Fastest ADSL speeds: where SA ranks

Fastest ADSL speeds: where SA ranks 

The OECD recently released its latest broadband statistics, showing that South Africa’s peak DSL speed of 10Mbps is slower than all OECD countries, bar one.

The OECD broadband statistics for the “fastest advertised connection offered by surveyed DSL operators for September 2011” ranks Estonia, Luxembourg and Po land as the top countries – all with a speed of 105Mbps.

The average peak DSL speed among OECD nations is 36Mbps, well above Telkom’s highest speed ADSL service of 10Mbps.

There was in fact only one country which had a peak DSL speed lower than South Africa – Mexico at 5Mbps.

The following graph shows the fastest advertised DSL connection offered by operators in OECD countries for September 2011.

Good news for South African broadband users is that Telkom is currently busy with a network upgrade which will see far higher DSL speeds.

Telkom said recently that it will increase the speed of its entry level ADSL service to 2Mbps by 2015, and at the same time boost its highest ADSL speed to 40Mbps.
