ADSL vs. Cable Modem — What's the Difference?
By Tayyaba Rehman — Published on January 4, 2024
ADSL (Asymmetric Digital Subscriber Line) uses telephone lines for internet, offering decent speeds but slower than cable. Cable Modem, using TV cable lines, provides higher speeds but can slow in peak times.

Key Differences
ADSL utilizes existing telephone lines to transmit data, allowing simultaneous phone and internet use. It's widely available but speed varies with distance from the exchange. Cable Modem uses television cable infrastructure, offering generally faster speeds that aren't distance-dependent but may slow during high usage times.
ADSL is known for its asymmetric speed: faster download than upload rates, suitable for general internet browsing and streaming. In contrast, Cable Modem often offers higher bandwidth, beneficial for heavy downloading and streaming, but its shared nature can lead to congestion and speed fluctuations.
ADSL installations typically require a phone line and a modem, potentially incurring line rental costs. It's reliable but limited by the quality of the phone line. Cable Modem setups require a special modem and access to cable TV infrastructure, which might not be available everywhere.
ADSL often has more flexible pricing options due to multiple providers using the phone network. It's a good choice for areas without cable. Conversely, Cable Modem services might be bundled with TV and phone services, which can be convenient but sometimes more expensive.
ADSL is generally considered more secure as each user gets a dedicated line to the exchange. In comparison, Cable Modem shares the connection with nearby users, which might pose slight security risks without proper safeguards.
