  The next generation of wireless networks will use sub-THz frequencies
alongside mmWave frequencies to enable multi-Gbps and low-latency applications.
To enable different verticals and use cases, engineers must take a holistic
approach to build, analyze, and study different parts of the network and the
interplay among the lower and higher layers of the protocol stack. It is of
paramount importance to accurately characterize the radio propagation in
diverse scenarios such as urban microcell (UMi), urban macrocell (UMa), rural
macrocell (RMa), indoor hotspot (InH), and indoor factory (InF) for a wide
range of frequencies. The 3GPP statistical channel model (SCM) is
oversimplified and restricted to the frequency range of 0.5-100 GHz. Thus, to
overcome these limitations, this paper presents a detailed implementation of
the drop-based NYU channel model (NYUSIM) for the frequency range of 0.5-150
GHz for the UMi, UMa, RMa, InH, and InF scenarios. NYUSIM allows researchers to
design and evaluate new algorithms and protocols for future sub-THz wireless
networks in ns-3.
