ADSL broadband is not available everywhere. Special equipment must
be installed at the telephone exchange and the users must be located within
5.5 kilometres of the exchange. The speed of ADSL Internet service
deteriorates the farther a home or business is located away from the
telephone exchange.
ADSL is not well suited for all Internet applications. Because the ADSL "pipeline" to send data is
comparatively small, Internet applications such as web
conferencing, web hosting, VoIP (Internet telephony) and VPN (Virtual
Private Networking) are not well suited for ADSL (but none-the-less will
work).
