Abstract—The evolution of wireless networks is poised to trans-

form the digital landscape with advanced connectivity, speed,
and the ability to support emerging technologies. The transition
from 4G to 5G represents a significant leap forward in terms
of data rates. Reducing latency and connecting devices This lays
the foundation for more information. complex future networks It
enables unprecedented bandwidth and data throughput. Focusing
on higher frequencies (Terahertz spectrum)... Key features of
future wireless networks include ultra-low reliability communi-
cations (URLLC), mass-device communications (mMTC), and
enhanced mobile broadband (eMBB). These advancements in
the Internet of Things (IoT), artificial intelligence (AI), virtual
reality (will support technologies such as VR), automation, which
