Australia figures misleading
Wired vs. wireless uptake numbers from Australia are bound to be misleading as many people have to decide between wireless broadband and dial-up, not wireless broadband and wired broadband. In thousands of exchanges around Australia, there simply isn't an ADSL port to be had. (Telstra has under provisioned since day one.) At that point the options are:
* Wireless broadband, if available.
Australian numbers are only meaningful if you compare what choices people have made from the choices *available* to them. As Telstra continues with their TopHat program (adding ADSL2 ports to existing RIMs), we should see greater wired take-up again...until the ports are exhausted.
Note that there's no point asking Telstra as their don't keep a count of how many people are waiting on a wired port to come free. They have a national demand register and they claim to have a 'waiting list' for ports. The waiting list does not exist and the demand register is rarely used.
Given that Telstra's main infrastructure spend has been on 4G networks, it's entirely self-serving for them to claim that people don't want wired Internet. People want it, they just can't get it.
