In the biggest broadband news to hit the Internet since Telstra was dumped from the NBN process, the incumbent today announced a Cable Broadband upgrade of 100Mbps which will triple existing speeds. Telstra’s timely media release has coincidently surfaced within days of an expected National Broadband Network decision to be made by the Australian Federal Government.
Work on the Telstra cable upgrade roll out will use the latest DOCSIS 3.0 software technology and has been scheduled to start immediately with completion targeted for December this year. The next level of cable broadband speeds is not expected to finish at 100Mbps either, as further upgrade capacities suggest cable broadband potentials can reach speeds of up to 200Mbps.
Although Telstra may be excluded from the Australian NBN process, the Telco still appears to be rapidly releasing upgrades and new features whilst expanding on their already impressive network coverage. It’s almost as though Telstra was seeking to obtain an early ‘upper hand’ against a prospective NBN rival that is due to be announced any day now.
By the end of this year, and provided that all forecasts go to plan, Telstra will have upgraded it’s 2.5 million subscriber cable broadband network to 100Mbps; possibly increased it’s Next G mobile wireless service from 21Mbps to 42Mbps; consolidated broadband Internet access to 99% of the population; and as a result, enabled the potential for millions of people to work from home, improve home automation capabilities and opened the door to an online world of entertainment that includes high definition content viewing.
Funnily enough, this Telstra blueprint could almost deliver high speed broadband of at least 12Mbps (as defined by the Government’s NBN guidelines) to the majority of the population without needing the NBN funding of $4.7 billion? If Telstra was to provide minimum broadband Internet speeds of 12Mbps on both of it’s existing ‘Next G’ and ‘Hybrid Coaxial Cable Networks’, it would only leave an ADSL2+ upgrade to VDSL2 technology in it’s path of meeting the NBN speed requirement.
VDSL2 (Very High Speed Digital Subscriber Line 2) is a broadband Internet access technology that could supercede ADSL2+ services and can theoretically support speeds of 250Mbit/s at the source. However, beyond this distance the speed quickly deteriorates to 100Mbps at 0.5kms, 50Mbps at 1km, then to ADSL2+ speeds (24Mbps) at 1.6kms.
Telstra has already tested VDSL technology and ‘all bets are off’ that this type of technology will be the next in line for a roll out beyond the upcoming cable and Next G upgrades. If VDSL2 does become reality, then Telstra will basically have all the mechanisms in place to compete against an alternative National Broadband Network structure based on the Government’s pre-requisite minimum speed of 12Mbps.
