Abstract
In cell-free (CF) networks, a large number of distributed access points (APs) provides communication to a small number of users using the same time-frequency resources. This work presents results related to a CF network at millimeter wave spectrum (mmWave), with carrier frequency of 26 GHz, using a 3D ray tracing simulation. The applied ray tracing simulation is based on the Shooting-and-Bouncing Rays (SBR) method. The propagation environment is based on the Bessa neighborhood in the João Pessoa city, Brazil. As results, are presented a path loss characterization of the considered sites and the computation of achievable rate in the simulated CF networks. The simulation results show that the CF architecture can provide a mean achievable rate of 2.8 bits/s/Hz and 50% of users experience rates greater than 2.6 bits/s/Hz.
