- NBN plans vary in price depending on download speeds, but can be as cheap as ADSL plans for the slower speed options
- NBN plans have the potential to be much faster than ADSL2+
- Currently, cheap NBN plans boast similar speeds to what some users already receive on ADSL2+
- The NBN uses a modern architecture that is designed specifically for the high speed transfer of internet traffic.
- ADSL and ADSL2+ relies on an copper infrastructure that was not originally intended for more than telephone calls
Faster speeds should be the main difference you'll notice when connected to the NBN. While ADSL2+ has a maximum potential speed of 24Mbps, most users have much slower connections. This is because ADSL connections rely on close proximity to a DSLAM or interchange. This DSLAM is where the fibre optic cable from an ISP transfers over to the traditional twisted-pair copper used in telephone networks. This copper cabling is not designed to carry large amounts of data and as such, is quite inefficient at it. The greater the distance from the DSLAM to your home, the slower and less reliable your internet connection.
The design of the NBN means that even if you are still connected by copper lines to your house, the distance to the supplier's connection (known as the node) is much shorter.
NBN plans vary broadly in speed and cost, but there are some plans that are comparable to ADSL2+ pricing. The speed of an NBN connection should be noticeably faster, though. Most ADSL2+ connections download data at about 6Mbps. Even the slowest NBN plan should deliver speeds up to twice as fast.
