“5G Advanced, heralded by 3GPP Release 18 and
beyond, marks a pivotal moment in mobile
communication, initiating the seamless convergence
of digital and physical realms. This transformative era
witnesses the convergence of XR, Integrated Sensing
and Communication, and the profound influence of AI
and ML on networks, sparking innovation and
redefining connectivity.”
 
Dr. Christina Chaccour, Network Solutions Manager, Ericsson
“3GPP's commitment to evolving telecommunications is
evident in its pursuit of more efficient, reliable, and
versatile networks. The transition from 5G to 5G-
Advanced and beyond signifies a leap in technological
advancements, setting new milestones in connectivity
and network capabilities. As additional technological
advancements are introduced, 6G will be studied with
AI/ML as an integral part of the system, designed to
boost performance and usability.”
