ADSL2 vs. ADSL2+: What's the Difference?

Edited by Janet White || By Harlon Moss || Published on February 15, 2024
ADSL2 is an improved version of the ADSL technology, offering better speed and stability. ADSL2+ is an enhanced version of ADSL2, providing higher speeds and greater bandwidth.

Key Differences

ADSL2 is an advancement over the original ADSL (Asymmetric Digital Subscriber Line) technology, improving speed and connection stability. ADSL2+ is a further enhancement of ADSL2, primarily focusing on increasing the maximum available bandwidth and data transfer speed.
ADSL2 typically offers internet speeds up to 12 Mbps (megabits per second) downstream. ADSL2+ extends this capability, offering speeds up to 24 Mbps downstream, making it a better choice for more bandwidth-intensive activities like streaming and gaming.
The primary technical difference between ADSL2 and ADSL2+ lies in their use of available bandwidth. ADSL2 uses a frequency range up to 1.1 MHz, while ADSL2+ doubles this range to 2.2 MHz, allowing for higher data transfer rates.
Both ADSL2 and ADSL2+ are designed to be compatible with existing ADSL infrastructure. However, the performance improvements with ADSL2+ may be more noticeable in areas closer to the service provider’s central office.
ADSL2 is often positioned as a reliable and cost-effective option for standard internet usage, while ADSL2+ is targeted towards users requiring higher data speeds and improved performance, especially in urban areas.
