  The potential of the millimeter wave (mmWave) band in meeting the ever
growing demand for high data rate and capacity in emerging fifth generation
(5G) wireless networks is well-established. Since mmWave systems are expected
to use highly directional antennas with very focused beams to overcome severe
pathloss and shadowing in this band, the nature of signal propagation in mmWave
wireless networks may differ from current networks. One factor that is
influenced by such propagation characteristics is the interference behavior,
which is also impacted by simultaneous use of the unlicensed portion of the
spectrum by multiple users. Therefore, considering the propagation
characteristics in the mmWave band, we propose a spatial-spectral interference
model for 5G mmWave applications, in the presence of Poisson field of blockages
and interferers operating in licensed and unlicensed mmWave spectrum.
Consequently, the average bit error rate of the network is calculated.
Simulation is also carried out to verify the outcomes of the paper.
