[MLB-WIRELESS] Melbwireless Digest, Vol 34, Issue 11

Thu Jul 17 13:23:38 EST 2008

I suppose ill chuck my 2.9 cents in,
now, before anyone shoots me... i work for telstra...
now, ill say something else, after working for them, i hate them, and
have no services of theres asside from a home phone which have to keep,
Telstra are quite frankly the bully of the telecom industry in
australia,
now ill explain something a little bit tech side about the next g
network,
the NextG network is a UTMS/HSDPA network,
they use the 850 band, which is only half of the HSDPA specifications
band, thus they actually cut off half of the usable devices on the next
g network, (its why you cant youse alot of hsdpa devices on telstra),

heres the little kicker,
the HSDPA network was not designed to give "everyone" 7.2 mbits as per
what telstra says,
it is designed to share the load between everyone, so that everyones
speed drops while there connection stays stable,
telstra did something to substatiate there claims though, they altered
the next g system so that its packet refreshes slow down,
so that in effect everyone still gets "7.2" but its only burst, not
stream,

if anyone here has a next g device, check your latency to one server
(ping will do),
and then get a GSM device and check your same latency,
i guarentee you that you will find youll have better latency via GSM,

thats not to say hsdpa is bad, its just that telstra's hsdpa has had a
fork stuck in its backside,

the main problem with what they have done is that,
TCP is a 3 way hand shake protocol,
it has to send 3 messages, 
the connection message,
the person you are talking to sends a acknowlegement back to you,
and then you acknowlege there anknowlegement,

hsdpa can handle that, but telstra's hsdpa doesnt handle it well, as
because of its longer broadcast intervals, it has to wait several
seconds before all 3 packets have gone through, 
so your downloads should in effect be "fast" as they will "pulse" at
about 7.2mbit (if your very lucky),
but if you try to do anything like....surfing the internet? or anything
else that uses TCP for the most part,
will be even less reliable then GSM was,

oh and if anyones worrying about optus and there coverage,
there going to be very close to telstra's coverage as of christmas this
year, (as telstra craps itself)

My kind regards,
Adam Grigolato,

I believe they have their own network in metro areas and then roam on another carrier outside these areas. So even though they have the same price as Virgin the limits/restrictions and over limit charges kill it as an option immediately. Read the fine print.......
