The original story on this was more important for what it did not say and thus is missing these big points.

1) The phone has to be NextG (beyond 3G) the only network Telstra will operate soon & not a platform the I-phone currently works.

2) This will also mean (as it is the Telstra model) it will likely get the 33 TV Stations on it from Sky/ Foxtel (at a sligthly higher price

Discussions are ongoing.

So, this will likely be Next G (sometimes called 3.5G) for Australia.
HSDPA is 3.5G. It is an extension of 3G, it uses the same network frequencies. 3G handsets can reach up to 384Kbit/sec. There are two HSDPA networks in Australia. Telstra run off the UMTS850MHz and this is HSDPA enable, they label their network NextG, since they believe its Next Generation.
Optus, Vodafone, Three (and Telstra too, as Three and Telstra co-own the 2100 Network) run off UMTS2100MHZ and this is also HSDPA enable, they just label it HSDPA.

I am not sure about other countries, but there are only a handful of countries which run off the UMTS850MHz frequency, from memory AT&T and Cordova in the States run off 850. UTMS2100 MHz is more widely used.

Note, Telstra claim their network is faster, since it is capable of 14.4Mb/sec. However there aren’t any 14.4Mb/sec devices, their current handsets (only the V6 V3xx and a few of the ZTEs) and turbocards only reach up to 3.6Mbit/secs.

Optus, Three, Vodafone don’t really state how fast the network is capable, but they too have devices which reach up to 3.6Mbit/sec, ie USB Modems and Nokia 6110 and n95, ironically phones which Telstra rejected as they were not UTMS850.

A pair of strange new worlds that blur the boundaries between planets and stars have been discovered beyond our Solar System. The pair belongs to what some astronomers believe is a new class of planet-like objects floating through space; so-called planetary mass objects, or “planemos”, which are not bound to stars.

“Micro-algae have been shown in the past to produce up to 30 times more oil per unit land area, so we’re hoping to achieve growth rates in Australia and create economic feedstock for bio-diesel production,” he said.
Dr Williams says algae could be used to power cars in the future.

Someone recently asked me why is it so hard to deal with a DDOS attack. Simple trying to detect the pattern of the attack. But it all comes down to 3 things.

1. Use a product that allows Service Provider XYZ to detect and mitigates a DDoS attack.

2. Service provider XYZ then securely sends the attack “fingerprint” to the relevant upstream providers affected by the attack.

3. After securely receiving the fingerprint, the information is used by the upstream ISP to trace back, analyze and mitigate the attack, thereby identifying and removing the infected hosts as close to the source [the Internet-based ingress point] as possible.

I have only seen one product that could do this and its the Arbor Networks’ Peakflow SP. I used it on one of the largest networks in the world and it works. As do other large carriers. Keep in mind most carriers are not affected by the DDOS attack (we have the bandwdith). Its the tier2 user and the end customers.

So if you want to make sure you never get hit by a DDOS attack make sure your providers tier1 supplier has the right support in place in case you do get hit and the right preventative measures in place to begin with.

Oh What is a DDOS attack?
