ADSL2+ typically offers download speeds of up to 24 Mbps and upload speeds of up to 3 Mbps. In comparison, NBN25 provides up to 25 Mbps for downloads and 5 Mbps for uploads, with many ISPs capable of delivering maximum speeds during typical evening usage. Clearly, NBN25 outperforms ADSL2+ with ease.
ADSL2+ relies on existing copper telephone lines, and its speed is influenced by the distance between the user’s location and the telephone exchange. Additionally, bad weather conditions may seriously impact its speed. In contrast, NBN employs various technologies such as FTTN, FTTP, FTTB, FTTC, HFC, fixed wireless and Sky Muster, depending on your location. Particularly with FTTP, fibre-optic cables directly connect your premises, ensuring that your internet performance remains unaffected by distance and bad weather conditions.
As ADSL2+ is an older technology, it lacks the potential for upgrading download/upload speeds, unlike NBN where you have a range of options, spanning from 12 Mbps to 1000 Mbps download speeds, catering to various internet usage needs.
