Wireless will never be more than a supplement to fixed line networks. It suffers from contention, i.e. gets slower as more people use them, from the weather, and to get a better service more towers need to be built, then towers interfere with each other unless they all use different frequencies but spectrum is limited so how do you avoid inter-tower interference?

Honestly....

You need an education.

What's the joke? Most families hate having a tower near them and the fewer the better until we fully understand the health risks associated with the radiation emissions.

The joke is roach does not have a clue re IT.

4G is already suffering slowdowns in the Eastern states due to contention. Contention is just a drawback to wireless networking.

Yay!!!!!!!

The NBN will get my money. I'll see what AiA posts before he posts it! Hope it gets here before 14th September.

Rain challenge for high-frequency mobile broadband.

Samsung today announced a '5G data break-through', but the foundations underpinning the wireless technology are still a long way off.

The South Korean giant said it had carried out tests on wireless data transmission using microwave spectrum, and had reached more than one gigabit per second.

More significant than the speed reached is the use of the very high frequencies in the trials. Samsung achieved the speed using the 28 Gigahertz, which has very short reach or propagation compared to the 3G and 4G 850, 900, 1800 and 2100 MHz spectrum currently used in commercial network deployments. . . .

Another issue with high frequencies 11GHz and over is rain fade, says Jonathan Brewer, a New Zealand-based independent telecommunications consultant and government approved radio certifier.

So it needs a shit of a lot of towers and good luck with that!

If you want a network not disturbed by rain, fibre is there.

Monk,

Are you now telling me that fibre networks don't suffer from contention if too many people are active on it?

Is this what you are saying?

Why do you think the NBN providers have this caveat on their service.

* Speeds are indicative of throughput potential, and not necessarily reflective of actual data transmission speeds.

Also,

"The average person who does regular internet activities is probably not going to notice much difference today,'' Professor Tucker said. ''Where I think it will make a difference is in small businesses.''

Independent telecommunications analyst Paul Budde said right now only about 5 per cent of people, mainly small businesses, would be able to make use of the increased speed.

Confirm what I have been saying that this NBN is an overkill for the audience it intended to serve and that equals ===== waste of money.

Monk,

The NBN also has and will have congestion however it will handle it by the having 4 Quality of Service levels. This has been built into the IP protocols that have evolved over the last 15 years.

Traffic Management & Prioritisation

NBN Co’s product offering will provide QoS options to support voice, video and other QoS sensitive applications (although timing of these options is subject to current assessment). Ethernet and GPON provide the capabilities to support a QoS differentiated product. The LEB and AEB products will support 802.1p identification of Ethernet traffic priority. ...

At this stage NBN Co is planning to support 4 classes of service although it has not been determined when and how all options would become available. They are:

‘Critical’
•Provides guaranteed low levels of delay and jitter
•Suitable for voice and other communicative services. This is the highest priority traffic
‘Expedited’
•Assurances for the levels of jitter and packet loss
•Suitable for video / VOD, including multicast services
•This class provides a second highest priority of traffic
‘Priority’
•Provides a higher level of assurance than the best effort class, with lower probability of delay, jitter and congestion
•Suitable for commercial data services, business grade data services
‘Best effort’
•No performance guarantees
•Suitable for high speed internet
•This is the lowest priority traffic and anticipated to carry high volumes of data with varying levels of performance according to instantaneous congestion

What will happen over time is the end user will be asked to pay for the higher priority of the QoS. This will come once it is implemented.

Watch NBN lovers. You will have to pay for high priority packets on the NBN. When you don't pay you will suffer degradation in performance. To be fair, if the whole bloody thing is over sized, that shouldn't be a problem. One of the tricks in network design to deal with congestion is to over spec it. I don't know if this is the case for NBN.
