It is the nature of DSL broadband connections that your speed is reduced the further you are from the telephone exchange. There are several reasons for this. The most basic is that the longer the cable is, the more the signal (internet) is attenuated or weakened. Secondly, the longer the cable distance, the more likely there are to be joins, connections or defects in the copper wire – all of which are factors to slowing your internet speed.
The following graph is from the TPG website (http://www.tpg.com.au/dslam/faq.php) and indicates typical speeds of ADSL2+ (including Naked DSL) and ADSL1 over certain distances.
Between 4km and 5km have traditionally been distances at which broadband is sometimes difficult to get. If the cable quality is of poor standard and the line attenuation too high, then an ADSL order is rejected.
But things are starting to change as ISPs now have greater control with their own DSLAMs in exchanges, and they are not restricted by the judgement that comes from Tesltra as to whether an ADSL application will be rejected or accepted. Internode Naked DSL has connected customers at over 7km from the exchange according to their website! I have also seen examples of where iinet Naked DSL and ADSL2+ have been connected at significant distances from the exchange.
How Far Are You From The Exchange?
This is actually more complex than just finding out where your local phone exchange is and measuring the distance to your house using a mapping tool like Google Maps. There are checking mechanisms that the ISPs have which allow them to check actual cable length between your house and the exchange. It is the cable length which is the key and not “as the crow flies”.
