NBN Co can't guarantee Libs' 50Mbps speed promise: report | ZDNet

NBN Co can't guarantee Libs' 50Mbps speed promise: report | ZDNet: "NBN Co would be unable to offer a guaranteed 50Mbps broadband service under the Coalition's alternative model for the national broadband network, NBN Co has warned in confidential briefing papers prepared for incoming communications minister Malcolm Turnbull.

The limitation is due to the unknown performance characteristics of the VDSL2 technology upon which the Coalition's broadband policy is based. VDSL2's real-world performance is based on the still-unknown condition of Telstra's copper network and the distance of any particular subscriber from the closest network node.

Rather than guaranteeing 50Mbps, internal report warns, NBN Co's 'best effort' service would be the only way to guarantee high speeds under FttN. Image: CC BY-SA 3.0, Secondarywaltz
These performance characteristics, the report warns, mean customers using the Coalition's NBN model could only realistically be offered two guaranteed speeds: 12Mbps (with 1Mbps uploads) and 25Mbps (with 5Mbps uploads)."
