Info from VodaFone on Dual Band

Here are some copies of the e-mails i have received from VodaFone on dual band.. If you read these and think the last one is wrong. you are right, it is wrong!!! heheheh. Even after getting apology from VodaFone about the amount of miss-information/lack of information on the subject.. VodaFone AU is STILL unable to tell me were it is available in AU. :-)

Ok a good start.

I'm not sure what went wrong here but I am happy to inform you that the
first dual band towers were activated in the Albert Park area for the Grand
Prix last week. More towers are going on line in Melbourne and Sydney this
week and the roll out will continue in the coming months. I am still trying
to determine if we will be updated on which particular areas have been
completed.

Regards
Brad


Still Ok.

Hello again Tim,

Tests are continuing on several sites in Sydney at present. Roll out dates
and further information will become available on the Network's web site when
it is deemed appropriate.

Hi Tim,

The only site set up in Australia at this point in time is our Head Office
at Chatswood in Sydney. This is an internal site that spills outside into
the courtyard area only. As previously stated it is not (GSM1800 dual band) available to the public apart from this.

Regards
Brad Vines


Since then I received an apology (from VodaFone AU) about not being able to get any info from VodaFone about Dual Band coverage areas. But even after that VodaFone AU STILL doesn't even know were dual band is available.


Tech Note

GSM 1800 uses Channel (CH) numbers between 512 and 885, 1710 MHz-1785 MHz Mobile (phone) Transmit (TX) and 1805 MHz - 1880 MHz mobile (Phone) Receive (RX).


Reference info was gather from the ACA web page http://203.37.2.230/pcs/Picture.htm

And ETSI GSM specs (GSM 05.05)
