Vehicles or Pedestrians: On the gNB Placement in Ultradense Urban Areas

This paper tackles the problem of base stations placement to guarantee line of sight connectivity to vehicles in urban areas, when high frequency communications (mmWave or TeraHertz) are used. We introduce a novel methodology mixing vehicular networks simulations and show that the density of base stations per squared km is low enough to be feasibly reached. However, optimizing the placement for vehicles coverage provides an advantage but may not be enough for pedestrians coverage.
