Query: Coexistence of 5G mmWave Users with Incumbent Fixed Stations over 70 and
  80 GHz   Millimeter wave spectrum access over the 70GHz and 80GHz is central to
unlocking gigabit connectivity and meeting the explosive growth of mobile
traffic. A pressing question, however, is whether fifth-generation (5G) systems
can harmoniously coexist with the incumbents of these bands, which are
primarily point-to-point fixed stations (FSs). To this end, we thoroughly
analyze the impact of 5G coexistence on FSs. Specifically, we first analyze the
geometry of existing FSs' deployment using actual databases of these stations.
Then, we present a case study on the interference generated from users towards
FSs in two populated areas in Chicago, where we use actual building databases
to accurately compute the aggregate interference. The analysis and simulation
results reveal that the deployment strategy of FSs and the high attenuation
losses at 70/80GHz significantly limit the 5G interference, with the majority
of FSs experiencing interference levels well below the noise floor.
