Who the fck has got 5G internet avaialble.

I resently bought a Optus wireless and it more pathetic then Teltra Bigponds adsl or wireless.

5G is all theory right now.

I use TPG for my mobile phone which is Optus. I get a cheap price and the phone service is fine.

The coverage where I live is very average. BB speeds on the mobile are very ordinary (100 kb/sec or less)

I have a BB Myfi device in the car where I use telstra...... the minimum I get around my area is 2Mb/sec

If your in an Optus 4G area it might be ok but the Optus 4G roll out was limited, I am about 10km's away from an Optus 4G area.

The Samsung development is not 5G and likely never will be. While the test is impressive for wireless it is still ridiculously inferior to the same level of fibre development.

The system being played with by Samsung in development is very high frequency - it is so high that it would not go through paper let alone into buildings or even bus shelters. This technology will fall by the way side. 5G will become a reality but I don't think this one will be available at the projected date of 2020, more like 2030 if ever using this method.

Looking at this type of development testing for fibre and there is an example of a success running at a peta bit. That is a million Gig. Wireless has a valuable place but can not compare to the capability of a fixed service. Not saying that this will go into service any time soon either.

A speed of 1 gigabit per second would require at least 2 GHz of bandwidth, and I'm talking about 2 GHz on the frequency spectrum, modulated to some high carrier frequency above 4 GHz. The higher the speed, the more bandwidth it requires and the more space it takes up on the frequency spectrum. Because a reliable connection always involves transferring more than just the data itself, it's likely that such a connection would require more than just the 2 GHz bandwidth. It would require error correction codes and other stuff. To maintain the required data rate, you might need up to 4 GHz bandwidth, maybe even more.

It's unlikely that they would dedicate such a huge part of the frequency spectrum to the common consumer. This kind of Internet would be too expensive and would likely only be available to people like Rupert Murdoch, Gina Rinehart and Clive Palmer.
