Telstra cranks cable to 100Mbps

Telstra's post-NBN strategy becomes clearer as the company reveals pans to upgrade its cable internet service to 100Mbps.

Telstra has announced that it will boost speeds of its hybrid fibre coaxial cable broadband network to 100Mbps, with Melbourne first in line for the upgrade.

A media statement issued by the company says "Work will start immediately with the installation of DOCSIS 3.0 software and related infrastructure in the Melbourne cable network. Telstra will invest about $300 million in the cable upgrade this calendar year."
