In September 2025, a new IEEE Milestone was unveiled at Nokia Labs in Antwerp, Belgium, celebrating the development of the pioneering Asymmetric Digital Subscriber Line (ADSL) system. The ceremony, presided over by IEEE President Prof. Dr. Kathleen Kramer and Region 8 Director Prof. Dr. Dušanka Bošković, was attended by over 200 former project collaborators and IEEE members, marking a celebration of Belgian innovation and the global impact of this technological achievement.

The IEEE Milestone citation reads:
“Asymmetric Digital Subscriber Line (ADSL) Enabling Broadband Internet, 1993-1997. In 1997, Alcatel’s A1000 ASAM product revolutionized broadband Internet access by providing multi-megabit per second downstream speeds over ubiquitous but decades-old and ill-conditioned subscriber telephone lines. A team based in Antwerp, Belgium, began development of the product in 1993. The combination of ADSL technology, innovative signal processing, cutting-edge silicon integration, and a revolutionary architecture brought affordable broadband Internet to nearly one billion people worldwide.”
Asymmetric Digital Subscriber Line (ADSL) is a broadband technology that delivers high-speed internet over existing copper telephone lines without interrupting voice service. It featured faster download speeds than upload speeds (asymmetric), using specialized frequencies to enable reliable, cost-effective web access, streaming, and data transfers for homes and businesses. ADSL was crucial in the mid-to-late 1990s in helping users transition from slow dial-up to “always-on” high-speed internet, representing a major milestone in telecommunications history. Its ability to leverage millions of pre-existing copper lines enabled rapid, widespread adoption without replacing infrastructure.
