketers will address it's arrival. Perhaps they will talk about "Full 4G" like they talk about "Full HD" for broadcast TV.
