NBNCo has released its updated 18-month rollout plan, after its decision to change it product mix from a Fibre-to-the-Home (FTTH), Wireless and Satellite mix to their new Multi-Technology Mix.
NBNCo’s Multi-Technology Mix includes a number of different technologies including Fibre-to-the-Node/vDSL and Fibre-to-the-Basement/vDSL in addition to the FTTH, Wireless and Satellite services in existence today. It is expected that Greenfield sites, such as new home estates will continue to be rolled out with FTTH where developers and NBNCo can work together.
The NBN 18-month rollout plan can be found on NBNco’s website.
Some people will be upset that NBNCois no longer rolling out FTTH to existing dwellings, as some suggest the Multi-Technology Mix uses technologies that are seen as inferior to Fibre based services, despite most services delivering the same or similar speeds to a FTTH service.
The Multi-Technology Mix include the following technology and access types;
- Fibre-to-the-Home (FTTH)
- Fibre-to-the-Node & vDSL (last mile)
- Fibre-to-the-Basement (last mile)
- Fibre-to-the-Distribution Point (FTTDP)
- Hybrid Fibre-Coax (HFC)
- Fixed Wireless
What access type is used in each area will inevitably be a cost vs. reach decision, with regional areas making use of Fixed Wireless and metropolitan areas using a combination of access methods, that are either in-place today, or are easy to roll-out to existing dwellings.
The biggest concern from some in the industry is the use of the existingand Telstra HFC networks, which NBNCo will eventually purchase from the respective carriers. HFC networks in Australia were rolled out in the late-90’s and early 2000’s and there is some concern over whether they’ll last the distance or keep up with the bandwidth throughput and speeds required over the medium-term.
